Abstract
A secondary electrochemical cell comprising a solid anode, an electrolyte and a cathode. The anode is a solid solution of silver and a metal which is an alkaline or alkali earth metal. The metal is capable of forming a solid solution with the anode on the recharging of the anode. Alternatively, the cell is formed in the discharged state with a solid porous silver anode, a cathode, a nonaqueous liquid electrolyte containing the alkaline or alkaline earth metal salts therein. The alloyed anode improves the rechargeability of the cell.
