SOLID ELECTROLYTE BATTERY AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To enhance the discharge characteristic of a solid electrolyte battery having a polymeric solid electrolyte between positive and negative electrodes and to suppress deterioration of electrode materials caused by charge and discharge to provide the battery with excellent charge/discharge and charge- discharge cycle characteristics by enabling the battery to be charged and discharged at large currents even when used as a secondary battery. SOLUTION: This solid electrolyte battery has a polymeric solid electrolyte between positive and negative electrodes. They are aligned so that the particle diameters of electrode materials in the positive and/or negative electrode are large at their interfaces with the polymeric solid electrolyte and small on the opposite side to the interfaces, and a fluidized material for the polymeric solid electrolyte is supplied to the electrode material where the particle diameters are large, and is hardened to form the polymeric solid electrolyte.
