Abstract

A porous silicon-containing composite includes: a porous core including a porous silicon composite secondary particle; and a shell on at least one surface of the porous core, the shell including a first graphene, wherein the porous silicon composite secondary particle includes an aggregate of a first primary particle including silicon, a second primary particle including a structure and second graphene on at least one surface of first primary particle and the second primary particle, and wherein at least one of a shape and a degree of oxidation of the first primary particle and the second primary particle are different. Also an electrode including the porous silicon-containing composite, a lithium battery including the electrode, and a device including the porous silicon-containing composite or the carbon composite.
