ABSTRACT:
A thermally activated electrochemical cell utilizes an anode constructed of lemental lithium and transition metal powder. Iron is disclosed to be the best mode of transition metal powder. The cell uses nitrate salt electrolyte containing lithium nitrate and silver nitrate as a cathode enhancer. Electrical performance of this cell includes open circuit potentials of approximately +3.4 volts at 300.degree. C. and thermal activation within the range of 123.degree. to 465.degree. C. Current densities as high as 1,250 mA/cm.sup.2 have been demonstrated.
