This patent describes a non-aqueous, electrochemical cell having an active metal anode, a solid active cathode and a liquid electrolyte. It is characterized in that the electrolyte consists essentially of a low vapor pressure, liquid solvate-complex of sulfur dioxide and one or more alkali or alkaline earth metal salts soluble in the sulfur dioxide and also capable of forming a complex therewith, wherein the one or more salts consists essentially of a stoichiometric reaction product of a Lewis acid and a Lewis base, with the equivalent ratio of the one or more salts to SO{sub 2} in the liquid electrolyte ranging from 1:1 to 1:7, and wherein all of the one or more alkali or alkaline earth metal salts is complexed with the sulfur dioxide.
