Lithium intercalation properties of octatitanates composed of nanosheets were examined. Several types of nanosheet-octatitanates were prepared by the reassembly of tetratitanate nanosheets in colloidal suspension, which were separated centrifugally at various revolutions, and then by a heat treatment. The colloidal suspension was obtained by the exfoliation of tetrabutylammonium tetratitanate intercalation compound. The capacities of the octatitanates composed of nanosheets were approximately 160 mAh/g, and they were maintained even after the exfoliation and the reassembly. The octatitanate composed of nanosheets with relatively small dimensions centrifugally separated at 6000 rpm exhibited a large capacity of 140 mAh/g at a relatively high current density of 1 A/g. The nanosheet process was found to be effective in improving the high rate capability.
