NON-AQUEOUS ELECTROLYTE FOR A HIGH-VOLTAGE LITHIUM BATTERY |
摘要 |
The invention relates to a positive electrode/electrolyte pair for lithium batteries operating at a voltage above 4.2 V versus Li+/Li. The electrolyte of the lithium battery used in the invention includes at least a first additive chosen from optionally substituted, cyclic or acyclic, carboxylic or dicarboxylic anhydrides and carboxylic or dicarboxylic acids, and mixtures thereof, and optionally a second additive which is a lithium salt, the total content of additive(s) being greater than or equal to 0.01% by weight and less than or equal to 30% by weight, relative to the total weight of electrolyte, and the positive electrode is made of a material having a spinel structure. The lithium batteries of the invention are applicable in particular in the field of portable equipment, such as telephones, computers, camcorders, cameras and tooling. |
