Battery Chemistry Information

Friday, July 31st, 2009

Sounds simple, right? Pick a chemical makeup and run with it. Not so fast. “There are as many, if not more, recipes for these notebook batteries as there are companies that supply them,” says Denise Gray, director of hybrid energy storage systems for General Motors. “Automakers need to experiment to find which works best for them. That takes time. We need them to perform as a function of driving style, location and climate. They need to deliver both power and range when needed, every time it’s needed.”

Like other hp laptop battery,hp 338794-001 battery those that use lithium work by shuttling ions (electrically charged atoms or groups of atoms) between their electrodes. When they’re charging, the ions travel in one direction. When they’re discharging, they go in the other. The most widely used have a positive electrode made from cobalt or manganese oxide and a negative electrode made from graphite. The electrolyte (the material through which the ions pass from one electrode to the other) is a lithium-based gel or polymer. These types of batteries are mainly used in laptops, and are not well-suited for the automotive environment, where they’re subject to rapid discharging and recharging, much higher power demands and extremes of heat and cold. The problem is that the chemistry isn’t stable enough, so batteries suffer from overheating—and that can have an explosive effect.

The most promising electrode chemical makeups, then, involve nano-engineered materials like phosphates of iron, lithium-titanate spinel and, most recently, bundles of silicon nanowires. Making an electrode out of these tiny particles increases the available surface area for the ions to bond to and exchange electrons, avoiding a bottleneck that used to result in deformation (and diminished effectiveness) of traditional materials like graphite. The smoother-flowing electrode decreases the battery’s internal resistance and improves its ability to store and deliver energy.

Some battery companies have hp 361742-001 battery,hp 371785-001 battery recipes that are ready for series production now, at least for mild hybrids. Milwaukee-based Johnson Controls/Saft, one of the industry’s top manufacturers for outsourcing hybrid chemistry into Saturn’s Vue series and Mercedes’ diesel hybrid (details on next page), has been touting research it calls NCA, which has been approved for mild and full conversions by OEM powerhouses. “It has demonstrated the required combination of power, range, safety and longevity,” says Mike Andrew, director of Government Affairs and External Communications at Johnson.

Meanwhile, Toyota appears to be close, if not locked into its chemistry, for a demo fleet of plug-in hybrids. In Detroit earlier this month, Toyota’s president Katsuaki Watanabe said they would be accelerating development to have a large-scale (an estimated several-hundred-to-a-thousand-vehicle) test fleet in service by 2010 or earlier. When pressed, he said these demo cars could be on the road by late 2009. So, in order to meet that target, we hear Toyota has the chemistry nearly finalized for their first-generation of electric cars.

Even so, there doesn’t seem to be a clear winner here or a one-size-fits-all solution. “The chemical makeup will, in part, depend on application,” says Dave Vieau, CEO of battery supplier A123 Systems. “One type of lithium-ion hp 372772-001 battery,hp 398876-001 battery might be better for use in hybrids, while another is better for plug-ins.” As PM detailed last year in a cover story on plug-in research, A123 is one of the leaders in this field, with phosphate particles in its electrodes that shrink to about a hundredth of the size of the oxide particles used in existing li-ion batteries. That was good enough to score the MIT geeks at A123 a massive contract with GM to work on its Chevrolet Volt, the power system for which they’re currently developing.

And it’s going to take a lot more practical application to figure what works over the long run. “It’ll take companies like AC Propulsion and Tesla to put some products on the market to see what works and what doesn’t,” says Tom Gage, president and CEO of AC Propulsion, makers of a Scion-based hp 417066-001 battery,hp 346970-001 battery vehicle conversion they call the eBox. “Right now, the market is too small for the top tiers to produce anything.”

Laptop Battery Life Benchmarks Are out of Juice

Friday, July 31st, 2009

In an industry that gets off on throwing obscure benchmarks at buyers ( “pixel fill rate,” anyone?), laptop battery life is one of the easiest to understand.

It’s also long been one of the least useful, critics charge, due to the industry’s deceptive use of the dominant standard, the MobileMark benchmark created by the Business Applications Performance Corp. (BAPCo), an industry consortium whose members include Intel Corp., Dell Inc., Hewlett-Packard Co., Advanced Micro Devices Inc. and others.

“Everyone in the industry knows this benchmark is wildly optimistic and that the actual battery life you’ll get is often less than half what MobileMark suggests,” wrote analyst Rob Enderle last month. “This is because MobileMark measures battery life much like you might measure gas mileage if you started the car, put it in neutral, and coasted down a long hill.”

The latest MobileMark 2007 report measures laptop battery life under three scenarios: reading a document, watching a DVD movie, and doing a “representative” mix of productivity tasks, such as reading and composing documents, editing photos and encoding Flash videos (see page 13 of white paper).

But rather than using an average time based on all three measures, BAPCo designates its third scenario as the way most people use their laptop.

There are several problems with this, according to critics. First, doubters such as AMD say that the productivity test assumes that the notebook is idle 90% or more of the time.

Second, MobileMark’s “productivity” scenario assumes that users, when active, are using only software such as Adobe Photoshop or Microsoft Office. They don’t test usage of music or video applications such as iTunes or Windows Media Player, games or Web browsing. The test also assumes that Wi-Fi is turned off.

That seems particularly unjustified today, since netbooks are touted as on-the-go, Web-centric devices, or high-definition video-capable machines.

Finally, MobileMark 2007 allows PC vendors to set their laptop screen brightness at the lowest possible setting, provided it is no lower than 60 nits (a nit is a measure of brightness. The problem, again pointed out by AMD, is that 60 nits is quite dim, being only about one-fifth of most notebook PCs’ maximum screen brightness.

According to an informal reader poll at Neowin.net, a Windows community site, fewer than 15% of respondents run their notebooks that dim.

BAPCo defended its MobileMark benchmarks. “The content of BAPCo benchmarks are vigorously debated and cooperatively developed by BAPCo members according to a long and rigorous process,” the company said in an e-mailed statement. “As is the case with all BAPCo benchmarks, MobileMark 2007 was approved by BAPCo according to a democratic voting process similar to ones used by most industry work groups.”

Despite the criticism, many vendors are willing to tout the battery life from the Productivity test as their overall MobileMark score. See these offers from Hewlett-Packard Co., Lenovo Group Ltd., and Dell Inc.

Only Acer Inc. (download PDF here) identified its MobileMark time as a productivity score. Asus Inc., Apple Inc. and Toshiba Corp. didn’t mention MobileMark on their Web sites.

In late June, a class-action lawsuit was filed in U.S. District Court in San Jose, targeting Intel Corp. for, according to the San Jose Mercury News, “essentially rigging those tests to inflate the battery life of laptops powered by its chips.”

Intel denied the claims, and noted that the same law firm, Girard Gibbs of San Francisco, unsuccessfully filed a separate class-action lawsuit against Intel several years earlier, according to the Mercury News.

Intel also disputes the claim that the public is being misled. “Anyone who criticizes consumers’ intelligence when shopping for laptops is underestimating the consumers,” an Intel spokesman told the Mercury News.

Carol Hess-Nickels, director of marketing for business notebooks at HP, took the same line. “I’d say we are pretty pleased with the benchmarks used today,” she said in an interview last month several days before the lawsuit was filed. “I’ve not personally gotten complaints.”

HP claims business netbooks such as the Mini 2140 and the Mini 5101 can run up to eight hours, or a full business day, on an optional, extended battery.

Lenovo, which has claimed as long as 7.5 hours of battery life for its laptops on extended batteries, acknowledges there is a problem, however.

“We don’t really like the fact that something is supposed to get four hours and users routinely say, ‘We divide that number by two and that’s what we get,’” said Lenovo segment marketing manager David Critchley in an interview, also several days before the lawsuit’s filing.

Dell appears to agree with Lenovo. “Customers expect the advertised battery life to reflect the way they really use the product,” Ketan Pandya, head of AMD-based products at Dell, told Newsweek last month.

As a counterbalance, some magazine reviewers go overboard to turn off all of a laptop’s power-saving features, Critchley said, which is equally inaccurate. “We put a lot of time and effort into our power manager,” he said. “You’ll see some significant gains from the way we handle sub-components.”

AMD, which complained that MobileMark essentially discriminates against its chipsets because they are more graphically powerful than Intel’s, is all for reforming MobileMark.

In a blog entitled “There has to be a better way,” AMD suggests turning the widely used performance benchmark, 3DMark06, into “an active battery life test” that it argues would be a more accurate measure of average battery life.

Lenovo, although game, is more cautious. “If Dell, HP and Apple all said, ‘Yea, verily,’ Lenovo would be right there with them,” Critchley said.

Cold lithium batteries power the development of new energy automobiles and then identified the direction of

Friday, July 31st, 2009
From the beginning of July 1, the “new energy automobile production enterprises and the rules governing market access for their products,” the official start. A new rule has caused an uproar in the market: Prior to the voice of the highest automotive lithium batteries are included in the development of a view, not in the list of large-scale promotion. In other words, was also optimistic about the market, Buffett repeng of lithium batteries Latitude X300 battery, XPS M140 battery, XPS M1210 battery  for electric cars lose a nickel-hydrogen batteries in hybrid hands!
Has just enacted a new access system to the December 31, 2010 apply, with the National Development and Reform Commission published in 2007 compared to the standard, the letter of the standards set by the Department of new energy vehicles for the three technical phases of the fine products of.
The new access system for different types of new energy development and operation of motor vehicles to give a more clearly defined. “The access to the standard mark of China’s new energy into the acceleration period of the automobile industry.” Industry experts said.
What surprised the industry is a new regulation, “the use of lead-acid laptop battery  hybrid passenger cars, electric cars and electric commercial vehicles, and the use of nickel metal hydride hybrid-powered passenger cars were classified as mature view products.
A sudden, the market in an uproar: the voice of the highest previous car was the inclusion of lithium-ion battery development period, the list is not a large scale. In other words, was also optimistic about the market, Buffett repeng of lithium batteries for electric cars lose a nickel-hydrogen batteries DELL laptop battery ,  KD476 battery, TD347 battery in hybrid hands!
Department of Public Works letter why such a launch of new energy vehicle development road map? This road map will eventually lead to new energy sources can not be a readjustment of the industrial structure of China’s best “catalyst”? Can help China to catch the express train of the new energy of the realization of non-transcendence?
Who will lead the new energy automobiles
Nickel-metal hydride batteries and lithium battery, China’s new energy vehicles will be led by whom?
For consultants in the new energy automotive industry researcher Sheng Mao pointed out that the current driving force of new energy automobiles automotive lithium batteries Inspiron 9300 battery, Inspiron 9400 battery  have been the most promising development prospects, but the Department of Public Works this letter is not conducive to the development of a standard lithium cell vehicles across the country to promote universal access to further that this may be China’s new energy constraints of the overall development of the automobile industry.
Department of Public Works letter was optimistic about the nickel-metal hydride battery itself has a certain degree of short-board. China Electrotechnical Society dedicated electric vehicles, director of technical service center Commission Wang Tianshun also said that while China was rich in hydrogen storage materials, but the extraction technology is not high, poor battery consistency, technical problems, there has been no breakthrough, but the cost of nickel-hydrogen batteries Business Notebook NC6115 battery, Business Notebook nc6120 battery, Business Notebook nc6140 battery have been home high.
Energy in the last week of the new car after the introduction of access rules, China’s new energy industry of the largest lithium batteries, “Players” BYD reporters in the face of our interview, saying that “no comment.” But then, this reporter was informed that the exclusive, BYD is committed to the commercialization of electric vehicles has been quietly acceleration process. According to company executives informed sources, the price is expected to 30 million of the BYD E6 Electric Vehicle directory is to declare the country is expected to be listed at the end of this year, at the same time, another F3DM a dual-mode electric vehicle will also determine the 9 on sales to private consumers. “We will be in 13 major cities nationwide in sales, the DM model HP laptop battery , we entered the last year the Department of Public Works letter directory automobile production. At present, the main vehicle to invest in Mainland China, 800,000 have completed the building of capacity.”
Access around the new rules, the industry has formed two distinct voices of the debate:
The first one, represented by Lee Sheng-mao. He pointed out that under the new standards already listed BYD dual-mode electric vehicles, lithium batteries Pavilion dv6000 battery ,  Pavilion dv2000 battery, Pavilion dv4 battery are the automotive, although mass production, but only in approved areas, the scope of product sales, which significantly restricted their products comprehensive promotion. The Chang’an Jie Xun, Chery A5, FAW Benteng, General Grand Hyatt brand, and most other HEV cars are used in nickel-metal hydride batteries used in sales nationwide. Obviously, this kind of national decision-making to the state-owned car business, the Group of tilt.
The second expert opinion is that the new rules show that the country access to a more pragmatic attitude towards the decision-making.
In conjunction with the National Under-Secretary-General by Choi Dong-trees that “look at the new access rules on a more pragmatic national policies, in no hurry to act. Before we are all very optimistic about the lithium electricity, but a matter of fact, after a technological breakthrough development. Lithium definitely the need for a breakthrough in the country currently are not ripe for the promotion. and Ni-MH Compaq laptop battery  time is ripe for the promotion, the cost of nickel-hydrogen, hybrid performance to meet the basic needs of dynamic product mix significantly more mature. ”
It is reported that the release of the new standard for the new energy vehicle technology stage, is divided into the initial period, development period, the mature stage of the three different technologies. Means the product is still at an initial stage of fuel cell vehicles, hydrogen cars and dimethyl ether engine car. Period of product development including power lithium-ion batteries Presario R3000 battery , Presario V4000 battery for hybrid-powered passenger cars, commercial vehicles, as well as pure electric vehicles. Mature technology, the principle is the realization of the path clear, product technology and production technology is mature, industry-standard countries and the basic sound, you can enter the stage of the industrialization of products. The production of lead-acid battery hybrid passenger cars, electric cars and electric commercial vehicles.
Obviously, the products are mature faster, “the road.”
In this regard, Li Sheng-mao that “lithium-ion powered car, only in approved areas, the scope, duration and conditions of sale, the use of.” The new regulations will greatly affect the development of lithium batteries car speed, and to some extent, the impact of car prices on lithium battery research and development initiative of motor vehicles, lithium-ion battery is not conducive to the development of the automobile industry.
More promotion of Ni-MH battery
After an investigation, the reporter found, become the new darling of the nickel-metal hydride batteries, has a unique advantage.
It is reported that, at present, there is only one place in Guangdong, more than 100 Ni-MH batteries do the private sector. New energy-sensitive battery-making enterprises have already begun the distribution of nickel-hydrogen batteries as plans for the future.
Li Yuan and the Hong Kong Branch super in July last year on the signing of a joint venture agreement, co-funded the establishment of 50 million yuan in Hunan Branch Pa Power Battery Co., Ltd., in June this year, much to our Section 120 million yuan in cash to acquire electronic limited Changsha and Seoul liability company 100% ownership. Plans to invest in new sets of 48,000 nickel-hydrogen battery vehicle energy package, and a relatively substantial production capacity expansion, after the completion of Phase II expansion project will have an annual output of 60,000 sets of the vehicle’s nickel-hydrogen  Evo N600C battery capacity .
Compared with lithium, nickel-metal hydride battery is characterized by high security, it is not easy explosion.
Guotai Junan Securities Research on alternative energy expert Wang Zhen of the judge, with the introduction of the new access system, nickel-metal hydride battery is expected to accelerate industrial development, and related businesses due to limited production capacity, production still needs further observation, but such a listed company pre-or have a larger, very high valuation on the Ni-MH battery will be cautious about the stock.
“In the lithium iron phosphate Sony laptop battery technology is not yet mature, the Department of Public Works issued a letter of the new energy standards for motor vehicle access to the new Ni-MH battery also ushered in a major automotive development opportunities.” Vote in the new energy automotive industry consultant researcher Sheng-mao told reporters this. A few days ago, released a consultancy in the cast of “2009-2012 China Li-ion battery industry and prospects for investment analysis report,” the study shows that the current hybrid battery market share of 99% for nickel-hydrogen batteries VGP-BPS9/B battery , VGP-BPS9A battery , commercial representative of Toyota The Prius.
However, the objective point of view, Ni-MH battery, there are some “elbow Mount” in: refining technology is not mature enough, the cost is too high.
China Electrotechnical Society, according to electric vehicles designed, director of technical service center Commission presented王天顺, our country 10 years ago began to study the development of electric vehicles, but has been constrained by technology. Consistency is the biggest problem. Low-power battery pack can be, but as a hybrid, the major source of energy for electric vehicles is the need to make high-power battery packs do, the greater the power, the greater the difference.
The possibility of common prosperity
Industry experts believe that the new car as an emerging energy field, is becoming the world’s auto industry to catch up with China’s auto industry is a rare technology “leapfrogging” a good opportunity, so the development of comparative advantages of our Toshiba laptop battery  line. In fact, this reporter found in the survey, nickel-metal hydride batteries and lithium batteries have different advantages, in the future is entirely possible to achieve “common prosperity.”
Shun Securities analysts said the driving force for the future of lithium-ion batteries and nickel-hydrogen batteries is expected to achieve common prosperity, Toyota hybrid (HEV) in all of the use of nickel-hydrogen batteries, and lithium-ion power batteries for hybrid-electric plug ( PHEV), the two different application areas. Line in the choice of technology should not only attach importance to the advanced nature of technology, but also consider the success rate of commercialization.
In fact, China’s new energy industry development should be from the Japanese companies learn from the experience and learning.
July 2, Japanese media reported that Hitachi plans to invest 20 billion -300 billion yen (about ¥ 96 1 U.S. dollars) in 2015 for the current lithium-ion PA3178U-1BRS battery hybrid production capacity increased by about 70 times to reach 700,000 vehicles for the level of support. At present, Japan’s leading auto and battery companies have to invest in automotive lithium-ion power battery production line, to concentrate production in 2010-2011. Lithium-ion battery technology as the mainstream of the next line of no doubt.
This would be regarded as Japan’s new automotive research and development of energy has been quietly changing the direction. Nickel-metal hydride batteries in the world’s leading technology, the Japanese pay more attention to the development of lithium batteries PA3191U-1BRS battery , PA3191U-2BRS battery .
Nevertheless, Japan’s Panasonic and Sanyo have said that “lithium batteries also need to continue tackling issues such as security, so it still takes time to commercialize.”
In this regard, investment advisers in the new energy automotive industry researcher Sheng-mao believes that new energy sources for electric vehicles in recent years, the voices growing louder and louder, and lithium cell vehicles have been the most promising development prospects, therefore, all countries, as well as car manufacturers are to the development of lithium batteries as the car focus on the direction of Japan in this regard is as a new energy vehicles to focus on the development of strategic focus.
Sheng-mao said that China’s car prices and promote the battery business in addition to Ni-MH battery industry, the Government should look to more long-term investment of human and material resources to carry out research and development driving force for lithium batteries and fuel cells to maintain the technical follow-up for the occupation of a broader market of new energy to prepare. After all, the new energy vehicles to China with a rare start at the same time the international automobile industry the opportunity to miss this opportunity to once, the consequences would be disastrous.
The threshold of the new rules to improve the industry
In addition to the types of new energy vehicles have been divided, the new rules of access to another major significance is the threshold for the development of the industry, the new energy future based on the rule.
Access under the new rules, new energy, auto companies should be the National Development and Reform Commission announced the vehicle manufacturer and product notice vehicle manufacturers or modified types of commercial vehicle manufacturers; new car should be in accordance with the relevant provisions of the Investment Management to handle project approval or registration procedures.
In this regard, the research department of CITIC Securities analyst Li Chunbo car that new entrants into the business, must abide by the “automobile industry development policy,” the requirements of Development and Reform Commission reported that the approval of access to traditional automobile “birth allow card “, so a total investment of not less than 20 billion yuan. Would like to enter a new energy future, the ranks of the more difficult car.
Guotai Junan Wang Zhen alternative energy researchers believe that the new energy from the previous car’s development, production does not require the industry to now set the threshold, which has a definite progress. Car prices from R & D capability, quality, consistency, the new energy automotive industry has increased the threshold for a matter of fact. “The access rules of the lead-acid battery products PA3285U-3BRS battery , PA3331U-1BRS battery  are included in the mature product, and at present all over the country of production of lead-acid electric vehicles dotted the small business, and part of the local government has received permission to allow the local road. However, the size of the of view, these enterprises do not meet the threshold requirements. ”
Tao, deputy general manager of Chery Automobile said last week that “For a mature new energy automotive industry, product reliability and consistency are the most important, and to ensure that this point, it is necessary to carry out a large number of tests, vehicles plant and components must go through a long-term co-ordination and testing. “Therefore, the Department of Public Works letter of the rules governing the application of new energy automotive products is still at an initial stage or stages of the development of technical, need to submit after-sales service commitment, he said he was authorized .
SAIC and Chang are the person last week said he was in favor of the new energy automotive and product manufacturers access to the threshold “will be the beginning of the high.” Access to the promulgation of new rules, have been robbed of these new car-based energy companies,  PA3384U-1BRS battery , PA3395U-1BRS battery is extremely beneficial. This year, Beijing’s new energy auto base car new energy base in Chongqing have been established, Beijing Jianlong Group Heavy investment in “new car key components of energy” project in April 2009 set up a formal xiqing ,Tianjin of District. Wuhan Dongfeng Electric Vehicle Industrial Park was also unveiled in June. Followed by SAIC and its listed companies Shanghai Automotive (600,104) joint venture of Shanghai Automotive Technology Dresdner Limited (Dresdner Shanghai) also formally inaugurated the operations.
“In fact, the development of electric vehicles in terms of technology, SMEs have also have a lot of leading-edge technology.” China Electrotechnical Society dedicated electric vehicles director of the Center for Technical Services Committee told reporters王天顺, but the new access rules these smaller block on the outside.

How To Equalizing Battery Packs?

Friday, July 31st, 2009

Many battery packs are made up of individual battery cells. When batteries are purchased to be made into a pack it is a good idea to equalize the charge on the batteries before building the pack.

Equalizing the batteries is nothing more than ensuring the voltage on each cell is within a very close range at the same state of charge (i.e. fully charged).

If you do not equalize the batteries properly before building a pack, the charge and discharge cycles will be harder on some of the cells and will effectively shorten their life. Once a cell fails the entire pack will be weaker because of the one defunct cell.

There are a couple of ways to equalize a set of batteries:

  • The first way is to connect the set that will go in the pack in a parallel configuration. Leave them in this state for at least 24 hours. The cells that have a higher charge will charge the ones with a lower charge and they will all equalize.
  • The second way is to put them in a parallel configuration again, but charge them together at 1.4V, current limited to total capacity divided by 40 (e.g. 3000mAh/40 => 75mA current limit). This may be faster than equalizing via the previously mentioned parallel method and you will start with a charged set of cells when you make the pack. Be sure to have an accurate voltmeter to check the charge voltage.

U.S. hydrogen fuel cell technology development - from the fossil energy system to a hydrogen energy system and the diversification of a major conversion

Energy system from fossil to hydrogen as the carrier to the new system and the diversification of energy conversion, even though seemingly incredible, but it is not unprecedented. Countries in the world until the mid-19th century is still based on its energy system as the main means of transport livestock to wood heating and cooking. Today the formation of coal, oil and gas fossil energy systems and transportation fuel and electricity energy is everywhere-dell xps m140 battery,dell xps m1210 battery, dell 6y270 battery, it has been difficult to distinguish between functions of a modern society out.

It may be in the current energy system to the next generation of the edge of the conversion and diversification. Today, including the United States, Japan and other developed countries, as well as China, Brazil and India, strong economic growth in developing countries and the international community, a strong awareness of hydrogen as a future clean and sustainable energy system, a key, it is important component. Future hydrogen energy system is an important characteristic of hydrogen as a fixed power supply, transportation, industrial and residential, commercial use of an energy carrier, hydrogen will become a new energy system for the global economy, social development is not used exhaustible energy resources.

Because hydrogen is an energy carrier, is currently in production, storage, transport and use of such areas as technology development is still in the stage of technical maturity, hydrogen will be mainly from the acquisition of cleaner production technology. Hydrogen from electrolysis of renewable energy access, or from the use of fossil fuel carbon sequestration through the restructuring process of the solution after the acquisition. Hydrogen can be like oil, natural gas and other fossil energy is effectively stored, truck or pipeline transport. When the hydrogen for fuel cells, turbine or generator to produce electricity, it is the water main by-product.

Highly concerned about the United States of hydrogen and fuel cell technology development, its purpose is: In the short term, fossil energy use due to a large number of serious greenhouse gas emissions by the enormous international pressure to bear, so far the U.S. government have not signed the United Nations issued in 1997 “Kyoto Protocol” developed countries should shoulder the provisions of the emission reduction obligations, the Bush administration has recently made many times will not sign the document, the United States and the strengthening of hydrogen fuel cell technology development is to show a positive attitude. Another consideration is the hope that the United States through high-tech development, create more employment opportunities, the country’s industrial structure adjustment and upgrade their products in the international market competitiveness and to increase the current energy security and reliability of electricity supply needs. In the long run, as the world’s mineral resources, especially oil resources will become depleted, there is an urgent need to find a new energy resources or products dell 75uyf battery,dell c1295 battery,dell gd761 battery, to the next generation energy system for the conversion and diversification of the technical preparations to do the full system and a long time accumulation of operating experience.

Generally speaking, the development and utilization of hydrogen and fuel cell technology has many advantages:

• Can make use of the United States a large number of resources and different production methods, means hydrogen fuel;
• Reduce demand for imported oil, especially in the transport of oil resources required;
• Fuel cell can power transmission grid system is not able to meet the supply, the emergency start to fill the shortage of electricity supply, electricity supply has played the role of the peak;
• Can significantly improve air quality in the United States, the atmosphere, so that vehicle exhaust and clean use of fossil fuels in electricity production system is close to zero emissions.

Speaking from principle, hydrogen fuel cell is electrolysis in reverse reaction, the air in the mixture of hydrogen and oxygen to produce catalytic electrochemical reaction current, heat and pure drinking water. In addition to the characteristics of zero emissions, the fuel cell can be higher than the internal combustion engine 2 to 3 times the efficiency of the fuel cell power generation makes it the ability to work to obtain a wide range of applications, including: portable (50 ~ 100 watts) and the fixed station ( 1 ~ 200 MW). Although fuel cells have the service in all aspects of the economic potential of the area, but today they are in terms of price than the internal combustion engine is also relatively expensive, further development of the future will be to improve reliability and reduce costs in order to have economic competitiveness.

1. To hydrogen as a carrier of energy conversion system and the diversification of energy supply is a strategic choice

(1) the United States energy consumption, demand forecast
(2) U.S. oil production, consumption
(3) the United States transport energy strategy
(4) the development of fuel cell technology the United States road map

To this end, the United States the development of fuel cell technology is the basic road map:

• In 2015 to develop fuel cell technology can be carried out after the success of business kd476 decision-making;
• 2020, fuel cell vehicles is still in development stage, but during that time, in essence, the success of the technology not have any impact on the development of a large number of imported oil this trend;
• After 2020 may reduce the oil imports and oil fields in the consumption of transport;
• If the 2040 large-scale use of fuel cell vehicles a breakthrough, then the amount of light oil per day can reduce the 11 million barrels, equivalent to the amount of U.S. oil imports.

① Solid State Energy Conversion Alliance (SECA) program

② Department of Energy and the American Automobile Association (Freedom CAR) plans to

In short, as a result of fuel cell technology and energy efficiency, renewable energy technology development and wide application of strong, such technological breakthroughs and large-scale application in a certain extent, a significant reduction in the production and emission of greenhouse gases. However, despite the fuel cell has the potential of national interests, but it is in the current technological development, the need for capital investment in high-intensity running and long-term access to technical and economic indicators of the accumulation of these factors severely limits its commercial pre-set process. Based on this, the current U.S. government funding, technology development, testing fuel cell technology research with commercial applications, such as the value of the model will continue to play an important role.

2. The source of hydrogen

Long-term strategy for the United States is: the future of fuel cells required for the vast majority of hydrogen from renewable energy resources in the production of access. For example, the use of wind and solar energy dell 75uyf battery,dell c1295 battery,dell gd761 battery converter steelmaking technology of water electrolysis to obtain hydrogen; the use of sunlight or light from biomass catalytic hydrogen production methods; nuclear energy (using thermo-chemical process or electrolysis) is also an optional way. Make use of these methods as a result of increased diversification of energy sources, can significantly improve the U.S. national energy security.

The near term, hydrogen from fossil fuels will be able to (such as petroleum and natural gas) or the use of electrolysis to obtain the solution. Existing projects in the United States arrangements, the main purpose of these processes is to improve the cost and efficiency. Electrolytic method of producing hydrogen in the near future (from the distribution point of view) can be achieved, but its drawback is that use of the existing methods of electricity production, will not be able to produce energy, the environment in Iraq the ultimate efficiency; carbon dioxide absorption and to deal with the problems once they become reality can be used in this way will be from fossil fuels in the production of hydrogen, which will minimize the large number of greenhouse gas emissions.

International Co-City Japan and the United States reaction to the purchase of

According to overseas media reports, the international market price of cobalt in 2006 turned into the fall, and in February, after the bottom fell, with the strong growth in market demand, supply shortages, from the beginning of March the price rise become more evident. Strategic metals markets in Europe Rotterdam warehouse delivery for 99.8% grade premium grade cobalt, in February of this year fell to 12.75 ~ 13.25 U.S. dollars per pound, the has been increased to more than 15 U.S. dollars, 99.3 percent cobalt grade premium from 11.5 ~ 11.7 U.S. dollars rose to 13.75 ~ 14.5 U.S. dollars. At the same time, the actual current senior U.S. spot price of cobalt increased to 14.25 U.S. dollars per pound, the Russian Co-99.3%-level export price rose to 13.25 U.S. dollars, Zambia delivery price of 13.25 U.S. dollars, the Australian company BHP reported in Asia, Europe and North America, prices rose to 14 U.S. dollars.

According to industry estimates, global cobalt demand in 2006 up to 65,000 tons in 2007 to more than 70,000 tons. The main reason is the world’s airline industry, land-based gas turbine power stations and military arms of the active industrial production led to a marked increase in the consumption-cobalt alloy. It is understood that China will in the next 10 years to buy 180 billion U.S. dollars worth of power generation equipment, no doubt will lead to increased consumption of cobalt. The supply side, despite an ample supply of cobalt raw materials, but a serious shortage of refined cobalt production capacity. In this case, even if the capacity of refining cobalt production at full capacity, it is estimated that the market is still a shortage of refined cobalt supply and demand of 3000 tons. For this reason some people in the industry predicted that the end of the year for sustainable high-quality cobalt price climbed to 30 U.S. dollars per pound. Also has the trading community that the recent price of cobalt can be up to 16 ~ 18 dollars, because a large number of new cobalt smelting dell xps m140 battery,dell xps m1210 battery, dell 6y270 battery capacity by 2007 difficult to put into operation.

In addition, Russia Krasnoyarsk Connolly recently reported 99.3% grade for the class of cobalt base price also increased to 11.85 U.S. dollars per pound, but the company’s actual sales in the open market price of more than 13 U.S. dollars. The company is only a very small amount of a selective buyer of the company, and along with the revitalization of Russia’s aviation industry, tend to increase consumption of cobalt, it is estimated that the future will tend to decline in the export of cobalt.

Due to the rapid rebound in the international prices of cobalt alloys, as well as Japan and the chemical processing industry demand, some consumers worry about the future, Japan will further increase prices even higher, so they choose to move into the spot market to buy cobalt, or even at all costs. Japanese imports in December last year the spot price of cobalt 99.8% level has been increased to 16 ~ 17 U.S. dollars per pound, although in February this year, 1 to drop slightly, but the recent re-pricing of imports rebounded to 14 U.S. dollars per pound CIF. According to Japanese traders said that the Japanese battery industry accounted for about cobalt cobalt consumption to 60% of the total demand, and the industry under the forward contracts are usually imported cobalt was still adequate inventory, so buy on the spot market is currently little interest in cobalt.

At the same time, U.S. consumers to buy cobalt is also very active, especially in the spot dell kd476 market imports from Russia. However, 99.3 percent of Russia’s supply of cobalt-level is very scarce, and even the recent delivery of cobalt has been sold out. Russia supplies the current level of 99.3% cobalt prices and the market price of 99.8% of the difference in class is gradually shrinking, and even less than 1 U.S. dollars per pound. Some consumers are also the same by the United States the annual import turnover of the contract, so from the spot market is not buying.

Scientists invented the fuel cell enzyme

Oxford University scientists have invented a device to provide an impetus to the electronics of the fuel cell enzyme, which is the battery consumption of atmospheric oxygen and hydrogen. The enzyme used is from the natural world for the use of hydrogen metabolism in the isolated bacteria. The characteristics of this enzyme is a highly selective, able to put up with the traditional fuel cell catalysts has a poisoning effect of the gases, such as carbon monoxide and hydrogen sulfide. The researchers said: As a result of this enzyme to the growth, so compared to other hydrogen fuel cells by use of expensive platinum catalyst is a cheap, renewable battery.

By Professor Fraser Armstrong led the design of the research group including the fuel cell has two electrodes coated with the enzyme. They are filled with normal air, and add a small amount of hydrogen in the glass tank. As the catalyst selectivity and tolerability, so the gas can be mixed without the need for expensive fuel separation membrane.

Armstrong said: The study resulted in greater fuel-cell applications of space, as has been the cost of fuel cell applications are the main issues, but can not guarantee that the source of cleaner fuel and the need for real-time power.

Solar cell production capacity in China in 2007 accounted for 16.7 percent of global

According to China’s Taiwan, “Industrial Technology Research Institute” under the Optical Technology Center (PVTC) is expected to the end of 2007, the global solar cell production capacity is expected to reach 48,000 kilowatts (GW), of which the mainland will reach 16.7 percent global market dell latitude d830 battery,dell latitude x300 battery share, more than Taiwan, about 10%. PVTC Taiwan in 2006 is expected to remain slightly ahead of the mainland.

PVTC expects Suntech China, Nanjing PV (Nanjing PV) solar cell manufacturing plant the two together will reach about 12.5%, if the other new entrants into the mainland is expected to reach a global market share of 16.7%, far exceeding Taiwan manufacturers.

It is worth mentioning is that Suntech an annual production capacity of 2006 is expected to more than 300 megawatts (MW), expected from the world’s eighth in 2005 jumped to fourth place, behind Japan’s Sharp (Sharp), Germany’s Q - Cells and Japan’s Kyocera (Kyocera). PVTC pointed out that the positive into polysilicon production and a huge domestic market demand for solar cell production capacity in China a major factor in the rapid growth.

China’s renewable energy policy incentives, the expansion of growth in demand for solar industry

In new renewable energy policy incentives, China’s domestic supply chain in all areas toward the expansion of solar power in the direction - of polysilicon feedstock, wafer, cell and module. Investment bank Piper Jaffray analyst Jesse Pichel said in a report, China last month promulgated a renewable energy project involves 3.5 billion U.S. dollars of investment, designed in 2010 in the domestic solar power generation capacity to 500 megawatts. China also plans to solar power by 2020 will amount to 3,000 megawatts in 2050 to 6,000 megawatts.

“In China, promulgated in February of renewable energy plan under the impetus of China’s solar energy needs are expected to be substantial growth over the next few years.” He said, “apart from less than 200 dollars a month in labor costs, China’s solar energy company may also be lower because the cost of management, research and development costs and external costs to benefit. ”

According to the analyst, by 2008, China’s total module production capacity from 450 megawatts (MW) increased to 1,200 MW, the domestic solar cell production capacity increased from the current 200MW to 1,200 MW. 2005 China wafer capacity of 100MW, is expected to grow in 2008 to around 800MW, mainly from the signing of polysilicon supply, as well as contracts for the supply of a large number of polyethylene.

He said that China’s solar manufacturing equipment industry will also expand. At present, the three Chinese polysilicon manufacturers monopolized the domestic dell latitude d800 battery,dell latitude d810 battery,dell latitude d820 battery market, but it is still a shortage of supply of material.

“By 2007, Sichuan Xinguang silicon industry is still at an early stage of production and construction, planned in 2008 to 1,250 tons of annual production,” Pichel said, “LSCS current annual capacity of 300 tons, production capacity in 2007 reached 1,000 tons. Another year the current ESM about 100 tons of production capacity. “polysilicon high price to 200 U.S. dollars per kg, most solar manufacturers can accept the OEM price is about 170 U.S. dollars per kilogram.

By the end of 2005, China’s light industry in China’s famous brand products 40% of brand-name products, many world-class product quality level.

New energy into the energy development will focus on

Sustainable Development Strategy of the Chinese Academy of Sciences, honorary head of the group not long ago, said Niu Wenyuan, the world’s energy development is accelerated from the “carbon-based energy” to “hydrogen-based energy” forward, “China’s energy strategy is not only a big topic, but also the world’s largest energy strategy proposition. ”

In the newly published by the People’s Publishing House “Who can drive in China - the world’s energy crisis and China’s strategy of” one book, said Niu Wenyuan, a breakthrough from the first “Light-harvesting protein” genes of biological photosynthetic energy efficient chip-to-large-capacity hydrogen fuel cells, hydrogen-based energy from the acquisition and transmission to the “Space Spider” energy network weaving, from -3 isotope helium surface on the acquisition and preparation of energy into controlled thermonuclear fusion, such as consumption, these new energy will gradually energy development path, “the central stage.”

“Energy has become China’s future development, one of the major bottlenecks.” Niu Wenyuan said that China’s energy strategy, on the one hand to firmly grasp the universal energy-saving, industry-wide energy saving, energy-saving society as a whole, “a key element,” not to relax On the other hand, did not slacken our efforts for the deepening of opening up new energy. “As an energy consuming country dell latitude d600 battery,dell latitude d610 battery,dell latitude d620 battery, China should be at the same time the consumption of traditional energy sources, energy development as soon as possible the next generation to take active steps to plan.”

According to authoritative statistics, Chinese people can be a one-time energy production per capita, compared with the world, with lower values. At the same time, the intensification of China’s energy level is still relatively low, a waste of a very serious situation. These data show that, on the one hand, China’s rapid industrialization and urbanization development, requires a large amount of energy to support, on the other hand, China’s energy-saving potential is very great.
