| titleOfInvention | Lithium ion battery electrolyte and lithium ion battery |
| abstract | The invention belongs to the fields of lithium ion batteries, and provides a lithium ion battery electrolyte. The lithium ion battery electrolyte comprises electrolyte salt, a mixed solvent and an additive, wherein the mixed solvent comprises an ethylene carbonate/diethyl carbonate/ethyl methyl carbonate ternary organic solvent system, liner carboxylate with the carbon atom number of no more than 5, and vinylene carbonate which accounts for 1.5 to 2 weight percent of the total mass of the electrolyte; the additive is 1,3-propenyl sultone; and the ratio of the mass percentage of the liner carboxylate with the carbon atom number of no more than 5 based on the electrolyte to that of the 1,3-propenyl sultone based on the electrolyte is 40-350. The electrolyte solves the technical problems of difficulties of simultaneously improving the high-temperature and low-temperature properties of the battery from an electrolyte formula, and better improves the high-temperature and low-temperature properties of the lithium ion battery simultaneously. |
