PURPOSE:To suppress increase in positive electrode potential in a high charge state and increase flatability of voltage in discharge by using polyaniline as positive active material and a salt containing bromine ion or iodine ion as electrolyte. CONSTITUTION:Polyaniline is formed by oxidation polymerization of aniline, and used as a positive electrode. Lithium, polyaniline, or graphite is used as a negative electrode. LiBr/propylene carbonate of LiI/propylene carbonate is used as electrolyte. By using these materials, a secondary battery is formed. By using a salt containing bromine or iodine ion as electrolyte, potential increase in a polyaniline positive electrode in charging is suppressed, and flatability of voltage in discharge is increased to obtain an efficient polymer battery. |
