Mesoporous single-crystal-like TiO2 mesocages threaded with carbon nanotubes for high-performance electrochemical energy storage

A novel nanocomposite based on mesoporous single-crystalline TiO2 particles (TiO2 mesocages) threaded with carbon nanotubes (CNTs) has been successfully synthesized via a facile solvothermal method. The unique hybrid architecture endows the nanocomposite with facile ion and electron transport pathways, abundant active surface sites and high structure robustness. As a result, remarkable electrochemical lithium storage properties in terms of high capacity, excellent rate capability and ultra-stable long-term cycling performance have been achieved by the CNTs-threaded TiO2 mesocages.
