The present invention relates to an anode material for a battery and a preparation method thereof, and particularly to surface-treated carbon that has a large capacity and superior room temperature and high temperature cycle life properties, and that comprises a carbon core and a coating layer containing a fluorine-type organometal salt, and thus can be used as an anode material for a battery; and a preparation method thereof. A lithium or lithium ion secondary battery comprising the surface-treated carbon as an anode material has improved high temperature cycle life properties and stability.
