ABSTRACT:
A thermal battery (10) includes a heat source (16) fabricated from a combination of metallic lithium and a predominantly fluorine substituted hydrocarbon (PFSH) material. In some embodiments the thermal battery (10) includes a combination anode/heat source (62) fabricated from metallic lithium and a polymeric or telomeric PFSH material to provide a lithium based anode with integral heating capability for activating the thermal battery (10). In other embodiments, the anode/heat source (62) is fabricated from other light weight materials having high electromotive potential such as sodium, potassium, calcium, or magnesium, in combination with a predominantly fluorine substituted hydrocarbon.
