Multimodal porous CNT@TiO2 nanocables with superior performance in lithium-ion batteries

Multimodal porous CNT@TiO2 core–sheath coaxial nanocables have been constructed by a sol–gel method and post-calcination in the presence of polymer nanotubes acting as a template and carbon source. The composite exhibits excellent electrochemical properties, attaining a high discharge capacity of 231 mA h g−1 at 1000 mA g−1 for up to 110 cycles.
