Key components of lithium-ion battery electrolyte

Lithium Iron Phosphate Battery Electrolyte Main Components,LiFePO4 Battery Electrolyte Price.

Lithium Polymer Battery electrolyte consists of three major - organic solvent, lithium salt, additives under certain conditions, according to a certain proportion of the preparation.

Key components of Maintenance Free Battery Lithium Iron Phosphate Battery electrolyte

The electrolyte consists of three main parts:

1. Solvent: cyclic carbonate (PC, EC); chain carbonate (DEC, DMC, EMC); carboxylate esters (MF, MA, EA, MA, MP, etc.); (used to dissolve lithium salts).

2. Lithium salt: LiPF6, LiClO4, LibF4, LiAsF6, etc;

3. Additives: film forming additives, conductive additives, flame retardant additives, overcharge protection additives, additives to control H2O and HF content in the electrolyte, additives to improve low temperature performance, multifunctional additives.

Currently, the main electrolytes used in Lithium Batteries on the market are lithium perchlorate, lithium fluoride, lithium hexafluorophosphate, etc. Electrolyte is generally composed of high-purity organic solvent, electrolyte lithium salt, necessary additives and other raw materials, under certain conditions, according to a certain proportion of preparation. There are seven main ingredients:

1. Vinyl carbonate: Molecular formula: C3H4O3, bright colourless liquid (35℃), at room temperature as a crystalline solid, is a good solvent for polyacrylonitrile, polyvinyl chloride.

2. Propylene carbonate, colourless odourless or light yellow bright liquid, soluble in water and carbon tetrachloride, miscible with ether, acetone, benzene, etc. This product should be stored in a cool, ventilated, dry place, away from the source of fire, according to general low toxicity chemical storage and transportation.

3. Diethyl carbonate, colourless liquid, odour; Vapour pressure 1.33kPa/23.8℃; Flash point 25℃ Flammable liquid may evaporate into vapour, run into the air.

4. Dimethyl carbonate, a non-toxic, environmentally friendly and widely used chemical raw material; At the same time, it has higher evaporation temperature and faster evaporation speed.

5. Methyl Ethyl Carbonate, colourless transparent liquid, is the rise of high-tech, high value-added chemical products in recent years, an excellent solvent of LiFePO4 Battery electrolyte, this product should be stored in a cool, ventilated, dry place, according to the provisions of flammable chemicals storage and transportation.

6. Lithium hexafluorophosphate, white crystal or powder, strong deliviousness; analysis on exposure to air or heat, lithium hexafluorophosphate in air by the use of water vapour rapid analysis, release PF5 and white smoke initiation.

7. Phosphorus pentafluoride is a phosphorus halide compound. Phosphorus pentafluoride is a colourless odourless gas at normal temperature and pressure, which is highly irritating to skin, eyes and mucous membranes. Phosphorus pentafluoride is used as a catalyst for polymerisation.
