Abstract
A battery electrode composition is provided comprising composite particles, with each composite particle comprising active material and a scaffolding matrix. The active material is provided to store and release ions during battery operation. For certain active materials of interest, the storing and releasing of the ions causes a substantial change in volume of the active material. The scaffolding matrix is provided as a porous, electrically-conductive scaffolding matrix within which the active material is disposed. In this way, the scaffolding matrix structurally supports the active material, electrically interconnects the active material, and accommodates the changes in volume of the active material.
