Abstract

See full text

In the embodiments of the present application, an electrolyte, a lithium-ion battery comprising the electrolyte, a battery module, a battery pack, and a device are provided. The electrolyte in the embodiments of the present application comprises an organic solvent, an electrolyte lithium salt dissolved in the organic solvent, and an additive comprising a first additive and a second additive. The first additive is selected from one or more of the compounds represented by formula I, and the second additive is selected from one or more of the compounds represented by formula II. After applying the electrolyte of the present application to a lithium-ion battery, the lithium ion battery has a better cycle performance and storage performance at a high temperature, and lower direct-current impedance at a low temperature, such that the lithium ion battery has both a better high-temperature performance and a better low-temperature performance.
