The NiS nanosheets were fabricated using one-step microwave approach with the microwave radiation of 800 W for 1.5 min. Impressively, the NiS nanosheets revealed praiseworthy electrochemical performance, with a capacitance value of 1082.8 F ⋅ g[Formula: see text] at 1 A ⋅ g[Formula: see text] and 77.8% retention over 5000 cycles at 5 A ⋅ g[Formula: see text]. Moreover, an asymmetric supercapacitor was assembled with NiS as the positive electrode and activated carbon (AC) as the negative electrode. It shows 80.42% capacity retention after 8000 cycles and an energy density of 19.45 W ⋅ h ⋅ kg[Formula: see text] at a power density of 801.05 W ⋅ kg[Formula: see text].

We present the design of a high-performance 2 V asymmetric supercapacitor made of graphene-based hybrid nanocomposites in 1 M KOH electrolyte. rGO-CNT-FeOOH (GC-F) was used as the cathode and rGO-CNC-MnO2 (GC-M) as the anode. Both composites well balanced each other in the asymmetric device and gave a high electrochemical performance. The energy density of this ASC is 66.6 W h kg[Formula: see text] at 3.8 kW kg[Formula: see text] power density with an excellent capacitance retention of 88% after 3000 galvanostatic charge-discharge cycles.
