The present application relates to the field of energy storage materials, and in particular, to an electrolyte and a battery. An electrolyte solution, including an organic solvent, an electrolyte and an additive, the additive includes an additive A and an additive B, the additive A is selected from at least one of the compounds represented by the general formula I, the general formula II, and the general formula III, and the additive B is selected from At least one of a fluorophosphate compound and a fluorophosphite compound. The electrolyte of the present application can significantly improve the high temperature cycle performance and high temperature storage performance of the battery under high pressure conditions. |
