Abstract

In order to provide an inexpensive product composed of a porous carbon provided with electrochemical active material, said product being suitable particularly for use as a cathode or anode material for a secondary battery, a process comprising the following process steps is proposed: (a) producing a template from inorganic material by gas phase deposition, said template comprising a framework of pores and nanoparticles joined to one another, (b) coating the template framework with an electrochemical active material or a precursor thereof, (c) infiltrating the pores of the template with a precursor substance for carbon, (d) carbonizing the precursor substance to form a carbon layer, (f) removing the template.
