Abstract: An electrolyte includes a compound of formula 1: formula 1. R1 and R2 are each independently selected from H, halogen atom, a substituted or unsubstituted C1-10 alkyl group, a substituted or unsubstituted C3-10 cycloalkyl group, a substituted or unsubstituted C2-10 alkenyl group, a substituted or unsubstituted C2-10 alkynyl group, a substituted or unsubstituted C1-10 alkoxy group, a substituted or unsubstituted C6-10 aryl group, a substituted or unsubstituted C3-10 heteroaryl group, or any combination thereof. R is selected from a substituted or unsubstituted C1-10 alkyl group, a substituted or unsubstituted C3-10 cycloalkyl group, a substituted or unsubstituted C2-10 alkenyl group, a substituted or unsubstituted C2-10 alkynyl group, a substituted or unsubstituted C1-10 alkoxy group, a substituted or unsubstituted C6-10 aryl group or a substituted or unsubstituted C3-10 heteroaryl group, a substituted or unsubstituted C3-10 heterocycloalkyl group, a butyrolactam group, or any combination thereof.

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.
