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 mat...

Zusammenfassung: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).
