In order to overcome the problems of insufficient high-temperature storage performance and high-temperature cycle performance of existing lithium-ion batteries, the present invention provides a non-aqueous electrolyte for lithium-ion batteries, comprising a bicyclic sulfate compound and compound A shown in structural formula 1: In Structural Formula 1, R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 are each independently selected from hydrogen, fluorine atoms, or groups containing 1 to 5 carbon atoms. At the same time, the present invention also discloses a lithium ion battery comprising the above non-aqueous electrolyte for the lithium ion battery. The non-aqueous electrolyte for the lithium ion battery provided by the invention is beneficial to improve the high temperature storage and high temperature cycle performance of the battery. |
