Abstract: To provide a lithium secondary battery capable of suppressing short circuits and having high energy density and high output. An electrolyte medium for a lithium secondary battery includes a low dielectric constant solvent, a lithium salt, and a polyvalent cation salt. The polyvalent cation salt is dispersed as particles in the electrolyte medium and can flow without being immobilized. The electrolyte medium includes 20 mass % or less of a high dielectric constant solvent. A lithium secondary battery including the electrolyte medium for a lithium secondary battery can suppress short circuits and provide high energy density and high output.
