SnO(2) Quantum Dots Distributed along V(2)O(5) Nanobelts for Utilization as a High-Capacity Storage Hybrid Material in Li-Ion Batteries

In this study, the facile synthesis of SnO(2) quantum dot (QD)-garnished V(2)O(5) nanobelts exhibiting significantly enhanced reversible capacity and outstanding cyclic stability for Li(+) storage was achieved. Electrochemical impedance analysis revealed strong charge transfer kinetics related to that of V(2)O(5) nanobelts. The SnO(2) QD-garnished V(2)O(5) nanobelts exhibited the highest discharge capacity of ca. 760 mAhg(−1) at a density of 441 mAg(−1) between the voltage ranges of 0.0 to 3.0 V, while the pristine V(2)O(5) nanobelts samples recorded a discharge capacity of ca. 403 mAhg(−1). The high capacity of QD-garnished nanobelts was achieved as an outcome of their huge surface area of 50.49 m(2)g(−1) and improved electronic conductivity. Therefore, the as-presented SnO(2) QD-garnished V(2)O(5) nanobelts synthesis strategy could produce an ideal material for application in high-performance Li-ion batteries.
