PURPOSE:To improve the energy density and the cycle life of a battery by using an amorphous inorganic oxide or amorphous inorganic sulfide for the positive pole, a composite body of conductive high polymer and an alkali metal alloy for the negative pole, and an ether-based compound for the solvent of the electrolyte solution. CONSTITUTION:An amorphous inorganic oxide or an amorphous inorganic sulfide for the positive pole, a composite body of a conductive high polymer and an alkali metal alloy for the negative pole, and an ether-based compound for the solvent of the electrolyte solution are used. As the material for the positive pole, an amorphous material manufactured by adding 1.5%mol ratio or less of P2O5 to V2O5, heating, melting and quenching is used. As the composite bodies for the negative pole, a material that can be electrochemically doped to the n-type as the conductive high polymer, and Li or Na-based alloy as the alkali metal alloy is use. As the solvent of the electrolyte solusion, a mixture of one or more kinds of ether-based compound such as 2-MeTHF is used. The volumetric ratio of the ether-based solvent to be added is made 80% or more. |
