PURPOSE:To obtain a secondary battery having high energy density by using alkali metal, alkali metal alloy, conductive polymer, or a composite of alkali metal or alkali metal alloy with conductive polymer in a negative electrode. CONSTITUTION:A negative electrode is formed with alkali metal, alkali metal alloy, conductive polymer, or a composite of conductive polymer with alkali metal or alkali metal alloy. A positive electrode is formed with a composite of conductive polymer with polymer electrolyte. The alloy used in the negative electrode is manufactured by both electrochemical and chemical processes, but the alloy manufactured by electrochemical process is preferable. Thereby, energy density is high, self-discharge rate is low, and discharge voltage is made flat. |
