Abstract

PURPOSE:To increase the charge-discharge performance of a lithium electrode by using at least lithium 7,7,8,8-tetracyanoquinodimethanide as a lithium salt in an electrolyte. CONSTITUTION:An electrolyte containing at least lithium 7,7,8,8- tetracyanoquinodimethanide as a lithium salt is used. By using this electrolyte, a protection film is formed on the surface of deposited lithium to retard the reaction of the deposited lithium with a solvent which causes a deterioration in charge discharge efficiency of a lithium electrode. Since the lithium 7,7,8,8- tetracyanoquinodimethanide is used for forming the protection film on the surface of lithium, the addition of a small amount of this salt in the electrolyte having usual solute and solvent shows enough effect. The charge-discharge performance of a lithium electrode is therefore improved.
