Biomass-based activated carbon has great potential in the use of its versatile 3D porous structures as an excellent electrode material in presenting high conductivity, large porosity, and outstanding stability for electrochemical energy storage devices. In this study, the electrode material develops through a novel consolidated carbon disc binder-free design, which was derived from Moringa oleifera leaves (MOLs) for electrochemical double-layer capacitor applications. The carbon discs are prepared in a series of treatments of precarbonized, chemical impregnation of zinc chloride, integrated pyrolysis of N 2 carbonization, and CO 2 physical activation. The physical activation temperatures applied at 650, 750, and 850 °C optimize the precursor potential. By optimizing the 3D hierarchical pore properties of the MOL750, the carbon disc binder-free design demonstrates optimal symmetric supercapacitor performance with a high specific capacitance of 307 F g −1 at a current density of 1 A g −1 in an aqueous electrolyte solution of 1 M H 2 SO 4 . Furthermore, the extremely low internal resistance (0.006Ω) of the carbon disc initiated excellent electrical conductivity. The supercapacitors also maintain their high capacitive properties in aqueous electrolyte solutions of 6 M KOH and 1 M Na 2 SO 4 , respectively. The results show that a novel consolidated carbon disc binder-free design can be obtained from biomass MOLs through a reasonable approach to develop superior electrode materials to enhance high-performance electrochemical energy storage devices.

Biomass‐based porous carbon holds potential for improving the electrochemical performance of supercapacitors due to its high surface area, 2D nanostructure, 3D hierarchical pores, and self‐multi‐doped‐heteroatoms. Here, 2D and 3D porous carbon nanostructures, as well as self‐single‐doped oxygen were successfully obtained from Moringa oleifera leaves waste by a facile, time‐saving, and cost‐effective strategy. The dried powder precursor was chemically provided with 0.5 m/L H3PO4 and ZnCl2 solutions at high‐temperature pyrolysis. Furthermore, electrode material was designed with sleekly slim binder‐free solid coins. The obtained porous carbon has a 2D nanosheet‐nanofiber and rich‐3D hierarchical porous structure with significantly high sub‐ultra micropores. Meanwhile, 17.62 % self‐doped oxygen was found to provide an extra pseudocapacitance effect. The optimum carbon possessed high electrochemical properties at a specific capacitance of 201 F g−1 in 1 M H2SO4 electrolyte. Furthermore, the maximum energy density was obtained at 25 Wh kg−1, at optimum power of 122 W kg−1 in current density of 1.0 A g−1. The electrochemical behavior of these samples was also reviewed through a 1 M Na2SO4 neutral aqueous electrolyte. Therefore, the great potential of Moringa oleifera leaves was observed as a porous carbon source with good material properties for enhancing the performance of electrochemical energy storage devices.

Summary Porous carbon 2D nanosheets (CNSs) with micro‐mesopores interconnected are indispensable for energy conversion systems and storage applications. Herein, we synthesize free‐template highly micro‐mesoporous carbon nanosheet as electrode material for boosting supercapacitor performances. The activated carbon nanosheets derived from bio‐waste were prepared by chemical impregnation followed by high‐temperature pyrolysis without hard/soft/salt template‐assisted and free‐binder adhesives. Garlic skin wastes were selected as a precursor. Furthermore, activated carbon was designed in pellet/coin solids without the addition of binder materials. The porous carbon pellets exhibit a thin 2D nanosheet structure of 15 nm followed by unique wooden labyrinth‐like and rod‐like structures. The result showed that the impregnation of different chemical concentrations increases the surface area to 273% as high as 1002.920 m2 g−1 with a total volume of 1.3270 cm3 g−1. Moreover, the mesoporosity dominated 66.4%, followed by sub‐ultra‐micropores. In the symmetric supercapacitor, the carbon nanosheet boosted the specific capacitance almost 3‐fold to 320.95 F g−1 in the aqueous electrolyte of 1 M H2SO4. The supercapacitor cell has a high energy density of 43.12 Wh kg−1 and power density of 161.99 W kg−1 at a constant current density of 1.0 A g−1. This work proposes a more effective, green, efficient, and controlled approach to obtain bio‐waste‐based porous carbon 2D nanosheet with a controlled pore structure for energy conversion and storage systems. Novelty Statement The novelty of this study is a green synthesis has possessed highly micro‐mesopores nanosheet bio‐waste. 2D nanosheet was prepared free‐template and free‐binder. Sub‐ultra‐micropores were confirmed with dominated mesoporosity of 66.8%. Carbon nanosheet boosted specific capacitance almost 3‐fold to 320.95 F g−1.
