Abstract
Subfluorinated carbonaceous materials obtained through direct fluorination of graphite or coke particles are provided. One set of subfluorinated carbonaceous materials has an average chemical composition CFin which 0.63<x≦0.95, 0.66<x≦0.95 or 0.7<x≦0.95. The subfluorinated carbonaceous materials are capable of electrochemical performance superior to commercial CF at relatively high rates of discharge.
