Structural Construction of WO(3) Nanorods as Anode Materials for Lithium-Ion Batteries to Improve Their Electrochemical Performance

WO(3) nanobundles and nanorods were prepared using a facile hydrothermal method. The X-ray diffraction pattern confirms that the obtained samples are pure hexagonal WO(3). Transmission electron microscope images detected the gap between the different nanowires that made up the nanobundles and nanoro...

description WO(3) nanobundles and nanorods were prepared using a facile hydrothermal method. The X-ray diffraction pattern confirms that the obtained samples are pure hexagonal WO(3). Transmission electron microscope images detected the gap between the different nanowires that made up the nanobundles and nanorods. As the anode materials of lithium-ion batteries, the formed WO(3) nanobundles and WO(3) nanorods deliver an initial discharge capacity of 883.5 and 971.6 mA h g(−1), respectively. Both WO(3) nanostructures deliver excellent capacity retention upon extended cycling. At a current density of 500 mA g(−1), the reversible capacities of WO(3) nanobundle and WO(3) nanorod electrodes are 444.0 and 472.3 mA h g(−1), respectively, after 60 cycles.
