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.

Abstract: A composite material for a battery electrode and a method of producing thereof have been disclosed. In particular, the composite material is used as a cathode for lithium ion batteries. The cathode material is a lithium-rich cathode material with high specific capacity, high capacity retention rate and high lithium ion diffusion. The cathode material is made by a plurality of clusters, in which each of the clusters comprises metallic nano-platelets arranged in a stratified array.
