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 carbon-based core having a porous exterior surface and a coating on at least a portion of the porous exterior surface of the core. Such coatings are made from a material that is (i) substantially permeable to at least one type of metal ions or metal atoms, and (ii) substantially impermeable to liquids
