Electrochemical cells having alkali metal anodes and electrolyte salt complex compositions including haloorganometallic alkali metal salt complexes. [TiS/sub 2/ cathode]
Electrochemical cells having alkali metal anodes, e.g., lithium batteries, are described which contain electrolytically active alkali metal salt complexes including haloorganometallic alkali metal salt complexes having the formula ZMR/sub n/K/sub i/, wherein Z is an alkali metal, M is a metal selected from the group consisting of Zn, Cd, B, Al, Ga, In, Tl, Sn (stannous), P and As, the Rs are specified haloorganic radicals, the Xs are selected from various halides, alkyls, aryls, alkaryls, and aralkyls, and n and i are numerical values the sum of which is equal to one plus the valence of the metal M, subject to the proviso that, if n is zero, at least one X is an organic radical. Rechargeable, high-energy-density electrochemical cells containing an anode having an alkali metal as its active material, a cathode having as its active material a transition metal chalcogenide, and in electrolyte composition of the above-described type are also described. 7 tables.
