Solid state cell with alkali metal halo-alkali thiocyanate electrolyte
A novel electrochemical cell is disclosed utilizing: (A) an anode which contains an alkali metal as an anode-active material; (B) a cathode and (C) an electrolyte comprising an electrolytically effective amount of one or more compounds having the formula: (Ax)ma'scn wherein a is an alkali metal, X is a halogen, a' is an alkali metal and 0.1 < or = N < or = 10. Preferred systems include lithium-containing anodes, lithium-containing electrolytes and cathodes which contain cathode-active material selected from the group consisting of cathode-active sulfurs, halogens, halides, chromates, phosphates, oxides and chalcogenides, especially those chalcogenides of the empirical formula mzm wherein M is one or more metals selected from the group consisting of iron, titanium, zirconium, hafnium, niobium, tantalum and vanadium, Z is one or more chalcogens selected from the group consisting of oxygen, sulfur, selenium and tellurium, and M is a numerical value between about 1.8 and about 3.2.
