Inventor: LIANG CHENGDU
IPC: H01M10/0567
Filed: 2020-04-07
Abstract: The present application provides an electrolyte solution, lithium-ion battery, and device containing said lithium-ion battery. The electrolyte solution comprises lithium salt, organic solvent, and additives. The additives comprise a sulfur-containing compound and lithium difluorophosphate, and the reduction potential of the sulfur-containing compound is higher than the reduction potential of lithium difluorophosphate. The reduction potential of the sulfur-containing compound is higher than that of lithium difluorophosphate, therefore said compound can form a low-impedance SEI film on the surface of the negative electrode before the lithium difluorophosphate to reserve more lithium difluorophosphate to form a passivation film having good thermal stability on the surface of the positive electrode, so that the lithium-ion battery has better high-temperature storage performance and cycle performance, while no situations of degradation of performance such as lithium precipitation occur; at the same time, the force between the molecules of the sulfur-containing compound is small, which can effectively reduce the viscosity of the electrolyte solution after dissolving in the electrolyte solution, thereby further improving the dynamic performance of the lithium-ion battery.
