Abstract
A composite particle for electrode includes a carbon matrix, a plurality of active nanoparticles and a plurality of graphite particles. The active nanoparticles are randomly dispersed in the carbon matrix. Each of the active nanoparticles includes an active material and a protective layer. The protective layer covers the active material, and the protective layer is an oxide, a carbide or a nitride of the active material. The graphite particles are randomly dispersed in the carbon matrix. A volume fraction of the protective layer in each of the active nanoparticles is smaller than 23.0%.
