Abstract
Provide is a non-aqueous electrolyte for lithium ion battery, comprising a compound represented by structural formula I: In formula I, R, R, Rand Rare each independently selected from hydrogen atom, fluorine atom, cyano group, hydrocarbyl group or halogenated hydrocarbyl group having 1-5 carbon atoms, oxygen-containing hydrocarbyl group having 1-5 carbon atoms, silicon-containing hydrocarbyl group having 1-5 carbon atoms, X is a —O—R—CN group, Ris a hydrocarbyl group or a halogenated hydrocarbyl group having 1-5 carbon atoms, m, n, z and y are integers of 0 or 1, and m+n+y+z≠0. When the non-aqueous electrolyte is used for lithium ion battery, the decomposition of electrolyte on the surface of electrode can be inhibited, and the high-temperature storage performance is improved with less gas generation and small expansion rate, therefore the high-temperature cycle performance and high-temperature storage performance of the battery are effectively improved.
