Explanation of important components of lithium battery electrolyte

Analysis of important components of lithium battery electrolyte: 1. Molecular formula: C3H4O3 transparent colorless liquid (>35℃), crystalline solid at room temperature. Boiling point: 248℃/760mmHg, 243-244℃/740mmHg; flash point: 160℃; density: 1.3218; refractive index: 1.4158 (50℃); melting point: 35-38℃; this product is polyacrylonitrile and polyvinyl chloride The excellent solvent. It can be used for spinning; it can also be used directly as a solvent to remove acid gases and concrete additives. As medicinal ingredients and materials; it can also be used as plastic foaming agent and synthetic oil stabilizer; in the battery industry, it can be used as an excellent solvent for lithium battery electrolyte 2. Molecular formula: C4H6O3 is colorless and odorless, or light yellow transparent liquid, Soluble in water and carbon tetrachloride, and miscible with ether, acetone, benzene, etc. It is an excellent polar solvent. This product is mainly used in polymer operations, gas separation technology and electrochemistry. In particular, it can be used to absorb carbon dioxide from natural gas and synthetic ammonia in petrochemical plants. It can be used as plasticizer, spinning solvent, olefin, aromatic extraction agent, etc. Toxicological data: No toxicity was found in animal experiments by oral or skin contact. LD50u003d2,9000mg/kg. This product should be stored in a cool, ventilated, dry place, away from fire, and stored and transported in accordance with the regulations for low-toxic chemicals. 3. Diethyl carbonate: CH3OCOOCH3 colorless liquid with slight odor; vapor pressure: 1.33kpa/23.8°C; flash point 25°C (flammable liquid will evaporate into vapor and flow into the air. Temperature rises, evaporation accelerates. When When the mixture of vaporized steam and air sparks when it comes into contact with a fire source, this brief combustion process is called flashover, and the lowest temperature at which flashover occurs is called the ignition 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, soluble in organic solvents such as alcohols, ketones, esters, etc.; density: relative density (water u003d 1) 1.0; relative density (air u003d 1) stability: stability ; Danger sign 7 (flammable liquid); important uses: solvents and organic synthesis. Lithium salts used in lithium batteries are generally LiPF6, LiBF4, LiClO4, LiAsF6, LiCF3SO3, LiN(CF3SO2)2 and other substances, most of which are easy to hydrolyze and heat Poor stability.
