摘要： 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: ##STR1## wherein R.sub.1 and R.sub.2 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 LiAsF.sub.6, LiBF.sub.4 and LiPF.sub.6 and a solvent, wherein when the supporting electrolyte is LiAsF.sub.6 or LiPF.sub.6, 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 LiBF.sub.4, the solvent is a mixed solvent comprising propylene carbonate, ethylene carbonate and at least one member selected from tetrahydrofuran and 1,2-dimethoxyethane.

摘要： A secondary battery comprised of a positive electrode, a negative electrode and a non-aqueous electrolyte, wherein the positive electrode comprises a sodium-cobalt oxide as the main component, the negative electrode is composed of a composite body comprising a sodium alloy such as a sodium/lead or sodium/tin alloy, a carbon material and a binder, and the non-aqueous electrolyte is composed of a sodium salt and an ether compound. The positive electrode and negative electrode is prepared by a process wherein a binder is swollen with or dissolved in an organic solvent, the swollen or dissolved binder is mixed with a carbon material, and the mixture is then mixed with a sodium alloy or a sodium-cobalt oxide directly or after removal of the organic solvent.
