Herein, 1D layered lithium vanadate (LiVO3) nanorods are successfully synthesized using a facile ultrasonic‐assisted chemical route using V2O5 as the starting material. The as‐prepared LiVO3 nanorods are characterized by X‐ray diffraction, X‐ray photoelectron spectroscopy, and field emission scanning electron microscopy techniques. The reaction and growth mechanism of LiVO3 nanorods formation are provided. The synthesized LiVO3 nanorods are used as electrode material for supercapacitor applications and exhibit a high specific capacitance of 426.2 F g−1 at 0.5 A g−1. Additionally, the LiVO3 // AC asymmetric coin cell supercapacitor device fabricated with LiVO3 as the cathode shows an excellent energy density of 25.4 Wh kg−1 at a power density of 228.5 Wkg−1 along with superior cyclic stability of ≈80% after 5000 cycles and wide operating voltage window of 1.6 V. Density functional theory studies show that the decrease in the bandgap of the LiVO3 is one of the intrinsic reasons that the conductivity and capacitive charge storage performance are greatly improved over V2O5. This design of a 1D layered LiVO3 nanorods presented in this work will provide a path to discover high performing electrode materials for supercapacitor applications. [ABSTRACT FROM AUTHOR] |
