“…Hence, the energy density can be increased either by increasing the specific capacitance of the electrode or by increasing the potential window of electrolytes. A large volume of research work was done on either aspect by making new electrode materials with ultrahigh specific capacitance like MXenes − and by using wide-voltage-window nonaqueous electrolytes. − …”

A wide-operating-voltage asymmetric supercapacitor (ASC) based on an aqueous electrolyte has great promise in the current energy storage technologies by providing better energy density, power density, safety, cost effectiveness, and long cycle life. Herein, the fabrication of an ASC using a 2D transition metal dichalcogenide (molybdenum disulfide (2D MoS 2 )) and a transition metal oxide (vanadium pentoxide, V 2 O 5 ) as the negative and positive electrode, respectively, was demonstrated. The electrochemical and galvanostatic charge−discharge analysis of both positive (V 2 O 5 ) and negative electrodes (2D MoS 2 ) was carried out in a threeelectrode setup. The results show stable operating potentials of −0.9 and 1.0 V for MoS 2 and V 2 O 5 electrodes, respectively. By combining these positive and negative electrodes in a 1 M sodium sulfate (Na 2 SO 4 ) aqueous electrolyte, the developed ASC reveals a wide operating potential (2.0 V). The electrochemical analysis of the ASC in a stable operating potential of 1.4 V gives an areal capacitance and energy density of 30 mF/cm 2 and 8.2 μWh/cm 2 , respectively, at a scan rate of 1 mV s −1 . The performance of the ASC was analyzed for 5000 continuous charge−discharge cycles at a higher current of 3.5 mA. After 5000 cycles, the ASC exhibits more than 80% capacitance retention with a specific capacitance of 0.85 mF/cm 2 .
