What materials are in a lithium ion battery?

What is a lithium battery electrolyte?

The electrolyte of a lithium battery is the carrier of ion transport in a lithium battery. Usually a combination of lithium salt and a high boiling point solvent. The electrolyte has the effect of transporting ions between the positive and negative electrodes of the lithium battery, which is the guarantee of high voltage, high specific energy and other advantages of lithium-ion batteries. The electrolyte is usually made of very high purity high boiling point solvent, electrolyte lithium salt, necessary additives and other raw materials, under certain conditions, in proportion to the proportion, polymer lithium batteries are produced according to this ratio.
Solvents commonly used in lithium battery electrolytes
In the process of charging and discharging the battery, the PC decomposes on the graphite negative surface and triggers the peeling off of the graphite layer at the same time, causing the cyclic safety factor of the lithium battery to drop.
Main components of lithium battery electrolyte
1. Acrylic carbonate molecular structure: C4H6O3
Crystal clear without odor, or light yellow crystal clear liquid, soluble in water and carbon tetrachloride, miscible with ether, acetone, benzene, etc. It is an excellent polar solvent. This product is key for use in polymer work, vapor stripping processes and natural pharmaceutical chemistry.
2.Ethylene carbonate:Molecular structure:C3H4O3
Very high purity electrolyte for rechargeable lithium-ion battery; scraping liquid for textile industry; directly used as solvent for removing acid gas and additive for concrete; raw material for dysentery in biomedicine; chemical book for plastic foaming agent and stabilizer for fully synthetic motor oil; solvent with excellent safety factor and intermediate for chemical synthesis; good solvent for acrylonitrile and polyvinyl chloride; basic raw material for natural drug chemical industry; as hydroxyl ethyl chemical agent and chemical raw material for chemical synthesis; sodium silicate system pulp, fiber finishing agent
