1. A low voltage electrochemical cell comprising:
a metallic anode comprising an anode metal;
a metallic cathode comprising a cathode metal, the metallic cathode further comprising an anode metal/cathode metal phase composition comprising the anode metal and the cathode metal; an electrolyte disposed between the metallic anode and the metallic cathode; and
a separator within the electrolyte or embedded with electrolyte;
said low voltage electrochemical cell having an open circuit voltage of 1V or less; wherein the electrochemical cell further comprises a voltage stabilization electron current between said metallic anode and said metallic cathode, wherein said voltage stabilization electron current has an amperage that maintains an open load circuit voltage of the electrochemical cell that varies by less than 10 percent over 10 hours or greater.
