“…Further, the phenomenon was also supported by the intercalation of the surfactants. [ 236–238 ] The heterointerface of the prepared composite was understood by the HRTEM image shown in Figure 14b qualitatively distinguishing the overlapping 2D/2D heterostructure of MXene and MoS 2 by scaling the darkness in the lattice fringes, further, the numerical lattice fringe spacings corroborate well with the XRD results suggesting the heterostructure formation. The three‐electrode electrochemical results of the MoS 2 /MXene electrode showed high capacitance of 583 F g −1 at 1 A g −1 possessing stupendous rate performance retaining 82.5% capacitance even at 10 A g −1 , where, higher proportion of energy storage was constituted by MoS 2 possessing higher redox chemical activity.…”

2D interfacial heterostructures have found an unassailable status in energy storage systems, particularly in supercapacitors citing the intriguing structural and electrochemical characteristics. Exactly a decade ago, MXene, a promising 2D transition metal carbide/nitride/carbonitride was found to possess excellent conductivity, hydrophilicity, laudable charge storage opportunities, and enriched surface functionalities conducive for supercapacitors with inherent challenging shortcomings. To substantially improve, assembled 2D/2D MXene heterostructures exhibit commendable performance backed by the fact of swift increase in research interest. In this review, state‐of‐the‐art research progress in material design and electrochemical performance of 2D/2D MXene heterostructures for supercapacitors are investigated. Discussion is initially on MXene fundamentals including synthesis and energy storage governing properties. Particularly, different preparation including electrostatic assembly, in situ growth, hydrothermal treatment, and objective specific strategies and its implications are elaborated. Especially, the electrochemical interface science, electrode–electrolyte interaction and ion/electron dynamics and synergistic enhancement of MXene/rGO, MXene/LDH, MXene/metal sulfides and timely investigations on other 2D MXene architectures are provided for its compatibility from solid‐state to microsupercapacitors for commerciality. To conclude, a well‐comprehended outlook, key challenges, and prospective research guidelines stretching from fundamental mechanism investigations to material and electrolyte optimizations are presented to encourage advanced 2D MXene architectures for future generation supercapacitors.

The demand for energy storage devices with high energy and power densities has increased tremendously in this rapidly growing world. Conventional capacitors, fuel cells, and lithium‐ion batteries have been used as energy storage devices for the long term. However, supercapacitors are one of the most promising energy storage devices because of their high specific capacitance, high power density, and longer cycle life. Recent research has focused on synthesizing transition‐metal oxides/hydroxides, carbon materials, and conducting polymers as supercapacitor electrode materials. The performance of supercapacitors can be improved by altering electrolytes, electrode materials, current collectors, experimental temperatures, and film thickness. Thousands of papers on supercapacitors have already been published, reflecting the significance and elucidating how much demanding such energy storage devices for this fast‐growing generation. This review aims to illustrate the electrode materials loaded on various conductive substrates by electrochemical deposition employed for supercapacitors to provide broad knowledge on synthetic pathways, which will pave the way for future research. We also discussed the basic parameters involved in supercapacitor studies and the advantages of the electrochemical deposition techniques through literature analysis. Finally, future trends and directions on exploring metals/metal composites toward designing and constructing viable, high‐class, and even newly featured flexible energy storage materials, electrodes, and systems are presented.
