Claim 0:
1. An electrolyte medium for a lithium secondary battery, the electrolyte medium comprising:
an electrolytic solution; and
a polyvalent cation salt,
the electrolytic solution comprising a low dielectric constant solvent having a dielectric constant of less than 10 and a lithium salt,
the polyvalent cation salt being in a state in which particles of the polyvalent cation salt are dispersed in the electrolytic solution and can flow without being immobilized,
the polyvalent cation salt having a content of 0.1 mass % to 50 mass %, and
the electrolytic solution not comprising a high dielectric constant solvent having a dielectric constant of greater than 50 or comprising the high dielectric constant solvent at a content of 20 mass % or less with respect to the total mass of the electrolyte medium.
