摘要
Needle-like BiVO4 anode material for Na-ion batteries was prepared by a simple solvothermal technique at 100 degrees C without further calcination. The BiVO4 electrode exhibited initial discharge (sodiation) capacity of 897 mAh/g with coulombic efficiency of 70.68% at 100 mA/g. The average coulombic efficiency was estimated at 93.07% and sodiation capacity predicted at 432 mAh/g upto 200 cycles. The average sodiation/desodiation capacity retention were found to be 52.07 and 68.10%, respectively for more than 100 cycles. The results demonstrate that needle-like BiVO4 anode material offers an excellent electrochemical performance for large-scale energy storage applications.
