Nielsen, N C

A thermal cell having as the fusible electrolyte a mixture of lithium, sodium, and potassium fluorides with a melting point not greater than 600/sup 0/C. The eutectic mixture (46.5 mole percent LiF, 11.5 mole percent NaF, and 42.0 mole percent KF) melting at 454/sup 0/C is preferred. Any chemically compatible anode-cathode combination is used, e.g. a magnesium or lithium-magnesium-aluminum alloy anode and a V/sub 2/O/sub 5/ cathode. Lithium fluoride, sodium fluoride, potassium fluoride, or mixtures of the same may also be added to the cathode or to the cathode and the anode for improved cell life.
