Abstract
The application provides a non-aqueous electrolyte for lithium ion battery. The non-aqueous electrolyte for lithium ion battery comprises a compound A represented by formula I and a compound B represented by formula II, In formula I, R, Rand Rare independently selected from C1-C5 alkyl or haloalkyl, C2-C5 unsaturated hydrocarbon group or unsaturated halohydrocarbon group, and at least one of R, Rand Ris the unsaturated hydrocarbon group or unsaturated halohydrocarbon group; In formula II, R, R, R, R, Rand Rare each independently selected from one of hydrogen atom, fluorine atom and C1-C5 group. The non-aqueous electrolyte for lithium ion battery provided by the application enables the battery to have excellent cycle performance and high-temperature storage performance through the synergistic effect of the compound A and the compound B.
