An energy storage composite particle, having a carbon film, a conductive carbon component, an energy storage grain and a conductive carbon fiber, is provided. The carbon film is surrounded to from a space. The conductive carbon component and the energy storage grain are disposed in the space. The conductive carbon component, the energy storage grain and the carbon film are electrically connected with each other by the conductive carbon fiber, and the conductive carbon fiber is extended from the inside of the space to the outside of the space. The energy storage composite particle has high capacity, high coulomb efficiency and long cycle life. Besides, a battery anode material and a battery with the above energy storage composite particles are also provided.
