Lithium Battery Electrolyte Solvent
Nov 08, 2018

The electrolyte of lithium battery is the carrier of ion transport in battery. Generally consists of lithium salt and organic solvents. The electrolyte plays a role in conducting ions between the positive and negative electrodes of lithium-ion batteries, which ensures the lithium-ion batteries to obtain high voltage, high specific energy and other advantages. Electrolyte is usually made up of high purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials, under certain conditions, in a certain proportion.

 

1. vinyl carbonate: molecular formula: C3H4O3

Transparent colourless liquid (>35 C), crystalline solid at room temperature. Boiling point: 248 C/760 mmHg, 243-244 C/740 mmHg; flash point: 160 C; density: 1.3218; refractive index: 1.4158 (50 C); melting point: 35-38 C; this product is a good solvent for Polyacrylonitrile and polyvinyl chloride. It can also be used as a solvent for removing acidic gases and an additive for concrete, as a pharmaceutical ingredient and raw material, as a plastics foaming agent and a stabilizer for synthetic lubricants, and as a good solvent for lithium battery electrolyte in the battery industry.

 

2. propylene carbonate molecular formula: C4H6O3

Colorless, odorless, or yellowish transparent liquid, soluble in water and carbon tetrachloride, mixed with ether, acetone, benzene, etc. It is an excellent polar solvent. This product is mainly used for polymer operation, gas separation process and electrochemistry. Especially used to absorb carbon dioxide from the raw materials of natural gas and synthetic ammonia in petrochemical plants. It can also be used as plasticizer, spinning solvent, olefin and aromatic extractant.
