Abstract: An electrolyte, including a fluorine-containing phosphate ester and a carboxylate ester, wherein the fluorine-containing phosphate ester is represented by Formula 1: R1, R2 and R3 are each independently selected from hydrogen, a C1-C10 alkyl group, C1-C10 alkoxy group, C1-C10 haloalkyl group, C1-C10 haloalkoxy group, C1-C10 phosphate ester group, or C1-C10 mono- or multiple-carbonate ester group, wherein at least one of R1, R2 and R3 comprises a fluorine atom. The weight ratio of the fluorine-containing phosphate ester to the carboxylate ester is 0.001-0.5.

Abstract: An electrolyte, comprising a compound of Formula I and an additive A,




R1, R2, R3, R4, R5, R6, R7 and R8 are each independently selected from: hydrogen, halo, —COOX, substituted or unsubstituted C1-8alkyl, substituted or unsubstituted C2-10alkenyl, substituted or unsubstituted C2-10alkynyl, substituted or unsubstituted C1-8alkoxy, or —Ra—S(═O)2—Rb, wherein Ra is selected from substituted or unsubstituted C1-8alkylene, Rb is selected from halo or substituted or unsubstituted C1-8alkyl, and at least one of R1, R2, R3, R4, R5, R6, R7 and R8 is —COOX. When substituted, the substituent is selected from cyano or halo; and



X is selected from Li+, Na+, K+ or Rb+. The additive A is at least one selected from fluoroethylene carbonate, LiPO2F2, or vinylene carbonate.

Abstract: An electrolyte, including a compound of formula I and lithium difluorophosphate, where X is selected from a substituted or unsubstituted C1-10 alkyl group, a substituted or unsubstituted C2-10 alkenyl group, a substituted or unsubstituted C1-5 alkyl sulfonyl group, and a substituted or unsubstituted C2-5 acyl group. In the case of substitution, a substituent is selected from a cyano group and halogen. This application further relates to an electrochemical apparatus and an electronic apparatus that include the electrolyte.
