Abstract
A process is disclosed for producing fluorinated carbon (CF.sub.x) admixed which can be used in a lithium battery to eliminate low voltage at the beginning of discharge. The process uses a thick carbon bed to assure proper degree and type of underfluorination of the CF.sub.x. The inhomogeneous fluorinated carbon produced is a fully, or overfluorinated CF.sub.x with a small amount of underfluorinated material to eliminate voltage suppression in Li/CF.sub.x batteries.
