Long‐life lithium‐ion batteries require materials with well‐designed and controlled structures on nanometer and micrometer scales. Therefore, the hierarchically structured TiO 2 /micron carbon fibers composites (TiO 2 /MCFs) composed of well‐defined nanowires are fabricated through a straightforward impregnation‐calcination process. The unique features, including hierarchically mesoporous micro‐/nanostructures, large specific surface area, and high electrical conductivity endow the TiO 2 /MCFs with convenient lithium‐ion and electron diffusion channels and effective stress−strain relief during repeated electrochemical reaction process. As anticipated, TiO 2 /MCFs deliver an excellent cycling stability with 92 % capacity retention after 5000 cycles at high current density of 2000 mA g −1 , highlighting the great potential for long‐life and fast‐charging lithium‐ion batteries.
