Abstract: Embodiments of the present application provide an electrolyte and a lithium ion battery including the same. The electrolyte comprises a trinitrile compound of general formula (I), wherein R11, R12, and R13 are each independently selected from alkylene groups having 0 to 8 carbon atoms, and R11, R12, and R13 are not 0 simultaneously; and fluorosulfonyl silane acetate. The present application improves the cycle performance, rate performance and floating charge performance of lithium ion batteries by using the trinitrile compound and fluorosulfonyl silane acetate in combination.
