Hollow TiO 2 is synthesized through hydrolysis of titanium tetraisopropoxide on CaCO 3 templates to facilitate lithium ion insertion into and extraction from the TiO 2 bulk. The hollow TiO 2 is capable of delivering 255.9 mAh g −1 with excellent cycling performance. The lithiation mechanism of the TiO 2 anode is investigated using an in situ Raman spectroscopic imaging technique.
