Abstract
Sub-fluorinated graphite fluorides (CF_x)_n compounds, 0.33 < x < 0.63 were prepared from natural graphite and characterized by TGA, SEM-EDX and XRD. Their cathode behavior in lithium batteries was investigated under different discharge rates and compared to commercial petroleum coke based (CF)_n. At low discharge rate, the energy density increases with the fluorine content x. However, at higher rates, sub-fluorinated compounds performed better than commercial (CF)_n. The result is discussed with relation to higher electrical conductivity of sub-fluorinated compounds.
