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

Abstract: Conglomerate particles comprising a porous carbon matrix with a plurality of cathode material particles at least partially embedded in the matrix are disclosed, as well as methods for their manufacture using predominantly aqueous chemistry. The conglomerate particles demonstrate surprisingly improved electrochemical properties when used as cathode materials as compared to the cathode material particles when non-embedded.
