Abstract
An electrochemical cell having a lithium based negative active material, an electrolyte in the form of a vitreous cation conductive compound having a formula: aP.sub.2 S.sub.5, bLi.sub.2 S, cLiX, where X stands for chlorine, bromine or iodine, and a, b, and c are numbers chosen in such a manner that b/(a+b) lies in the range 0.61 to 0.70 and c/(a+b+c) is less than or equal to the maximum solubility in the vitreous phase of LiX in the compound aP.sub.2 S.sub.5, bLi.sub.2 S, and a positive active material in the form of a compressed powder with particles of the electrolyte dispersed throughout said positive active material. The positive active material is chosen from the group constituted by: (CH.sub.x ; Cu.sub.d O(PO.sub.4).sub.2 ; V.sub.6 O.sub.13 ; V.sub.2 S.sub.5 ; MoS.sub.3 ; CuS; S; CuO; Cu.sub.3 B.sub.2 O.sub.6 ; FeS.sub.2 ; Pb.sub.3 O.sub.4 ; Bi.sub.2 O.sub.3 ; PbO; BiO(CrO.sub.4).sub.2 ; AgBi(CrO.sub.4).sub.2 ; I.sub.2 ; MoO.sub.3 ; WO.sub.3 ; TiS.sub.2 ; NiPS.sub.3 ; copper bismuthate; and lead bismuthate.
