Abstract
Core/shell, indium tin oxide (ITO)/TiO2 hybrid nanostructured electrodes for high-power lithium ion rechargeable batteries have been synthesized via a thermal evaporation method followed by pulsed laser deposition (PLD). Lithium-active TiO2 nanoparticles were uniformly assembled onto highconductivity ITO nanowire arrays that were directly grown on metallic current collectors. This configuration resulted in superior rate capabilities and long-term cycle life. Such high electrochemical performances result from the unique 3 dimensional (3D) geometrical features of nanoarchitectured electrodes, which enable efficient electronic pathways upon prolonged cycling.
