| titleOfInvention | Electrolyte and lithium ion battery containing same |
| abstract | The invention provides aThe electrolyte comprises a lithium salt, an electrolyte solvent and an additive, wherein the additive is fluoroethylene carbonate and/or 1, 2-difluoroethylene carbonate, and the electrolyte is characterized by also comprising an inhibitor, wherein the inhibitor is an epoxy compound and a derivative thereof, and has a structure shown in a formula (1), wherein R can be one selected from-H, - (CH2) n1CH3 and- (CH2) n2X, and X is one selected from-F, -Cl, -Br and-I; n1 is more than or equal to 0 and less than or equal to 5; n2 is more than or equal to 1 and less than or equal to 2. The invention also provides a lithium ion battery containing the electrolyte. In the electrolyte provided by the invention, the epoxy compound and the derivative thereof with the structure are used as the specific inhibitor, so that the technical problems that the electrolyte additive fluoroethylene carbonate and/or 1, 2-difluoroethylene carbonate can generate decomposition reaction under alkaline conditions to generate HF, the HF can damage the surface structure of an electrode dressing, the battery cycle performance is reduced, and the battery expansion is increased at high temperature can be solved. |
