Anisotropically grown ( b ‐axis short) single‐nano TiO 2 (B), uniformly hyper‐dispersed on the surface of multiwalled carbon nanotubes (MWCNT), was successfully synthesized via an in situ ultracentrifugation (UC) process coupled with a follow‐up hydrothermal treatment. The uc‐TiO 2 (B)/MWCNT composite materials enable ultrafast Li + intercalation especially along the b ‐axis, resulting in a capacity of 235 mA h g –1 per TiO 2 (B) even at 300C (1C = 335 mA g –1 ).
