A new synthetic route for TiO2(B) via lepidocrocite type KxLiyTi2−(x+y)/4O4 (KLTO) was established. Pure layered titanic acids were obtained by proton exchange of KLTO in 3 mol dm−3 HNO3 and HCl solution. The obtained titanic acid transformed into TiO2(B) phase at 350°C and it was stable up to 450°C. Plate-like morphology particles was formed during proton exchange and transformation process to TiO2(B). TiO2(B) samples with high tapping density (0.9–1.1 g cm−3) was prepared and they delivered discharge capacities of more than 100 mAh g−1 even at 2 C.
