What is the component of electrolyte of lithium battery？

Lithium battery electrolyte composition introduction:

1. Vinyl carbonate: molecular formula: C3H4O3

Transparent colorless liquid (>35 ° C), crystalline solid at room temperature. Boiling point: 248 ° C / 760 mmHg, 243-244 ° C / 740 mmHg; flash point: 160 ° C; density: 1.3218; refractive index: 1.4158 (50 ° C); :35-38 ° C; This product is a good solvent for polyacrylonitrile and polyvinyl chloride. It can be used as a spinning solution on textiles. It can also be used directly as a solvent for removing acid gases and as an additive for concrete; it is available in medicine. It is used as a component and raw material for pharmaceuticals; it can also be used as a stabilizer for plastic foaming agents and synthetic lubricating oils; it can be used as an excellent solvent for lithium battery electrolytes in the battery industry.

2. The propylene carbonate molecular formula: C4H6O3

Colorless, odorless, or light yellow transparent liquid, soluble in water and carbon tetrachloride, miscible with ether, acetone, benzene, etc. It is an excellent polar solvent. This product is mainly used for polymer operation, gas separation. Process and electrochemistry. Especially used to absorb carbon dioxide from natural gas and petrochemical plants. It can also be used as plasticizer, spinning solvent, olefin and aromatics extractant.

Toxicological data: no animal poisoning was found in oral or dermal exposure in rats. Oral LD50=2,9000mg/kg.

This product should be stored in a cool, ventilated, dry place, away from fire, according to general low-toxic chemicals regulations storage and transportation.

3. Diethyl carbonate molecular formula: CH3OCOOCH3

Colorless liquid, slightly odor; vapor pressure 1.33kPa / 23.8 ° C; flash point 25 ° C (flammable liquid can be volatilized into steam, run into the air. The temperature rises, the volatilization accelerates. When the volatilized vapor and air mixture and When the fire source is in contact with flashing sparks, the short-lived combustion process is called flashing, and the lowest temperature at which flashing occurs is called the flash point. The lower the flash point, the greater the risk of fire.); Melting point -43 °C ; boiling point 125.8 ° C; solubility: insoluble in water, miscible in alcohol, ketone, ester and other organic solvents; density: relative density (water = 1) 1.0; relative density (air = 1) 4.07; stability: stable Hazard symbol 7 (flammable liquid); main use: as a solvent and for organic synthesis.
