902030 polymer battery.Development status of lithium batteries

　　In recent years, policies related to lithium batteries have been gradually introduced, promoting the establishment of upstream and downstream enterprises in the industry like mushrooms after rain. Lithium batteries are mainly composed of positive electrode materials, negative electrode materials, separators, and electrolytes. Positive electrode materials account for over 40% of the total cost of lithium batteries, and the performance of positive electrode materials directly affects various performance indicators of lithium batteries. Therefore, lithium positive electrode materials occupy a core position in lithium batteries.

　　Currently, lithium-ion battery cathode materials that have been commercialized include lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, and ternary materials.

　　With the rapid development of China's economy and the increasing demand for new battery materials, coupled with the strong demand for new, efficient, and environmentally friendly battery materials in products such as mobile phones, laptops, digital cameras, cameras, and automobiles, the market for new battery materials in China will continue to expand. Lithium batteries, as the future development direction of batteries, have a promising market for positive electrode materials. Meanwhile, the promotion of 3G mobile phones and the large-scale commercialization of new energy vehicles will bring new opportunities for lithium battery positive electrode materials.

　　Although lithium battery cathode materials have a broad market, the prospects are very optimistic. However, there are still certain technical bottlenecks in the positive electrode material of lithium batteries, especially its advantages of high capacitance and strong safety performance have not been fully utilized.

　　In fact, in the field of lithium battery positive electrode materials, any minor technological innovation may trigger a new round of market expansion. Chinese enterprises should strengthen the research and development of key technologies for positive electrode materials, achieve an international leading position, enhance core competitiveness, and gain an advantage in international competition.
