In this study, two new layered titanates, fibrillar TiO₂·(CH₃COOH)_1.4 and chrysanthemum-like TiO₂·(CH₃COOH)_0.9 (named as FT and CT) with acetic acid and acetate intercalation have been synthesized by reacting titanium isopropoxide (TTIP) with acetic acid at different temperatures. Furthermore, nano/micro hierarchical structure TiO₂ with high TiO₂-B/anatse ratio was obtained by annealing the titanate (CT). For use as an anode for lithium ion batteries, uniform carbon coated titanium dioxide with high TiO₂-B content was obtained by “self-carbonizing” CT under argon atmosphere at 350 °C, and the compound was named SC-CT350. The capacity of the anode made from SC-CT350 can reach 144 mA h g⁻¹ under a high charging/discharging rate (10 C) and showed excellent retention ability.The research was conducted at the NSRRC beamline 01C2 .
