Abstract

Provided is an anode material for an electrode mix comprising a carbon material and a lithium titanium oxide (LTO), wherein a ratio of an average particle size of LTO relative to that of the carbon material is in a range of 0.1 to 20%, and LTO is distributed mainly on a surface of the carbon material. The anode material of the present invention can prevent excessive formation of a SEI film, and is of a high capacity due to a high energy density and exhibits excellent output characteristics and rate characteristics. Further, it has superior electrolyte wettability which consequently results in improved battery performance and life characteristics.
