Synthesis of Nanocomposite with Carbon-SnO2-Ga2O3 on TiO2 Nanotubes and Application in Lithium Ion Batteries

Currently, demands for rechargeable batteries are increasing for applications in mobile devices, electric-powered transportation, and stationary energy storage. For these applications, lithium ionbatteries (LIBs) have been the most promising system due to their long cycle life, high energy density, safety, and so on [1]. In the present work, we have employed a simple process of anodizing Ti foils to prepare TiO2 nanotube arrays which show enhanced electrochemicalproperties for applications as Li-ion battery electrode materials [2]. Through the introduction of well-distributed tin oxide nanocrystals on the surface of pre-prepared TiO2 nanotubes and followed by carbon coating, a novel TiO2/SnO2- Ga2O3-C. As an anode material of Li-ionbatteries (LIBs), NTs exhibit excellent long-term cycling stability and satisfactory rate capability, which are ascribed to the synergetic effects of a unique combination of material properties in the well-designed conductive matrix [3]. Electrode performance was tested bycharge/discharge galvanostatic and cyclic voltammetry experiments. The structure of nanotube titanium oxide will be studied by scanning electron microscope (SEM).
