    摘要: The invention relates to a carbon material for forming a battery electrode, comprising carbon powder having a homogeneous structure which is produced by causing an organic compound, serving as a ra.w material of a polymer, to deposit onto and/or permeate into carbonaceous particles, and subsequently polymerizing the organic compound, followed by thermal treatment at a temperature of 1,800 to 3,300° C., which comprises a structure which is substantially uniform throughout the entirety of the particle from the surface to the central core where a graphite crystal structure region and an amorphous structure region are distributed. By using the material, a battery having high discharging capacity and low irreversible capacity, with excellent coulombic efficiency and excellent cycle characteristics can be fabricated. The carbon material of the invention may contain carbon fiber filaments. Average roundness, BET specific surface area, true density, laser Roman R value, and average particle size were investigated.

    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.
