What is the composition of lithium battery electrolyte

Lithium battery electrolyte composition 1. Ethylene carbonate chemical formula: C3H4O3 transparent colorless liquid (>35 ℃); crystalline solid at room temperature. Boiling point: 248°C/760mmHg, 243-244°C/740mmHg; Flash point: 160°C; Density: 1.3218; Refractive index: 1.4158 (50°C); Melting point: 35-38°C; This product is polyacrylonitrile, polyvinyl chloride A good solvent. It can be used as a spinning liquid in textiles; it can also be used as a solvent for removing acid gases and an additive in concrete immediately; it can be used as a pharmaceutical component and raw material in medicine; it can also be used to stabilize plastic foaming agents and synthetic lubricants In the battery industry, it can be used as an excellent solvent for lithium battery electrolyte. 2. The chemical formula of propylene carbonate: C4H6O3 is colorless, odorless, or light yellow transparent liquid, dissolved in water and ccl4, and miscible with ether, acetone, benzene, etc. It is an excellent polar solvent. This product is mainly used in polymer operations, gas separation processes and electrochemistry. In particular, it is used to absorb carbon dioxide from natural gas and synthetic ammonia raw materials in petrochemical plants, and can also be used as plasticizers, spinning solvents, olefins and aromatics extractants, etc. Toxicological data: No poisoning was found in animal experiments by oral or skin contact. Rat oral LD50u003d2,9000mg/kg. This product should be stored in ventilated, ventilated, and dry air, away from open flames, and stored and transported in accordance with the regulations of general low-toxic chemicals. 3. Chemical formula of diethyl carbonate: C5H10O3 colorless liquid with a slight odor; vapor pressure 1.33kPa/23.8°C; flash point 25°C (flammable liquid can evaporate into vapor and run into the air. When the working temperature rises, evaporation accelerates. When the mixture of vaporized vapor and air comes into contact with an open flame and can flash through a spark, this short combustion link is called flash, and the lowest temperature at which flash occurs is called the flash point. The lower the flash point, the fire will be caused. The greater the danger.); Melting point -43℃; Boiling point 125.8℃; Solubility: insoluble in water, miscible in most organic solvents such as alcohols, ketones, esters, etc.; Density: relative density (water u003d 1) 1.0; Relative density (airu003d1) 4.07; stability: stable; hazard mark: flammable liquid; scope of application: used for solvents and for organic synthesis.
