Kind Code:
A1
Abstract:
The present application relates to an electrolyte solution. The electrolyte solution comprises an organic solvent and an electrolyte salt dissolved in the organic solvent, wherein the electrolyte salt comprises an alkali metal double salt, and the alkali metal double salt contains a lithium ion and at least one other alkali metal ion other than the lithium ion. The present application also relates to a corresponding secondary battery, battery module, battery pack and electric device. According to the electrolyte solution, an alkali metal double salt containing a lithium ion and at least one other alkali metal ion other than the lithium ion is used in an electrolyte salt, such that the cycle performance of a secondary battery can be effectively improved, and the cycle life of the secondary battery is prolonged; and extra impurities cannot be introduced, such that side reactions cannot be caused.
