The gap between technology and making a profound impact on the industrialization of the industry market battery
Saturday, October 31st, 2009We thought, what is the driving force of development in the farm industry? We believe that whenever the application of new materials, so that battery performance has been a qualitative leap, each anode and cathode and electrolyte materials has also contributed to improving the quality of the battery will some margin improvement.
History of the battery, there is a history of materials, technological progress. Quantitative improvement of the technology to make the battery, the invention of new materials to promote a qualitative change in the battery. One can expect that the use of components containing conductive materials of lithium (ionic compounds, polymers) as electrode material is the best choice for high-energy batteries, as well as multi-Lithium element composed of ions found necessary materials technologies continue to advance.
Strengthening capacity for storing energy, improve energy density, which has always been the battery technology continues to develop the concept of one of the most direct. However, the person is not perfect yet, especially for high power and high energy is hard to get. In addition, we find that different products have different needs from the battery.
Thus, the development of battery materials is also diverse.
Comparison of the aspect of performance, security, price, life must be taken into account are the indicators to determine if certain types of batteries widely used. Because battery lithium-ion battery provides superior performance, for different cathode materials Li-Ion batteries to meet the cost differences in demand for different market applications, therefore, the formation of lithium-ion batteries for other types of cells almost completely replaced the trend.
Well, we feel that the work of manufacturing battery intensive, but the industry chain of the battery point of view, is also a high technological content, particularly in the treatment of extraction resources and preparation materials for the cell more involved in materials science. With icons lead-acid batteries, nickel-hydride batteries, metal, lithium-ion battery process of manufacturing the main link, we have emphasized the development orientation of the household battery industry and technical bottlenecks .
Industrialization of the battery, China and Japan, there is a considerable gap between the United States, which may eventually be reflected in the gap of the materials technology of industrialization between nationals and foreigners. In our opinion, to rely on imports of battery materials, small-scale manufacturing of individual cells are mature, but even if the materials of the stack to solve the problem, high capacity battery design and power manufacturing continues to face many problems, which is the electric vehicle battery technology to power requires a breakthrough in technical difficulty.
In terms of business development of China’s transformation battery, lithium-ion battery industry competitive in the market largely depends on the accumulation of long-term development of technology, rather than investment pure capital, and even the materials of lithium batteries have strong technical barriers, the small sub-leaders of industry who are mostly early entry into the industry. However, the small-scale lithium-ion battery business and technical level is very low, the influx of a large number of small players that trade margins to decline rapidly.
