What is Two‐Dimensional Layered Metallic VSe 2 /SWCNTs/rGO Based Ternary Hybrid Materials for High Performance Energy Storage Applications about?

## Abstract In this work, the ternary hybrid structure VSe~2~/SWCNTs/rGO is reported for supercapacitor applications. The ternary composite exhibits a high specific capacitance of 450 F g^−1^ in a symmetric cell configuration, with maximum energy density of 131.4 Wh kg^−1^ and power density of 27.49 kW kg^−1^. The ternary hybrid also shows a cyclic stability of 91 % after 5000 cycles. Extensive density functional theory (DFT) simulations on the structure as well as on the electronic properties of the binary hybrid structure VSe~2~/SWCNTs and the ternary hybrid structure VSe~2~/SWCNTs/rGO have been carried out. Due to a synergic effect, there are enhanced density of states near the Fermi level and higher quantum capacitance for the hybrid ternary structure compared to VSe~2~/SWCNTs, leading to higher energy and power density for VSe~2~/SWCNTs/rGO, supporting our experimental observation. Computed diffusion energy barrier of electrolyte ions (K^+^) predicts that ions move faster in the ternary structure, providing higher charge storage performance.
