Ultrafast Nanocrystalline‐TiO₂(B)/Carbon Nanotube Hyperdispersion Prepared via Combined Ultracentrifugation and Hydrothermal Treatments for Hybrid Supercapacitors

Anisotropically grown (b-axis short) single-nano TiO2(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-TiO2(B)/MWCNT composite materials enable ultrafast Li+ intercalation especially along the b-axis, resulting in a capacity of 235 mA h g–1 per TiO2(B) even at 300C (1C = 335 mA g–1).
