PURPOSE:To obtain capability which satisfies simultaneously high energy density, low self-discharge, high charge-discharge efficiency and a long cycling life by using a polyaniline family compound and jointly utilizing alkali metallic salt and the fourth class ammonia salt. CONSTITUTION:A polyaniline family compound used in the positive electrode of a nonaqueous secondary battery is obtained by oxidative polymerization or oxidative copolymerization of at least a kind of aniline family compound selected from expressions (1)-(3). As a supporting electrolyte of electrolytic solution, alkali metal salt and the fourth class ammonia salt are jointly used. As an alkali metal of alkali metal salt, metals such Li, Na and K can be adopted, however, a Li metal is desirable. The mixture ratio between alkali metal salt and the fourth class ammonia salt is 0.01-0.5mol, preferably within the range of 0.01-0.1mol, for the latter against 1mol for the former. |
