PURPOSE:To achieve an improved performance of a solid electrolyte battery by using a vitreous solid electrolyte principally composed of lithium oxide, phosphorus pentaoxide and lithium iodide. CONSTITUTION:In a battery having a positive electrode, a negative lithium electrode and a lithium-ion-conducting solid electrolyte, the solid electrolyte consists of a vitreous solid electrolyte principally composed of lithium oxide, phosphorus pentaoxide and lithium iodide. This vitreous solid electrolyte has a higher conductivity than the conventional lithium iodide-alumina solid electrolyte. Besides the electrolyte is stable because lithium iodide is also contained in the vitreous compound containing lithium oxide and phosphorus pentaoxide. Accordingly, the liberation of iodine from the compound is suppressed even at high temperatures, thereby enabling the performance of the battery to be increased. |
