چکیده انگلیسی
Sub-fluorinated graphite fluorides (CFx)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.
