What are the raw materials produced by lithium battery packs

There are many raw materials in the production of lithium battery packs, and the key materials of lithium battery packs include: positive electrode material, negative electrode material, separator, and electrolyte. Lithium batteries are a new generation of green high-energy batteries with excellent performance and have become one of the focuses of high-tech development. At present, the supply of raw materials for lithium battery packs is sufficient, the output of some products is sufficient, and the competition is fierce. The lithium battery industry is still hot. The raw materials for the production of lithium battery packs generally have an oversupply situation in the low-end and middle-end products and the supply of high-end products is in short supply. Among them, cathode materials, anode materials, and electrolytes have gradually become self-sufficient. Due to the relatively low technical barriers of anode materials and electrolytes, the cost advantages of Chinese companies clearly have strong competitiveness on a global scale. 1. Cathode materials Among the cathode materials, the most commonly used materials are lithium cobaltate, lithium manganate, lithium iron phosphate and ternary materials (a polymer of nickel, cobalt and manganese). The positive electrode material occupies a large proportion (the mass ratio of positive and negative materials is 3:1~4:1), because the performance of the positive electrode material directly affects the performance of the lithium battery, and its cost directly determines the cost of the battery. Lithium battery cathode materials have a broad market and the prospects are very optimistic. However, lithium battery cathode materials still have certain technical bottlenecks, especially its advantages of high capacity and strong safety performance have not been fully utilized. Chinese companies should strengthen the research and development of key technologies for cathode materials, gain an international leading position, strengthen their core competitiveness, and gain advantages in international competition. 2. Anode materials Among the anode materials, the current anode materials are mainly natural graphite and artificial graphite. The anode materials being explored include nitrides, PAS, tin-based oxides, tin alloys, nano-anode materials, and other intermetallic compounds. As one of the four major constituent materials of lithium battery packs, anode materials play an important role in improving battery capacity and cycle performance, and are at the core of the midstream of the lithium battery industry. 3. Diaphragm market-oriented diaphragm materials are mainly polyolefin diaphragms mainly made of polyethylene and polypropylene. In the structure of the lithium battery, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The excellent diaphragm has an important purpose for improving the overall performance of the lithium battery pack. 4. Electrolyte Lithium battery electrolyte is the carrier of ion transmission in the battery. It is generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials under certain conditions and proportions. The electrolyte serves the purpose of conducting ions between the positive and negative electrodes of the lithium battery pack, which guarantees that the lithium battery obtains the advantages of high voltage and high specific energy.
