摘要： A titania-carbon-sulfur composite including a titania-carbon composite prepared by mixing cylindrical carbon materials and titania (TiO2-x), in which some oxygen is reduced (i.e., x is less than 2), to have a structure in which cylindrical carbon materials are entangled and interconnected in three dimensions; and sulfur introduced into at least a part of the external surface and inside of the titania-carbon (TiO2—C) composite, and a method for preparing the same.
