Abstract
A Li/CFx primary battery having a lithium-based anode and a fluorinated carbon cathode. The fluorinated carbon cathode includes fluorinated carbon nanoparticles. The structure and size distribution of the carbon precursor carbon nanotubes are configured to provide improved battery performance. The fluorinated carbon nanoparticles can be formed by fluorinating carbon nanoparticles using a fluorine-based reactive gas at a temperature in the range from 300 to 600° C., and the fluorinated carbon nanoparticles can further be used to form the cathode of the primary battery. Producing the Li/CFx primary batter can also include heating the fluorinated carbon nanoparticles under an inert atmosphere before the fluorinated carbon nanoparticles are used to form the cathode of the primary battery.
