Solid-liquid battery

Abstract

A solid-liquid battery includes a solid electrolyte provided between a positive electrode and a negative electrode made of metal lithium, an ester electrolyte solution is filled between the solid electrolyte and the positive electrode to increase the selection space of the positive electrode, and an ether electrolyte solution is filled between the solid electrolyte and the negative electrode to improve the cycle life of the lithium metal. By filling the electrolyte solution, the amount of the solid electrolyte used can be reduced, and the interface impedance of the battery can be reduced on the basis of ensuring that the safety is improved by using the solid electrolyte; furthermore, the existence of a solid electrolyte can prevent the influence of metal ions dissolved from the electrolyte on the performance of the negative electrode after migrating to the surface of lithium metal.
