Estimating the term…
Provided is a porous anode active material particle (or multiple porous particles) for a lithium battery, the particle comprising internal pores, having a pore volume of Vp and pore wall surfaces, and a solid portion having a solid volume Va, wherein the volume ratio Vp/Va is from 0.1/1.0 to 10/1.0 and wherein the pores are infiltrated with a graphene material that partially or fully covers the internal pore wall surfaces. The exterior surfaces of graphene-infiltrated porous particles may also be coated with a graphene materials and optionally further coated or encapsulated with a conducting polymer. Also provided is a method of producing graphene-infiltrated porous anode material particles.
