- 32 - NONAQUEOUS SECONDARY BATTERY ABSTRACT OF THE DISCLOSURE A nonaqueous secondary battery is disclosed. The positive electrode is composed of a polymer obtained by oxidative polymerization of an aniline compound of the formula: Image (1) and Image (2) wherein R1 and R2 are C1-5 alkyl or C1-5 alkoxy, and X and Y are 0, 1 or 2, or a reduction product of the polymer the negative electrode is composed of (i) an alkali metal, (ii) an alkali metal alloy, (iii) an electroconductive polymer or (iv) composite of an electroconductive polymer with an alkali metal or an alkali metal alloy. The electrolytic solution is composed of a supporting electrolyte selected from LiAsF6 , LiBF4 and LiPF6 and a solvent, wherein when the supporting electrolyte is LiAsF6 or LiPF6 , the solvent is a mixed solvent comprising at least one member selected from propylene carbonate and ethylene carbonate and at least one member selected from tetrahydrofuran and 1,2- dimethoxyethane, and when the supporting electrolyte is LiBF4 , the solvent is a mixed solvent comprising - 33 - propylene carbonate, ethylene carbonate and at least one member selected from tetrahydrofuran and 1,2- dimethoxyethane.
