What are the factors affecting my country's lithium battery cathode material industry

1) Included in the first batch of key new materials use demonstration guidance catalogue On July 14, 2017, the Ministry of Industry and Information Technology of the People's Republic of China announced the 'Key New Materials First Batch Use Demonstration Guidance Catalog'. The 'Guide Catalog' touches on 4 new materials in the field of new energy, including high-performance lithium battery separators, lithium nickel cobalt manganate ternary materials, anode materials, and high-purity crystal lithium hexafluorophosphate materials. (2) The rapid development of industry and the formation of an industrial base. As my country is rich in metal resources such as lithium, cobalt, manganese, and nickel required for the production of lithium battery cathode materials, the downstream use of lithium batteries such as consumer electronics and new energy vehicles is rapidly expanding. In recent years, the career of lithium battery cathode materials in my country has continued to expand. The concentration of domestic lithium battery cathode materials occupations is relatively high, and three major lithium battery cathode materials industrial bases have been formed in the Beijing-Tianjin region, the middle and lower reaches of the Yangtze River and the South China region. (3) The development of lower-class occupations drives new growth in the industry. Driven by the rapid expansion of lithium batteries and its lower-class occupations, the positive data of lithium batteries are newly added rapidly. As a key component of electric vehicles, the power lithium battery is one of the key components that affect the performance, cost and user experience of the entire vehicle. It is also the component that accounts for the largest proportion of the entire vehicle cost, and its cost accounts for half of the entire vehicle cost. In terms of breakdown, the cost of the four key materials of positive electrode material, negative electrode material, separator and electrolyte accounted for more than half of the battery cost. Among them, the cost of cathode materials also accounts for about 40% of the total cost of lithium batteries. (4) Continuous innovation of skills Relying on the Yunnan Province Advanced Battery Data Key Laboratory built by Kunming University of Science and Technology, the main focus is on lithium batteries and key data, and core skills such as lithium ion ternary battery cathode data, battery preparation and management have been developed. Since the 13th Five-Year Plan, new breakthroughs have been made in the development of long-life high-nickel cathode materials with a core-shell structure, which has significantly improved the cycle stability of high-nickel cathode materials. With the support of national key research methods, the team of Professor Xia Dingguo of Peking University launched a new high specific energy manganese-based cathode material research, breaking the limitations of traditional modification methods such as doping, coating, and nano-tracing, and combined LiMO2 phase with single-layer Li2MnO3 Phase recombination prepared a manganese-based lithium-rich power lithium-ion battery cathode material with O2 configuration. This positive electrode material has a specific discharge capacity of more than 400mAh/g and a specific energy density of more than 1380Wh/kg, which provides the possibility for the development of new lithium batteries with a specific energy greater than 500Wh/kg. It has the highest specific energy reported at home and abroad. Manganese-based lithium-rich cathode materials for high-density lithium batteries. The study provided a new direction for the planning of new high specific energy lithium battery cathode materials, and broke the limitation of foreign layered manganese-based lithium-rich materials patents (O3 configuration). 2. Disadvantages (1) Oversupply of low-end products and lack of high-end products. Since the output of cathode materials in my country is mainly concentrated in low-end products, there is still a lack of output in some high-end products, such as high-performance ternary materials. Therefore, the lithium battery cathode material industry is currently in a stage of oversupply, and the main driving force in the future will come from the increased demand for power lithium-ion batteries. And in terms of product distribution, the output of low-end products is surplus, and the supply of high-end products is lacking. (2) There is a certain distance from the advanced companies in Japan and South Korea. The positive electrode material companies with a certain output and reputation in the world are mainly gathered in Japan, my country and South Korea. The scale of the positive electrode material companies in other countries in the world is relatively small, and the products are relatively single. Therefore, the above-mentioned three countries are recognized as the three giant countries in the global cathode materials industry. Japan and South Korea started their careers in cathode materials earlier. In recent years, they have been committed to high-end cathode materials such as ternary materials. However, domestically, due to various reasons, the lithium battery cathode materials industry was concentrated in phosphoric acid in the past. Lithium iron, following the development of the new energy vehicle industry in the past two years, the country and companies have gradually paid attention to the development of the ternary data industry, but there is still a certain gap between the skills and advanced companies in Japan and South Korea. (3) The replacement of risk lithium battery cathode materials occupational products are fast in updating and upgrading, and the performance requirements continue to increase. In addition, alternative technologies such as fuel power batteries, lithium-sulfur batteries, and lithium-air batteries, although it will take time for large-scale industrialization, do not rule out the risk of technological innovation replacing existing products in the future.
