Producing an electrically conductive porous carbon material useful as a battery anode material comprises incorporating silicon and/or tin nanoparticles into a polymer matrix and carbonizing the product

摘要

Producing an electrically conductive porous carbon material (I) containing silicon and/or tin comprises incorporating silicon and/or tin nanoparticles into a polymer matrix and carbonizing the product. Independent claims are also included for: (1) (I) produced as above; (2) anode material comprising (I); (3) battery comprising the anode material.
