Article Preview

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.
