Development Trend of Lithium-ion Battery Cathode Material Industry

Important components of lithium-ion batteries include electrolyte, separator materials, cathode and anode materials, electrolyte, and so on. Currently, the positive electrode materials successfully developed and applied mainly include ternary materials such as lithium cobalt oxide, lithium iron phosphate, lithium manganate, lithium nickel cobalt manganate (NCM), and lithium nickel cobalt aluminate (NCA). Lithium-ion battery cathode materials 1. Excessive low-end products and shortage of high-end products As the production capacity of lithium-ion battery cathode materials in my country is mainly concentrated in low-end products, the production capacity of some high-end products such as high-performance ternary materials is still insufficient. Therefore, the lithium cathode material industry as a whole is in a stage of oversupply, and the important driving force in the future is the increase in demand for power lithium batteries. In terms of product distribution, the output of low-end products is surplus, and the supply of high-end products is in short supply. The development trend of lithium-ion battery cathode material industry 1. Lithium-ion batteries are included in the first batch of key new material application demonstration catalogues. On July 14, 2017, the Ministry of Industry and Information Technology announced the 'first batch of key new material application demonstration guidance catalogues' '. There are 4 kinds of new materials in the guide catalog involving the field of new energy, including high-performance lithium-ion battery separators, NMC lithium ternary materials, cathode materials, and high-purity lithium hexafluorophosphate crystal materials. 2. The industry develops rapidly and forms an industrial foundation. As my country is rich in metal resources such as lithium, cobalt, manganese, and nickel required for the production of lithium-ion battery cathode materials, the downstream application market for lithium-ion batteries such as consumer electronics and new energy vehicles is expanding rapidly. my country's lithium anode material industry is highly concentrated, forming three major lithium anode material industry bases in Beijing-Tianjin, the middle and lower reaches of the Yangtze River, and South China. 3. The development of downstream industries drives up the industry. Driven by the rapid development of lithium-ion batteries and their downstream industries, lithium-ion battery cathode materials have developed rapidly. As a key component of electric vehicles, power lithium-ion batteries are one of the key components that affect vehicle performance, cost and user experience. It is also the component that accounts for the largest proportion of the cost of the entire vehicle, accounting for half of the cost of the entire vehicle. In terms of subdivision, the cost of the four key materials of positive electrode material, negative electrode material, separator and electrolyte accounted for more than 80% of the battery cost. Among them, the cost of anode materials accounts for about 40% of the total cost of lithium-ion batteries. 4. Continuous technological innovation The Key Laboratory of Advanced Battery Materials of Yunnan Province, Kunming University of Science and Technology, conducts research on lithium-ion batteries and key materials, and develops core technologies such as lithium-ion ternary cathode materials, battery preparation and management. Since the 13th Five-Year Plan, new breakthroughs have been made in the development of long-life high-nickel anode materials for core-shell structures, which significantly improved the cycle stability of high-nickel anode materials. Soft-pack lithium-ion batteries Soft-pack lithium-ion batteries are made by stacking, so they are thinner and lighter with the same capacity density. Similarly, the soft pack battery can also be customized according to the needs of the app, from the size of our mobile phone battery to the application of new energy vehicles. Soft pack batteries have always been the first choice for mobile devices in the industry, but in automotive applications, they are also valued by car brands due to their size controllability, especially with regard to plug-in hybrid vehicles. When considering vehicle layout and weight, soft pack batteries The advantages of batteries in size are more obvious. Square lithium-ion batteries Square lithium-ion batteries are more flexible and can be customized according to the specific needs of the product. Therefore, the size is different, and there is currently no clear standard to classify cylindrical batteries, whether it is the manufacturing process or the application standard. However, due to its high flexibility, it has been used for a long time in early new energy vehicles. Automobile companies can customize the size of the prismatic battery according to the requirements of the vehicle model, without being restricted by the cylindrical battery standard. The square battery is also considered to be the most suitable battery design statement for new energy vehicle applications: Some pictures and content of the articles published on this site are from the Internet.
