Abstract
Novel solid electrolyte compositions and novel electrochemical cells utilizing the novel electrolyte compositions are disclosed. The cells utilize: (a) an anode which contains as the anode-active material an alkali metal; (b) a cathode which contains as the cathode-active material a chalcogenide of the empirical formula M'A.sub.p wherein M' is one or more metals selected from the group consisting of titanium, zirconium, hafnium, niobium, tantalum and vanadium, A is one or more chalcogens selected from the group consisting of oxygen, sulfur, selenium and tellurium, and p is a numerical value between about 1.8 and about 3.2; and (c) a novel solid electrolyte composition which comprises one or more lithium-halogen-aluminum sulfate compounds of the formula LiI. x[Al.sub.2 (SO.sub.4).sub.3. nH.sub.2 O] wherein x is a numerical value representing the number of moles of Al.sub.2 (SO.sub.4).sub.3. nH.sub.2 O per mole of LiI, and wherein n is a numerical value representing the number of moles of H.sub.2 O per mole of Al.sub.2 (SO.sub.4).sub.3, i.e., the extent of hydration of the compound.
