ABSTRACT:
A method for making a chalcogenide cathode usable in secondary batteries comprises sputtering molecules of an intercalatable layered transition metal chalcogenide cathode active material, such as a titanium sulfide, onto and into a high porosity current collector substrate, such as nickel foam, by impinging a primary beam of argon ions onto a workpiece or target of the material and directing a secondary beam of sputtered molecules of the material at the substrate.
