18650 battery rechargeable

　　The composition of 18650 battery rechargeable electrolyte:

　　1. Ethylene carbonate: Molecular formula: C3H4O3

　　Colorless liquid (>35℃), can be used at room temperature, boiling point: 248c/760mmhg, 243-244c/740mmhg, opening flash point: 160c, relative density: refractive index: (50c), solution: 35-38c, it is polypropylene A good organic solvent for nitrile and polyvinyl chloride, it can be used as a spinning fluid on textiles, a solvent for removing acid gases, and an additive for concrete; it can be used as a preservative for resins that absorb acidic gases and as a raw material for the pharmaceutical industry, and it can also be used as a plastic Stabilizer for foam and synthetic lubricants, and can be used as a high-quality solvent in the lithium battery electrolyte industry.

　　2. Molecular formula of propylene carbonate: C4H6O3

　　This product is a high-quality polar solvent, mainly used in polymer materials, gas separation processes and photoelectrocatalysis. It is very useful for absorbing gases and digesting carbon dioxide in raw materials for ammonia synthesis processes in petrochemical plants. It can also be used as a viscosity increaser. agent, spinning organic solvent, cyclohexanol and p-xylene extraction agent.

　　Toxicology data: No internal or skin toxicity was found, rat oral LD50=2,9000mg/kg.

　　This product should be stored in a cool, well-ventilated, dry, non-flammable place to prevent fire, in accordance with the general requirements for slightly toxic chemicals.

　　3. Chemical formula of diethyl carbonate: ch3ocooh3

　　No color, slightly odor; saturated vapor pressure; flash point 25 degrees (flammable liquid evaporates into steam, heats up to air, and accelerates evaporation. When steam and gas compounds can flash through the flame, the entire process of this transient ignition is called For flash ignition, the lowest temperature at which flash ignition occurs is called the flash point. The lower the flash point, the greater the risk of fire accidents. Melting point -43℃; Boiling point ℃; Solubility: Insoluble in water, miscible in alcohol and ketone. , esters and other organic solvents; density: relative density (water = 1) relative density (air = 1) stability: stable; hazard mark 7 (flammable liquid); important uses: used as solvents and in organic synthesis
