　　What raw materials are mainly used in the production of lithium batteries

　　Lithium battery material composition is mainly: positive electrode materials, negative materials, diaphragm, electrolyte.

　　1. Among the positive materials, the most commonly used materials are lithium cobaltate, lithium manganate, lithium iron phosphate, and ternary lithium battery material (polymer for nickel cobalt manganese). Positive material materials occupy a large proportion (the quality ratio of positive and negative poles is 3: 1 ~ 4: 1), because the performance of the positive pole material directly affects the performance of lithium -ion batteries, and its cost also directly determines the cost of battery costs.

　　2. Among the negative materials, the current negative materials are mainly natural graphite and artificial graphite. The negative materials are being explored include nitride, PAS, tinl oxide, tin alloy, nano -negative electrode materials, and other inter -metal inter -compounds. As one of the four major consisting of lithium battery materials, lithium battery manufacturers have played an important role in improving the capacity of the battery and circulating performance. They are in the core link of the lithium battery industry.

　　3. Market -oriented diaphragm materials are mainly polyolefin -based partitions with polyethylene (PE) and polypropylene (PP). In the structure of the lithium battery, 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 characteristics of the battery capacity, cycle, and safety performance. Optomic septum with excellent performance has an important role in improving the comprehensive performance of the battery.

　　4. Electrolytic solution is generally made of high -purity organic solvents, electrolyte lithium salt, and necessary additives. Under a certain condition, it is prepared according to a certain proportion. The electrolyte plays the role of transmission between the positive and negative electrodes of the lithium battery, and it is a guarantee for the advantages of lithium ion batteries to obtain high voltage and high ratio energy.
