Popis: A porous titania was synthesized by spray-drying of titania nanosheets exfoliated by (C4H9)4NOH. Nitrogen adsorption-desorption isotherms showed that the porous titania has a mesoporous structure composed of slit-shaped pores. The porous titania acted as a rechargeable active material in a liquid organic electrolyte lithium cell. An initial lithium insertion capacity was about 150 mAh/g (cut-off voltage of 1.0 V), which approximately correspond to the composition of Li0.45TiO2.
