Electric vehicles use Lithium-ion battery to develop their technology
Currently, lithium-ion batteries use copper as the anode, and aluminum as the cathode; lithium salt electrolyte is typical; separation layer is mainly PP.
Frost & Sullivan predicts that in 2008 to 2016, the electric vehicle battery material market revenue’s compound annual growth rate will reach 125%, lithium battery anode materials will yield 134% annual, yield lithium separation layer will be 129% per year, lithium electrolyte and additives will yield 136% annual.
Battery system’s security is one key factor of the public acceptance of electric vehicles, this is because when the car is running, it will generate heat which leads chemical reactions, further explode. Therefore, the insulation materials and thermal management system for electric vehicles is the key to the promotion of electric vehicles. Lithium-ion batteries because of high energy density, the future is expected to replace the nickel-metal hydride batteries used in hybrid and electric vehicles.
In the next a few years, the development of electric vehicle battery industry will be subject to the following factors: industry, infrastructure development, the product of globalization, product safety, performance and cost trade-off, with suppliers and end-user relationship and so on. In addition, with the technology, the battery charging time will be significantly shortened travel distance will be longer on one charge, the battery energy will be greater.
It was reported that in 2009, the global total has about 50 chemical materials electric car battery manufacturer, mainly in Europe and America. These enterprises mainly for battery manufacturers and battery assemblers and automotive OEM supplied products. At present, the electric vehicle battery market in the value chain by the chemical material suppliers, battery manufacturers, battery pack composed of business and automotive OEM business. Vertically integrated value chain will become one of the industry’s future trends.
From the global perspective, the current Asia (mainly Japan, South Korea, China) is a major market for battery-chemical materials, its market share to over 80% of the world. Meanwhile, the European market is growing rapidly and will become an important market for battery chemical materials. Fluctuating oil prices, urbanization and changes in energy demand, government incentives for new energy and battery technology, battery electric vehicles will promote the development of chemical materials market.
