Abstract
A carbon matrix composite material, a preparation method therefor and a battery comprising the same. The carbon matrix composite material comprises micron-sized soft carbon, micron-sized hard carbon, a nano-active material, a first carbon coating layer and a second carbon coating layer, wherein the first carbon coating layer is coated on a surface of the nano-active material to form composite particles; the composite particles are dispersed on the surfaces of the soft carbon and the hard carbon, and in the second carbon coating layer; and the second carbon coating layer coats soft carbon, the hard carbon and the composite particles.
