Abstract
A battery electrode material composed of a composite material including fiber agglomerates having micro-pores and an electrode active material included within the micro-pores of the fiber agglomerates. The agglomerates are formed by tangled masses of vapor-grown carbon fibers having fiber contact points. Furthermore, at least a portion of the fiber contact points are chemically bonded fiber contact points. Also disclosed is a secondary battery including electrodes made from the battery electrode material.
