Article Preview

Thin films of titanate were prepared by electrophoretic deposition (EPD) of a colloidal suspension of nanosheets, and their lithium intercalation properties were examined. Thickness of the obtained film increased approximately in proportion to the increase in deposition time and concentration of the colloidal suspension used for EPD bath. EPD method was revealed to be a convenient method for layer lamination of nanosheets. The reversible capacity for the obtained film was approximately 170 mA h g-1, and it was in common with anatase-type TiO2 or conventional titanate. Lithium diffusion coefficient along the thickness direction was estimated to be 6 × 10-14 cm2 sec-1.
