Abstract
An energy storage composite particle is provided, which includes a carbon film, a conductive carbon component, an energy storage grain, and a conductive carbon fiber. The carbon film surrounds a space. The conductive carbon component and the energy storage grain are disposed in the space. The conductive carbon fiber is electrically connected to the conductive carbon component, the energy storage grain, and the carbon film, and the conductive carbon fiber extends from the inside of the space to the outside of the space. The energy storage composite particle has a high gravimetric capacity, a high coulomb efficiency, and a long cycle life. Furthermore, a battery negative electrode material and a battery using the energy storage composite particle are also provided.
