Abstract: PURPOSE: A method for preparing one-dimensional titanium oxide nanotubecluster anode active material for lithium rechargeable batteries is provided to improve the capacity through the increase of a lithium insertion coefficient to titanium oxide nanotubecluster by improving reaction area with electrolyte. CONSTITUTION: A method for preparing one-dimensional titanium oxide nanotubecluster anode active material for lithium rechargeable batteries comprises the steps of: performing hydrothermal synthesis of spherical titaniumoxide micro powder in strong alkali solution; controlling the pH value of the hydrothermally synthesized titanium oxide nanotubecluster; and heat-treating the titanium oxide nanotubecluster in which the pH value is controlled.
