Abstract: A series of silver-modified TiO2 flexible film electrodes with hierarchical 3D nano-network structure are facilely synthesized using hydrothermal method followed via the traditional silver mirror reaction. Successful deposition of Ag nanoparticles on to the TiO2 nanowires surface is confirmed by inductively coupled plasma (ICP) technique, X-ray diffraction (XRD), scanning electron microscope (SEM) with energy-dispersive X-ray analysis (EDX) and transmission electron microscopy (TEM). The electrochemical properties of the Ag@TiO2 nanowires were researched in this work. Our results show that the Ag@TiO2 nanowires with 4.0%(w/w) silver exhibits a better rate performance and more excellent reversibility than pristine one. At different current densities of 50, 100, 200, 400, 800 and 1 200 mA·g-1, the discharge capacities of the Ag@TiO2 electrodes are 261.4, 253.7, 239.5, 216.5, 193.1 and 185.1 mAh·g-1, respectively. After 80 cycles at 200 mA·g-1, its discharge capacity retention is 99.8% indicating Ag@TiO2 electrodes are potentially useful for LIBs. |
