Paper Title:
Synthesis and Evaluation of Electrochemical Properties of Mesoporous Anatase Titania
  Abstract

Lithium intercalation properties were investigated for mesoporous titania, prepared by hydrolysis of titanium tetrabutoxide followed by calcining at various temperatures. X-ray diffraction analysis showed that synthesized titania were anatase phase. The B.E.T. surface area of mesoporous titania decreased with increasing calcining temperature, but that of mesoporous titania calcined at 450°C was over 50 m2/g. Lithium intercalation capacities of mesoporous anatase increased with increasing calcining temperature up to 450°C. Mesoporous anatase titania calcined at 450°C showed a capacity of 118 mAh/g at a current density of 1 A/g. The lithium intercalation properties depended on crystallinity, remaining water content and mesopore size.
