Summary: This study addresses the issue of poor performance in assembled supercapacitor devices, which is attributed to the slow kinetics and structural instability of positive electrodes and the lower capacitance of carbon-based negative electrodes. To solve this challenge, the authors propose a sustainable solution using Ag-embedded CoFe-phosphate (CFPAg) and Ti3C2 MXene as positive and negative electrodes, respectively, to create a hybrid supercapacitor (HS) device. The CFPAg electrode shows a specific capacity of 1021 mF/cm2 with 80.5% cyclic stability over 10,000 cycles, while the MXene electrode displays a specific capacity of 177.6 mF/cm2 with a cyclability of 84.7% over 10,000 cycles. The HS device fabricated using CFPAg and MXene electrodes exhibits an areal capacitance of 79.6 mF/cm2 and provides excellent cyclic stability of 96% over approximately 39,000 cycles. It also demonstrates a high energy density of 24.7 μWh/cm2 at a power density of 0.75 mW/cm2 when measured at 2 mA/cm2 applied current density. This work serves as a foundation for developing a range of electrode materials for next-generation energy storage devices, providing a sustainable and effective solution to improve supercapacitor device performance and longevity.
