Abstract
An electrolyte solution includes an electrolyte salt and an organic solvent, wherein the electrolyte salt includes lithium bis(fluorosulfonyl)imide (LiFSI), and the percentage mass content of the lithium bis(fluorosulfonyl)imide (LiFSI) in the electrolyte solution is 4.5%-11%; the organic solvent includes ethylene carbonate, and the percentage mass contents of the ethylene carbonate and the lithium bis(fluorosulfonyl)imide satisfy: 0.9≤W/(16.77%−W)≤2.9. The electrolyte solution of the present disclosure can make the battery take lower cell internal resistance, excellent high temperature storage performance and high temperature cycling performance into account at the same time.
