An electrochemical cell is described which has an alkali metal anode, a cathode and a non-aqueous electrolyte which includes: (a) an organic solvent selected from the group consisting of inertly substituted and unsubstituted ethers, esters, sulfones, organic sulfites, organic sulfates, organic nitrites and organic nitro compounds; and (b) electrolytically active alkali metal salts including alkali metal complex anion salts having the formula: ZMRxQy wherein Z is an alkali metal, M is a metal selected from the group consisting ofZn, Cd, B, Al, Ga, In, Tl, Sn, (stannous), P and As, the Rs are certain organic radicals, the Qa are certain heteroatom substituents, x is zero or a positive integer, and y is a positive integer, subject to the proviso that the sum of x plus y is equal to one plus the valance of the metal M. Preferred are the cells having analkali anode, a transition metal chalcogenide active cathode, and an electrolyte as described. |
