Document Type and Number:
WIPO Patent Application WO/2023/077330
Kind Code:
A1
Abstract:
Provided in the present application are an electrolyte, a secondary battery, and an electric device comprising the secondary battery. The electrolyte of the present application comprises a solvent. The solvent comprises a compound of formula (1) (in the formula, R1 is a fluorine-substituted C1-C6 alkyl group, or a fluorine-substituted C2-C6 alkenyl group; and R2 and R3 are the same or different, and are each independently a hydrogen atom, a fluorine atom or a fluorine-substituted C1-C6 alkyl group), and ethylene carbonate, wherein the content of the ethylene carbonate is less than or equal to 25 weight% relative to the total weight of the solvent. After the electrolyte of the present application is applied to a secondary battery, the secondary battery has high safety performance and a long cycle life.
