TiO2-B/Ag Nanocomposite Wires Enhanced Electrochemical Performance for Li-ion Batteries
In this work, the pristine and Ag-composited TiO2-Bronze (TiO2-B) nanowires are successfully synthesized by hydrothermal method using anatase(P25) as titanium source. The SEM, TEM results reveal that the silver particles are well distributed on the TiO2-B nanowires. Also, the TiO2-B/Ag nanowires are dispersed very well, which demonstrate more Li-ion insertion/extraction hosts exposed to the electrolyte. Moreover, the electrochemical performance tests suggest that compared with the pristine TiO2-B, the Ag-composited TiO2-B (TiO2-B/Ag) shows remarkably higher capacities (~286mAhg-1, closing to the theoretical capacity) and superior rate capability. The reasons causing this performance difference are ascribed to the added silver particles, which could reduce the Li-ion diffusion length and improve the material electrical conductivity.
