Summary: This study focuses on developing high-performance asymmetric hybrid supercapacitors (AHSs) by combining two-dimensional Cu-Cr phosphate (CCP) and layered reduced graphene oxide (rGO). The resulting CCPG nanohybrids exhibit mesoporosity, high surface areas, and fast charge transfer kinetics. The optimized CCPG electrode demonstrates enhanced physiochemical and electrochemical properties, delivering higher specific capacity and excellent cycling stability within a widened potential window. This hybridization approach can be applied to develop various nanohybrids of other metal dichalcogenide phosphates and rGO.

Summary: In this study, a novel approach of preparing a composite supercapacitor electrode consisting of ternary metal oxide nano-structure decorated with transition metal sulfide is presented. The hybrid structure reveals superior electrochemical performance, and the thinner and well-connected nanosheets of NiCo2O4 provide more interface between the electrode and the electrolyte. The high areal capacitance and enhanced rate capability of the optimized NiCo2O4-MoS2 composite are attributed to the synergistic effect of high-surface area of the oxide nano-sheets and better electronic conductivity of the sulfide.
