ABSTRACT:
Alkaline earth metal anode cells having an intercalation cathode, a nonaqueous liquid electrolyte comprising (a) an organic solvent, for instance, an ether, an ester, a sulfone, an organic sulfide, an organic sulfate, a tertiary amine, an organic nitrite, and an organic nitrate, and (b) at least one of an electrolytically active alkaline earth metal salt comprising an organometallic alkaline earth metal salt represented by the formula: ##STR1## wherein Z is selected from the group consisting of boron and aluminum; X is selected from the group consisting of phosphorus and arsenic; M is an alkaline earth metal; and in which R.sub.1 -R.sub.6 are radicals independently selected from the following groups: alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, allyl, heterocyclic alkyl, and cyano, with the proviso that R.sub.1 -R.sub.6 cannot be all alkyl or all aryl and triarylalkylborate or aluminate anions, and trialkylarylborate or aluminate anions are excluded and M represents an alkaline earth metal.
