Elucidating the Energy Storage Performance of 2D Metallic Vanadium Ditelluride/Carbon Nanotube for Next‐Generation Asymmetric Supercapacitors Using Emerging MoSSe/Carbon Nanotube

Recently, vanadium ditelluride (VTe 2 ) a member of the transition metal ditellurdies family has emerged as a functional material for energy storage applications owing to its exotic intrinsic properties. Similar to most of the nanostructured materials, a hybrid structure of VTe 2 is expected to provide enhanced energy storage capability. Herein, two hybrid structures of VTe 2 are engineered using well‐explored nanocarbons such as RGO and carbon nanotube (CNT) to create a compelling supercapacitor electrode material. Both the hybrid structures show improved electrochemical activity, but VTe 2 /CNT fared better in the charge storage efficiency. The enhanced active sites, short ionic/electronic pathways provided by the CNT network, and the large electric double‐layer contribution have synergized for the inflated capacitance of VTe 2 /CNT. Further, a high‐performance asymmetric supercapacitor (ASC) of VTe 2 /CNT//MoSSe/CNT is constructed in a typical Swagelok cell, and the ASC delivered an energy density output of 36.28 Wh kg −1 at a power density of 463.16 W kg −1 with a remarkable 80.26% capacitance retention. The results of this work suggest that VTe 2 /CNT is a promising contender in the pantheon of functional materials for energy storage applications in the near future.
