Abstract
An electrode includes a conductive substrate and a plurality of conductive structures providing a compressible matrix of material. An active material is formed in contact with the plurality of conductive structures. The active material includes a volumetrically expanding material which expands during ion diffusion such that the plurality of conductive structures provides support for the active material and compensates for volumetric expansion of the active material to prevent damage to the active material.
