The important components of lithium battery materials include: positive electrode material, negative electrode material, separator, and electrolyte. In recent years, policies related to lithium batteries have been introduced successively to promote the establishment of upstream and downstream companies in the industry like mushrooms. Cathode materials account for more than 40% of the total cost of lithium batteries, and the performance of cathode materials directly affects various performance indicators of lithium batteries, so lithium battery cathode materials occupies a core position in lithium batteries. 1. 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). Cathode materials occupies a large proportion, because the performance of cathode materials directly affects the performance of lithium batteries, and its cost directly determines the cost of the battery. 2. 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 batteries, anode materials play an important role in improving battery capacity and cycle performance, and are at the core of the middle reaches of the lithium battery industry. 3. Market-oriented diaphragm materials are mainly polyolefin diaphragms based on polyethylene and polypropylene. In the structure of lithium batteries, the diaphragm is one of the key inner 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. A diaphragm with excellent performance has an important purpose for improving the overall performance of the battery. 4. The electrolyte is generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials under certain conditions and in a certain proportion. The electrolyte is used to conduct ions between the positive and negative electrodes of the lithium battery, which guarantees that the lithium battery obtains the advantages of high voltage and high specific energy.
