Klemann, L P; Newman, G H

Electrolyte compositions for reversible alkali metal cells, e.g., lithium batteries, are described which consist essentially of organic solvents selected from the group consisting of inertly substituted and unsubstituted ethers, esters, sulfones, organic sulfites, organic sulfates, organic nitrites, and organic nitrates; and electrolytically active alkali metal salts including organometallic alkali metal salts having the formula ZMR/sub n/, 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 R's are certain organic radicals, and n is a numerical value equal to one plus the valence of the metal M. Rechargeable, high-energy-density electrochemical cells containing an anode having an alkali metal as its active material, a cathode (e.g., one having as its active material a transition metal chalcogenide), and an electrolyte composition of the above type are also described. 3 tables.
