    Abstract: The application relates to the technical field of lithium ion batteries, in particular to a non-aqueous electrolyte and a lithium ion battery. In order to overcome the technical problem of poor high-temperature performance of the existing lithium ion battery, the application provides a non-aqueous electrolyte, comprising a solvent, a lithium salt and at least one of bicyclic compound represented by structural formulas 1-1 to 1-3: Meanwhile, the application also discloses a lithium ion battery comprising the non-aqueous electrolyte. The non-aqueous electrolyte and the lithium ion battery provided by the application can effectively improve the high-temperature cycle performance and high-temperature storage performance of battery.
