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) ).
通过原位超离心（UC）过程与后续水热处理相结合，成功合成了沿 b 轴（b 轴短）各向异性生长的单纳米 TiO2（B）均匀超分散在多壁碳纳米管（MWCNT）表面上。uc-TiO2（B）/MWCNT 复合材料能够实现超快 Li（+）嵌入，特别是沿 b 轴，即使在 300°C（1C=335 mA g（-1））下，TiO2（B）的容量也达到 235 mA h g（-1）。
