Abstract
An electrolyte solution of a lithium ion battery is provided by limiting a relative ratio of cyclic ester to lithium salt in the electrolyte solution of the lithium ion battery, the electrolyte solution simultaneously containing the cyclic ester and the lithium salt has good conductivity, oxidation resistance, system stability and proper viscosity, and conductivity of a negative interface film may be improved, such that the lithium ion battery containing the electrolyte solution has a remarkably improved high-temperature storage performance and high-temperature cycle performance, and meanwhile has a good power performance.
