A method is proposed for inexpensively manufacturing a porous carbon element product of an electrochemically active material, especially for a cathode or anode material of a secondary battery, which has the following method steps: (a) by vapor deposition A template is prepared from an inorganic agent, the template comprising a backbone of nanoparticles and pores connected to each other, (b) an electrochemically active material or a precursor thereof, overlying the template backbone, and (c) a carbon precursor The substance penetrates the pores of the template, (d) carbonizes the precursor material to form a carbon layer, and (f) removes the template. |
