Abstract
In order to solve the problem of insufficient cycle performance and high-temperature storage performance of the existing non-aqueous electrolyte for lithium ion battery containing maleic anhydride copolymer, 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, Rand Rare independently selected from one of hydrogen atom, halogen atom, —O—Ror aryl, wherein n is a positive integer and Ris a C1-C4 alkyl 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 invention can improve the cycle stability and high-temperature storage performance of the battery through the effections of compound A and compound B.
