Abstract
Carbon-containing intercalatable layered or lamellar transition metal chalcogenides having the general formula M.sub.n X.sub.2 C where M is a transition metal selected from the group consisting of Ti, V, Cr, Fe, Zr and Ta; X is sulfur; and n is 1-2; such as TiS.sub.2 C or Ti.sub.2 S.sub.2 C, usable as cathode active materials in alkali metal nonaqueous secondary batteries that can undergo alkali metal intercalation, are synthesized by ion implanting a substrate of the transition metal with sulfur and then carbon at implantation energies in the range of about 150-200 kiloelectron volts and at saturation dosages of 1.times.10.sup.12 to 1.times.10.sup.19 sulfur and carbon atoms/cm.sup.2.
