In this work, (Ga1-xZnx)(N1-xOx) (GaZnON) nanowire was in situ synthesized on a graphite layer to improve electrochemical performance in lithium-ion storage. The nanowire structure exhibited fast electron and ion transport with a large surface-to-volume ratio. The GaZnON nanowire anode showed enhanced capacity and stable performance in cycling tests.
In this work, (Ga1-xZnx)(N1-xOx) (GaZnON) nanowire were in-situ synthesized on a graphite layer to generate a morphology for improved electrochemical performance in lithium-ion storage. This hybrid structure exhibited a large surface-to-volume ratio with fast electron and ion transport. The electrical conductivity of GaZnON nanowire was revealed by Hall Effect measurements. The GaZnON nanowire anode delivered a high capacity of 878.2 mA h g(-1) at 0.1 A g(-1) after 200 cycles, increased by 144% relative to a GaZnON powder anode. After 200 0 cycles at 2.0 A g(-1), the discharge capacity was maintained at 326.6 mA h g(-1). The nanowire-based morphology was demonstrated as the origin of the fast charge transfer kinetic and improved pseudocapacitive. The ex-situ XRD and XPS measurements demonstrated the structural stability and reversible lithium-ion intercalation mechanism of GaZnON nanowire. This work provides a simple strategy for controllable GaZnON nanowire preparation, and also a deeper mechanism analysis to understand the lithium-ion storage process of GaZnON nanowire.
