This patent describes a substantially moisture free electrochemical cell. It comprises: a lithium anode, an inorganic electrolyte including sulfur dioxide that provides a solvent for lithium tetrachloroaluminate and at least one alkaline earth tetrachloroaluminate and that functions in conjunction with dissolved aluminum and lithium to produce a discharge product and in which solution there is a mole equivalent ratio of lithium to alkaline earth to sulfur dioxide within the range of from 1 to 1 to 9, to lb 2 to 12, the cell having a cathode supported on a current collector, and the cathode consisting of a porous carbon for supporting the discharge product.
