The application provides an electrolyte and a lithium ion battery, belonging to the technical field of batteries. The electrolyte includes an organic solvent, a lithium salt dissolved in the organic solvent, and an auxiliary agent. The auxiliary agent is selected from one or more of S element, B element, P element and reducing compounds that can release specific negative ions in the electrolyte, and the specific negative ion is selected from one or more of S negative ions, B negative ions and P negative ions. kind. Lithium-ion batteries include this electrolyte. Specific types of additives can effectively reduce the potential of the lithium-containing compound during decomposition; the way of adding the additives to the electrolyte ensures that the battery has good cycle stability and has good applicability in the battery production process. |
