Abstract

A composite material for a lithium ion battery anode and a method of producing the same is disclosed, wherein the composite material comprises a porous electrode composite material. Pores with carbon-based material forming at the pore wall are created in situ. The porous electrode composite material provide space to accommodate volumetric changes during battery charging and discharging while the carbon-based material improved the conductivity of the electrode composite material. The method creates pores to have a denser carbon content inside the pores and a wider mouth of the pores to enhance lithium ion distribution.
