A thermal battery cell with a fiberglass wrapping and facial pressure as a eans for wetting the calcium anode to prevent deflagration or flashing using either a homogeneous LiClO.sub.4 and AgNO.sub.3 electrolyte or a non-homogeneous electrolyte arrangement of LiCl, LiNO.sub.3 and AgNO.sub.3.

Thermal cell non-deflagration design

This invention comprises a method of synthesizing ternary phosphide compos of the general formula M(II)M(IV)P.sub.2 by fused salt electrolysis in which a melt powder mixture containing phosphorus compounds is introduced into an electrolytic apparatus containing a liquid group II metal cathode and a group IV metal or semiconductor source. Electrolysis occurs under controlled conditions in which oxygen is excluded as an impurity to produce the desired ternary phosphide compounds.

An ambient temperature thermal battery having two relatively high temperature melting electrolytes which form a low melting temperature electrolyte upon activation.

Ambient temperature thermal battery

A thermally activated electrochemical cell utilizes a lithium-boron anode and a molten nitrate electrolyte selected from the group consisting of lithium nitrate, a mixture of lithium nitrate and sodium nitrate, a mixture of lithium nitrate and potassium nitrate, and a mixture of lithium nitrate and sodium nitrate with potassium nitrate, to provide improved cell electrical performance. The electrolyte is contained on a fiberglass separator and the electrolyte adjacent to the cathode may contain silver nitrate as well. Current densities over 300 mA/cm.sup.2 with a usable temperature range of over 150.degree. C. have been obtained. Anode open circuit potentials of about 3.2 V were found with little polarization at 100 mA/cm.sup.2 and with very slight polarization at 300 mA/cm.sup.2.

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.
