The development trend of lithium battery cathode material industry

Source: 2020 - 04 - 20 transgress hits: time is a major component of the lithium battery electrolyte, insulation material, the positive anode materials and electrolyte. The successful development and application of the anode materials mainly include lithium cobalt oxide, lithium iron phosphate, nickel, cobalt, manganese acid lithium manganese acid lithium ( NCM) , aluminum nickel and cobalt acid lithium ( NCA) Such as ternary material. Lithium battery cathode material 1. Excess low-end products, high-end product shortage due to the lithium battery cathode material production capacity in China mainly concentrated in the low-end products, high-performance ternary materials such as high-end products production capacity is still insufficient. Therefore, industry as a whole in the stage of the glut of lithium-ion battery anode materials, the future demand for power battery is the main driving force. On the product distribution, excess production capacity of low end products, high-end products in short supply. The development trend of lithium battery cathode material industry 1. Lithium battery was listed in the first batch of key new materials to demonstrate the application directory on July 14, 2017, the Ministry of Industry and Information Technology released the first batch of key new materials to demonstrate the application guidance catalogue. Guidance catalogue involved in the new materials in the field of new energy has 4 kinds, including high performance lithium battery diaphragm, NMC lithium ternary material, cathode materials, high purity lithium fluoride phosphate crystal materials. 2, industry fast development, the formation of industrial base because of China's production of lithium battery cathode material for lithium, cobalt, manganese, nickel and other metal resources are rich, consumer electronics, new energy vehicles such as lithium battery downstream application market is expanding fast. High concentration of lithium anode materials industry in China, and formed the Beijing and tianjin, the middle and lower reaches of the Yangtze river, south China three lithium anode materials industrial base. 3. Downstream industry to drive industry growth in the lithium battery and its downstream industry rapid development, under the drive of lithium battery cathode material has developed rapidly. Power lithium battery as the key components of the electric car, is affects the automobile performance, cost and user experience of one of the key components. It is also the largest vehicle cost ratio of components, half of the cost of the vehicle. In terms of segmentation, cathode materials, anode materials, diaphragm and electrolyte four key materials costs more than 80% of the cost of battery. Among them, the cathode material cost accounts for about 40% of the total cost of the lithium ion battery. 4. Continuous technological innovation, yunnan province, kunming university of science and technology key laboratory of advanced battery materials mainly research on lithium ion battery and key materials, development of lithium ion anode materials, three yuan battery preparation and management of the core technology. Core - 'much starker choices-and graver consequences-in' Shell structure with long life and high nickel anode materials development achieved a new breakthrough, significantly improve the cycle stability of the high nickel anode materials. Soft package lithium battery soft package of lithium ion battery is made through the stack, so under the same capacity density, they are thinner, lighter. Similarly, soft package battery can also be customized according to the requirements of the app, the size of the mobile phone battery from us to the application of new energy vehicles. Soft package battery mobile devices has been the industry's first choice, but in automotive applications, due to its size controllable also brought to the attention of the brand, especially for a plug-in hybrid car, when considering vehicle layout and weight, soft package on the size of battery advantages more apparent. Square square lithium-ion batteries lithium batteries more flexible, can according to the specific needs of customized products. Therefore, size is differ, there is no definite standard cylindrical battery, divided into both manufacturing process and application standards. But because of its high flexibility, in the early days of the new energy vehicles have been used for a long time. Car companies can customize according to the requirements of vehicle square size batteries, not restricted by cylindrical battery standard. Batteries are square is regarded as the most suitable battery design of the application of new energy vehicles
