An electrolyte is a compound that can conduct electricity when dissolved in an aqueous solution or in a molten state, and can dissociate into freely moving ions when dissolved in water or heated. The electrolyte is an important part of the lithium-ion battery , which plays the role of transporting ions and conducting current between the positive and negative electrodes. Electrolyte, as a key material of lithium-ion batteries, affects or even determines the specific energy, life, safety performance, and charge-discharge performance of the battery. As a practical electrolyte for lithium-ion batteries, the following conditions should be met: 1. Lithium ion conductivity: The electrolyte does not have electronic conductivity, but it must have good ion conductivity. In the general temperature range, the conductivity of the electrolyte is between 1×10-3~2×10-3S/cm. As an electrolyte, it must have excellent ionic conductivity and electronic insulation, allowing it to function as ...

Lithium battery electrolyte is generally composed of lithium salt and organic solvent. The electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, which is the guarantee for the lithium ion battery to obtain the advantages of high voltage and high specific energy. The electrolyte is generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials under certain conditions and in a certain proportion. The important components of lithium-ion battery electrolyte are as follows: 1. Ethylene carbonate: Molecular formula: C3H4O3, transparent and colorless liquid (>35℃), crystalline solid at room temperature, a good solvent for polyacrylonitrile and polyvinyl chloride. 2. Propylene carbonate, colorless and odorless, or light yellow transparent liquid, soluble in water and carbon tetrachloride, miscible with ether, acetone, benzene, etc. This product should ...
