| مستخلص: | Herein, 1D layered lithium vanadate (LiVO3) nanorods are successfully synthesized using a facile ultrasonic‐assisted chemical route using V2O5as the starting material. The as‐prepared LiVO3nanorods are characterized by X‐ray diffraction, X‐ray photoelectron spectroscopy, and field emission scanning electron microscopy techniques. The reaction and growth mechanism of LiVO3nanorods formation are provided. The synthesized LiVO3nanorods are used as electrode material for supercapacitor applications and exhibit a high specific capacitance of 426.2 F g−1at 0.5 A g−1. Additionally, the LiVO3// AC asymmetric coin cell supercapacitor device fabricated with LiVO3as the cathode shows an excellent energy density of 25.4 Wh kg−1at a power density of 228.5 Wkg−1along 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 LiVO3is one of the intrinsic reasons that the conductivity and capacitive charge storage performance are greatly improved over V2O5. This design of a 1D layered LiVO3nanorods presented in this work will provide a path to discover high performing electrode materials for supercapacitor applications. Herein, using a facile ultrasonic‐assisted chemical route 1D layered LiVO3nanorods are synthesized and used for the fabrication of asymmetric AC // LiVO3supercapacitor coin cell device. The fabricated aqueous supercapacitor device delivers wide operating voltage window of 1.6 V along with good rate capability for different applied current density values. |
