PROBLEM TO BE SOLVED : To provide a new anode material for a lithium-ion battery. SOLUTION : The present invention relates to an anode material for a lithium-ion battery. The anode material for the lithium-ion battery is represented by a molecular formula : MxNyTizO(x+3y+4z)/2, where : 0≤x≤8, 1≤y≤8, and 1≤z≤8; M is alkali metal selected from Li, Na, and K; and N is a group VA element selected from P, Sb, and Bi or rare earth metal selected from Nd, Pm, Sm, Eu, Yb, and La. The anode material of the present invention has de-lithiation potential of 0.8 to 1.2 V vs. Li+/Li, and has a better potential plateau, better cycle performance, and better output-input properties, than a titanium-based anode material.
