Porous titania was synthesized through the spray-drying of titania nanosheets. SEM-FIB analyses showed that the spray-dried nahosheets were spherical particles with no hollow center. Nitrogen adsorption-desorption isotherms showed that the porous titania had a mesoporous structure composed of slit-shaped pores. The porous titania acted as a rechargeable active material for the lithium battery. Rechargeable capacities of about 200 mA h g(-1) (cutoff voltage: 1.0 V) and about 300 mA h g(-1) (cutoff voltage: 0.5 V) could be achieved over the first ten cycles.
