METHOD FOR PRODUCING A COMPOSITE STRUCTURE COMPOSED OF POROUS CARBON AND ELECTROCHEMICAL ACTIVE MATERIAL

摘要

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.

1. A method for producing a composite structure of porous carbon and electrochemical active material, said method comprising:
a) providing template particles of inorganic template material, each of said particles forming a template framework of interconnected nanoparticles, said template framework containing pores, b) coating the template framework with a coating material that is an electrochemical active material or a precursor thereof, c) infiltrating the pores with a precursor substance for carbon, d) carbonizing the precursor substance to form a carbon layer, and e) removing the template material.
