U.S. shares of Dow Kodam Dow 22 company, announced that it will cooperate with the French Dassault enterprise group, production of electric cars and hybrid car batteries.
The company said in a statement that it had reached a preliminary with dassault cooperation agreement. Board member Heinz Haller, said: “This strategic cooperation and Dassault shows the company to accelerate Dow Kodam vehicle battery systems for the determination of supply and market expansion.”

In fact, the two companies started from 2008, to develop called “clean cell” lithium-ion battery technology.

Development of clean automobile energy sources has become a developing trend in the automotive industry. Motor Show held in Frankfurt, Germany, the German Volkswagen, Ford and other auto giants the United States have demonstrated their next generation of electric cars or hybrids.

      We learn that Philips X520 may be on the 7th (AAA) batteries to power mobile phones continued to this technology, is a self-Israel company Techtium developed BackuPower (backup power) technology, only 7 standard (AAA) can solve the urgent needs of the power of mobile telephony. In addition, it can identify and use a variety of different types of 7 (AAA) batteries such as alkaline, nickel-hydride batteries, metal in the machine, you can get an extra 3 hours of conversation. In addition, if you use the 7 (AAA) battery is rechargeable, then when charging for cell phones, cell phones and rechargeable batteries 7 (AAA) batteries can be charged. Under normal circumstances, the energy consumption the Philips X520 phone is also very durable, the longest standby time of 720 hours, the longest talk time of 480 minutes. This unique feature, for those who travel Business Travel, fashionable young dating Travel, provided the most reliable protection.

      Fashion Technology inclusive
     
      Advanced BackuPower (backup power) technology, to the X520 first in the world is more subject to problems phone the first wife of the fuselage cell battery, and integrated technology in creative ways and appearances elegant standby power to melt together. Once without electricity, and spend a few dollars in the street on hand to buy two alkaline battery No. 7, your phone can continue to use. Secondly, it is an ultra-chic-thin mobile phone, using a candy bar design, the overall look of ivory white, black and other colors such as crystal, cell phones were all fairly technological border surrounded by a sense of black, so that the entire mobile phone looks full of jump-like style. The rounded edges and smooth lines, so that the sense of excellent grip fashion sense seamless touch. It is commendable that the lower fuselage to the resting place on the 7th (AAA) batteries and well designed, built-in smart-slot design, beautiful appearance and a mobile phone perfect blend of power utility. Battery Warehouse does not affect the general appearance, near the warehouse is equipped with ornaments cover the use of chance as a “key” to open and close, rather original.

      Meanwhile, Philips X520 is a manifestation of simplicity and wisdom, is wonderful, you have the perfect life partner. It is equipped with a 2.0-inch 260,000 color TFT screen also has a wealth of entertainment features, built-in camera 2 million pixels at any moment can be photographed with the happy moment yet. Secondly, comes with an MP3 music player and FM radio and supports EDGE high Internet access speed, stereo Bluetooth and 2GB maximum capacity of the microSD expansion card, etc.. Never power-off plus a rich multimedia entertainment, Philips X520 Tour quickly bring you an infinite world.

     
      The first mobile phone in the world invented in 1973 by Martin Cooper after 20 years of rapid development of mobile phones for people’s lives upside down. In addition to the basic functions of the phone, the new phone can also be used to send and receive email play games, email and short messages, but also the Internet, take pictures and even watch movies, This is the original inventor of mobile phones beyond expectations. Today, Philips Cordless stamina and dedication of the X520, in the absence of abandoned cables plugged in for recharging, while the (General 7 AAA) batteries in the capacity of storage, mobile phones. This has created the myth of the life of mobile unlimited, based on the history of mobile phones a shot deep.

The advantages of lithium-ion dell laptop battery can

We have always said that the lithium-ion batteries are for the superiority of the traditional nickel-cadmium batteries (Ni / Cd) and nickel-metal hydride battery (Ni / MH) in terms of the. Then, lithium-ion battery good What went wrong?

(1) high voltage

(2) than the energy of large

(3) Long cycle life

(4) low self-discharge rate

(5) No memory effect

(6) non-polluting

The following is a nickel-cadmium, nickel hydrogen, lithium-ion battery performance comparison:

Lithium-ion battery Working Principle

Everyone already know that lithium-ion dell inspiron 510m battery cathode materials are lithium cobalt oxide, are carbon negative electrode.

Lithium-ion battery working principle refers to the principle of charging and discharging. When charging batteries, the batteries have a lithium-ion cathode generation, after generation of lithium-ion electrolyte to the anode exercise. As the carbon anode was layered structure, it has a lot of microporous, the arrival of Li-ion on the anode embedded in the porous carbon layer, the embedded lithium-ion more the higher the charge capacity.

Similarly, when the battery discharge (that is, we use the process of the battery), embedded in the carbon anode in lithium-ion layer extrusion, and sports back to cathode. Back to cathode of lithium-ion more higher discharge capacity. What we normally refer to the battery capacity is the discharge capacity.

Is not difficult to see, in the lithium-ion battery charge and discharge process, lithium-ion at the anode from the cathode → Sports → cathode status. If we take the lithium-ion battery Saying for a rocking chair, rocking chair at the two ends of the bipolar battery, and lithium-ion as the best athlete in the running back and forth at the two ends of a rocking chair. Therefore, the experts gave a lithium-ion inspiron 600m battery lovely name rocking chair batteries.

Lithium-ion battery assembly process

Lithium-ion battery technology is very stringent, complex and here only a brief one of several major processes.

(1) Pulping

Use of specialized solvents and adhesives in powder form with the negative electrode active material is mixed, with high-speed mixing evenly, the paste made of the positive and negative material.

(2) coating

Will be made from pulp evenly coating the surface of the metal foil and drying, respectively, a pole piece made of positive and negative.

(3) assembly

By cathode film - divide - negative film - diaphragm placed the order from top to bottom, the battery made by winding a very core, then injected into the electrolyte, sealing and other process, namely the completion of the battery assembly process, the system into a finished battery.

(4) into

With a dedicated battery charging and discharging equipment for finished battery charge and discharge test, for each battery are tested only selected qualified latitude d500 battery products to be manufactured.
