Fluorine-based cathode materials for thermal batteries

Abstract

A thermal battery can include an anode of lithium alloy; a metal-fluoride cathode; and an electrolyte composition in contact with the anode and cathode. The lithium alloy can be lithium silicone or lithium aluminum. The metal-fluoride cathode includes FeF3, VF3, CrF3, MnF3, CoF3, or a mixture thereof. The metal-fluoride cathode includes a carbon material therein, such as activated carbon, graphite, graphene, carbon nanotube, and combinations thereof. The metal-fluoride cathode can include FeF3, FeF3 and FeS2, CoF3, or CoF3 and CoS2. The metal-fluoride cathode can be devoid of FeS2. The metal-fluoride cathode can further include a metal-sulfide, such as FeS2 or CoS2.
