PURPOSE:To provide a solid secondary battery having excellent discharge characteristic and self-discharging characteristic by using sheprel phase compound such as Cu-sheprel and Fe-shaprel to a positive and a negative electrode, adding thereto a solid electrolyte of RbCu4IxCly series, and performing crushing and mixing under heating, and thereby coating the surfaces of particles as electrode material with electrolyte thinly and uniformly. CONSTITUTION:As electrode material working as a positive and a negative electrode, sheprel phase compound such as Cu-sheprel (CuyMo6S8-z) and Fe- sheprel (FeyMo6S8-z) is used, and to this powder a solid electrolyte of RbCu4 IxCly series is added, and the resultant is subjected to crushing and mixing under heating. At this time, heating temps. between 100-250 deg.C are used. The electrolyte content shall be 10-50wt.% of the electrolyte material. At this time, the ambient atmosphere shall contain a minimum possible moisture, which should be favorable for avoiding degradation of the electrolyte. |
