PURPOSE:To provide a solid electrolyte battery having a solid electrolyte which is high in ion conductivity and is chemically stable and so highly reliable. CONSTITUTION:A solid electrolyte battery D comprises a positive electrode 2, a negative electrode 3 made from metal lithium or its alloy, and a solid electrolyte 1 made from a polyethylene oxide, polysiloxane and an ion- dissociating metal salt. Preferably, the solid electrolyte is molded with 3 to 30 parts by weight of the ion-dissociating metal salt blended into 100 parts by weight of a mixture comprising 97 to 75 parts by weight of the polyethylene oxide and 3 to 25 parts by weight of polysiloxane. The solid electrolyte battery having a high electromotive force and a high discharge capacity, being excellent in a cycle characteristic so as to be chemically stable and highly reliable even in use for a long period, and exhibiting battery performance over a wide temperature range can thus be obtained. |
