Abstract:
The embodiments of the present application provide an electrolyte solution and a lithium-ion battery comprising the same. The electrolyte solution includes a solvent, a lithium salt and a first additive, and the first additive has a molecular formula of
wherein R is at least one of an H element, a halogen element or an alkyl group having 1 to 3 carbon atoms. The electrolyte solution provided in the embodiments of the present application has the advantages of having a long shelf life, avoiding the problem of the performance decline of lithium-ion batteries due to deterioration of electrolyte solutions, being capable of inhibiting an increase of internal resistance of the lithium-ion batteries in low-temperature cycles, and improving the performance of the lithium-ion batteries.
