PURPOSE:To obtain a highly safe nonaqueous electrolytic secondary battery by dissolving Li salt into a melted salt in which Al halide is mixed with one or more selected from BPX, MEIX, and DMPrIX, thereby using the inflammable and nontoxic melted salt as an electrolyte. CONSTITUTION:A negative electrode having a light metal or its alloy as an active material and a positive electrode containing an active material which is electrochemically reversibly reacted with any one selected from Li ion, Al complexes and halide ions are provided. An electrolyte in which Li salt is dissolved in a melted salt in which Al halide is mixed with one or more selected from 1-butylpyridinium halide, 1-methyl-3-ethylimidazolium halide, and 1,2- dimethyl-3-propylimidazolium halide is provided. As the melted salt is inflammable and nontoxic, a highly safe nonaqueous electrolytic secondary battery can be formed. |
