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 &#x2014;O&#x2014;R&#x2014;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&#x2260;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.

Non-aqueous electrolyte for lithium ion battery and lithium ion battery

A lithium-ion battery non-aqueous electrolyte solution, and a lithium-ion battery using the electrolyte solution. The electrolyte solution comprises one, two, or more of a compound as represented by structural formula I. R, R, R, R, R, and Rare independently selected from hydrogen, halogen atom, or a group comprising 1-5 carbon atoms. Presence of the compound as represented by structural formula I provides excellent performance at a high temperature and at a low temperature to the non-aqueous lithium-ion battery electrolyte solution.
