Modification with transition metal compounds is an effective strategy to improve the capacitance of biomass derived carbon. In this work, high‐performance (Ni,Co)Se/banana leaves derived carbon ((Ni,Co)Se/BLC) composite with 3D porous structure was prepared by two‐step carbonization and subsequent hydrothermal reaction process. The prepared (Ni,Co)Se/BLC exhibits a high specific capacitance of 840.6 F/g at a current density of 1 A/g, which is more than five times comparing with the carbon matrix. Asymmetric supercapacitor, assembled with the (Ni,Co)Se/BLC composite as the positive electrode and BLC as the negative electrode, exhibits a wide potential window of 1.5 V, delivers a high energy density of 34.3 Wh/kg at a power density of 749.8 W/kg, and the power density can reach 7500 W/kg at the energy density of 19.4 Wh/kg. The results reveal that the modification of metal selenide can greatly improve the electrochemical properties of biomass derived carbon, which is significant for the application of biowaste in supercapacitor electrode materials.

Supercapacitors have garnered substantial interest owing to their capacity to deliver power effectively for short-term applications. However, current supercapacitors suffer from limited stability and low-capacity storage. Metal-organic frameworks (MOFs) have emerged as a promising solution due to their high surface area and abundant active redox sites. MOF-based electrodes combined with aqueous based electrolytes have shown potential to enhance supercapacitor performance. While there is limited literature on MIL-101(Fe) MOF-based electrodes, a comparative study was conducted to investigate the supercapacitor performance of MIL-101(Fe) electrodes synthesized using hydrothermal and microwave-assisted processes. Processing parameters, such as the method used, alter the microstructure, morphology, and uniformity of supramolecular chemistry, impacting electrochemical characteristics. This study aimed to determine the active redox reactions, chemical stability, surface area, adsorption characteristics, and electrochemical characteristics of the electrodes. The electrodes from hydrothermal synthesis [MF(ht)] exhibited excellent electrochemical activity in comparison to the microwave-assisted [MF(m)] electrodes in the three-electrode configuration. At a high current density of 7 A/g, the MF(ht) electrode displayed a remarkable specific capacitance of 775.6 F/g and a good cyclic stability (82% @ 10 A/g) after 5000 galvanostatic charge–discharge cycles. At a current density of 1 A/g, the two-electrode configuration of MF(ht) yielded a high energy density of 74.7 Wh/kg at a power density of 2160 W/kg and a decent cyclic stability after 5000 cycles. The results suggest that the MF(ht) electrodes possess remarkable electrochemical properties that make them a promising candidate for advanced applications in energy storage.
