(57) [Summary] [Structure] A gel-like product comprising a positive electrode, a negative electrode using lithium as an active material, and a polymer gel-like electrolyte obtained by impregnating a polymer with an electrolytic solution containing an electrolyte salt and an aprotic solvent. An electrolyte battery, wherein the aprotic solvent is a mixed solvent comprising an amine compound, an amide compound, a nitrile compound, a nitro compound or a nitrogen-containing heterocyclic compound (75 to 5% by volume) and a cyclic carbonic acid ester (25 to 95% by volume). Is. [Effect] The high-rate discharge capacity is large because the polymer gel electrolyte used is difficult to decompose. |
