NEW ELECTRODE-ACTIVE MATERIAL FOR ELECTROCHEMICAL ELEMENTS

摘要

The invention relates to a method for producing active material for the electrode of an electrochemical element, comprising the steps of (1) providing carbon particles, (2) applying a silicon precursor onto the surface of the carbon particle and (3) thermally breaking down the silicon precursor to form metal silicon. The invention furthermore relates to an electrochemical active material that can be produced according to a said method, to an electrode having said active material, and to an electrochemical element having at least one said electrode.
