    Abstract: Provided herein are composite materials for use in an electrical energy storage system (e.g., high-capacity batteries) and methods for preparing the same. The composite materials of the present disclosure comprise a three-dimensional carbon network and optional silicon particles. The composite materials further comprise macropores, at least some of which are formed by carbonizing sacrificial particles dispersed throughout a three-dimensional network. The macropores advantageously provide a space to accommodate the strain and stress in the electrode structure due to volume changes of silicon (particles) during charging and discharging of the electrical energy storage systems.
