Abstract:
The invention relates to a process for producing an electrically conductive, porous, silicon- and/or tin-containing carbon material which is suitable in particular for the production of an anode material, preferably for lithium ion batteries; in a first step of the process, preferably crystalline silicon nanoparticles and/or tin nanoparticles and/or silicon/tin nanoparticles are introduced into a matrix based on at least one organic polymer, being more particular dispersed therein, and subsequently, in a second step of the process, the resultant polymer matrix containing the silicon, tin and/or silicon/tin nanoparticles is carbonized to form carbon.
