Abstract:
The present invention provides a carbon-silicon composite material suitable (e.g., high capacity; small irreversible capacity; long cycle life) to be used as a negative electrode material for battery. The carbon-silicon composite material comprises a carbon black and a silicon particle, wherein the carbon black and the silicon particle are bound via a resin thermolysis product.
