Abstract

In this study, two new layered titanates, fibrillar TiO 2· (CH 3COOH) 1.4 and chrysanthemum-like TiO 2·(CH 3COOH) 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 TiO 2 with high TiO 2-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 TiO 2-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.
