SnO Quantum Dots Distributed along VO Nanobelts for Utilization as a High-Capacity Storage Hybrid Material in Li-Ion Batteries.

In this study, the facile synthesis of SnO quantum dot (QD)-garnished VO 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 VO nanobelts. The SnO QD-garnished VO nanobelts exhibited the highest discharge capacity of ca. 760 mAhg at a density of 441 mAg between the voltage ranges of 0.0 to 3.0 V, while the pristine VO nanobelts samples recorded a discharge capacity of ca. 403 mAhg. The high capacity of QD-garnished nanobelts was achieved as an outcome of their huge surface area of 50.49 mg and improved electronic conductivity. Therefore, the as-presented SnO QD-garnished VO nanobelts synthesis strategy could produce an ideal material for application in high-performance Li-ion batteries.
