title: Hierarchical architectures of TiO2 nanowires--CNT interpenetrating networks as high-rate anodes for lithium-ion batteries.
abstract: Two hierarchical hybrid nanostructures consisting of TiO(2) nanowires /nanoparticles that interact with carbon nanotubes (CNTs) have been designed and synthesized via an in situ solvothermal method, following a simple thermal treatment. The TiO(2) nanowires were grown among the gap in the CNT networks, forming three-dimensional interpenetrating network composites. The TiO(2) nanoparticles adhered to the surface of the CNT to develop a 'coating' CNT network. The two composites with different structures were evaluated as electrodes for lithium-ion storage upon testing in a Li electrochemical half-cell. Compared with the nanoparticle composites, the composite electrodes of the nanowires demonstrated higher capacities (over 150 mA h g(-1) at a current density of 0.5 C) and better rate capabilities (over 80 mA h g(-1) at 10 C) due to its larger surface active sites and shorter diffusion paths for Li(+). These results imply that the special structure is promising as anode materials for energy application.
