Abstract
A battery electrode composition is provided that comprises composite particles. Each composite particle may comprise, for example, active fluoride material and a nanoporous, electrically-conductive scaffolding matrix within which the active fluoride material is disposed. The active fluoride material is provided to store and release ions during battery operation. The storing and releasing of the ions may cause a substantial change in volume of the active material. The scaffolding matrix structurally supports the active material, electrically interconnects the active material, and accommodates the changes in volume of the active material.
