The main components of lithium battery electrolyte, the harm of electrolyte components.

Lithium battery electrolyte is the carrier of ion transmission in the battery. It conducts ions between the positive and negative electrodes of the lithium battery. It is like the "love tie" between the positive electrode and the negative electrode. Guarantee of high specific energy and other advantages. So what are the main components of lithium battery electrolyte? What is the harm of electrolyte composition?

Main components of lithium battery electrolyte

1.Ethylene Carbonate: Molecular formula: C3H4O3, transparent and colorless liquid (>35°C), crystalline solid at room temperature, and a good solvent for polyacrylonitrile and polyvinyl chloride.

2.Propylene carbonate, colorless, odorless, or light yellow transparent liquid, soluble in water and carbon tetrachloride, and miscible with ether, acetone, benzene, etc. This product should be stored in a cool, ventilated, dry place, away from fire, and stored and transported in accordance with the regulations of general low-toxic chemicals.

3.Diethyl carbonate, colorless liquid, slightly odor; vapor pressure 1.33kPa/23.8°C; flash point 25°C (flammable liquid can volatilize into vapor and run into the air.

4.Dimethyl carbonate is a non-toxic, environmentally friendly, and versatile chemical raw material; at the same time, it has a higher evaporation temperature and a faster evaporation rate.

5.Ethyl methyl carbonate, a colorless and transparent liquid, is a high-tech, high value-added chemical product that has emerged in recent years. It is an excellent solvent for lithium battery electrolyte. This product should be stored in a cool, ventilated and dry place. The storage and transportation of inflammable chemicals are stipulated.

6.Lithium hexafluorophosphate, a white crystal or powder, is highly deliquescent; it decomposes when exposed to the air or heated, and when exposed to the air or heated, lithium hexafluorophosphate decomposes rapidly in the air due to the action of water vapor, releasing PF5 and producing white smoke.

7.Phosphorus pentafluoride is a phosphorus halide compound. Phosphorus pentafluoride is a colorless malodorous gas at normal temperature and pressure, and it is strongly irritating to the skin, eyes, and mucous membranes. Phosphorus pentafluoride is used as a catalyst for the polymerization reaction.
