| titleOfInvention | Non-water system high-voltage electrolyte additive and preparation method of electrolyte |
| abstract | The invention discloses a preparation method of high-voltage electrolyte, comprising the following steps of: (1). mixing a ring-shaped carbonate solvent with a chain-shaped carbonate solvent, wherein the mass ratio of the ring-shaped carbonate solvent to the chain-shaped carbonate solvent is 1: (1-3); (2). adding a conductive lithium salt into the mixed solvent to enable the concentration of the lithium salt to be 0.6-1.5 mol/L; and (3). adding a lithium ion battery electrolyte additive in the claim 1 into a mixed system of the step (2) to enable the mass of the additive to be 0.01-5% of the total mass of the electrolyte. According to the electrolyte prepared by the preparation method disclosed by the invention, no special requirements on a cathode material and a membrane exist so that the circulating performance of a high-voltage lithium ion battery is obviously improved and the multiplying power performance is further improved. The electrolyte prepared by the preparation method disclosed by the invention has smaller influences on the battery capacity; and the preparation method disclosed by the invention is simple, is low in cost, and has good application prospect. |
