“…In addition, the unclear concentric rings in the SAED pattern are estimated with the radius of ~4.76 and 2.94 1/nm, which are connected to the (100) and (002) planes, respectively. Herein, KOH activation proves effective in inducing a honeycomb-like morphology with interconnected macropores in coconut shellderived carbon [23,34]. This network of interconnected macropores serves to facilitate electrolyte ions into the mesopores/micropores, thereby expediting their access to the carbon materials surfaces.…”

“…However, the consumption of organic polymers, fossil fuels and templates unavoidably increases the price of HPACs synthesis, further hindering their broad use in supercapacitors. Biowaste materials, including pitaya peel [20], corncob [21], biooil [22], durian kernel [23] and sesame husk [24], have been employed to create HPACs on an industrial large-scale and also served as electrode materials in supercapacitors due to their unignorable benefit of low cost [25]. Among various biowaste-based supercapacitors, zinc-ion hybrid supercapacitors (ZHSs) directly utilize naturally abundant zinc foils as the anode, biowaste-derived carbons as the cathode materials and neutral electrolytes (ZnSO 4 or Zn(CF 3 SO 3 ) 2 ) for a comparatively high working voltage (~1.8 V in the aqueous electrolyte) [26,27].…”

In this research, we successfully produced hierarchical porous activated carbon from biowaste employing one-step KOH activation and applied as ultrahigh-performance supercapacitor electrode materials. The coconut shell-derived activated carbon (CSAC) features a hierarchical porous structure in a honeycomb-like morphology, leading to a high specific surface area (2228 m2 g−1) as well as a significant pore volume (1.07 cm3 g−1). The initial test with the CSAC electrode, conducted in a 6 M KOH loaded symmetric supercapacitor, demonstrated an ultrahigh capacitance of 367 F g−1 at a current density of 0.2 A g−1 together with 92.09% retention after 10,000 cycles at 10 A g−1. More impressively, the zinc–ion hybrid supercapacitor using CSAC as a cathode achieves a high-rate capability (153 mAh g−1 at 0.2 A g−1 and 75 mAh g−1 at 10 A g−1), high energy density (134.9 Wh kg−1 at 175 W kg−1), as well as exceptional cycling stability (93.81% capacity retention after 10,000 cycles at 10 A g−1). Such work thus illuminates a new pathway for converting biowaste-derived carbons into materials for ultrahigh-performance energy storge applications.

“…Similarly, Wang et al. adopted durian kernel (DK) to synthesis N/O/S ternary‐doped hierarchical porous carbons (HPCs) by KOH activation [21b] . The product contained high heteroatoms content from itself, hierarchically porous structure, large specific surface area, and high electrical conductivity, contributing to the excellent electrochemical properties as electrode material for SCs and LIBs.…”

The environmental impact from the waste disposal has been widely concerned around the world. The conversion of wastes to useful resources is important for the sustainable society. As a typical family of wastes, biomass materials basically composed of collagen, protein and lignin, are considered as useful resources for recycle and reuse. In recent years, the development of carbon material derived from biomasses, such as plants, crops, animals and their application in electrochemical energy storage have attracted extensive attention. Through the selection of the appropriate biomass, the optimization of the activation method and the control of the pyrolysis temperatures, carbon materials with desired features, such as high‐specific surface area, variable porous framework, and controllable heteroatom‐doping have been fabricated. Herein, this review summarized the preparation methods, morphologies, heteroatoms doping in the plant/animal‐derived carbonaceous materials, and their application as electrode materials for secondary batteries and supercapacitors, and as electrode support for lithium‐sulfur batteries. The challenges and prospects for the controllable synthesis and large‐scale application of biomass‐derived carbonaceous materials have also been outlooked.

“…The obtained mixture was placed in a tube furnace in an Ar and activated at 800 °C for 2 h (5 °C min −1 ). [37][38][39] Aer the temperature dropped to room temperature, 1 mol L −1 HCl solution was added to the activated sample, stirred for 12 h to remove remaining KOH and by-products generated during the activation process, then washed with deionized water and ethanol until the solution became neutral, and nally dried at 110 °C to obtain activated brous brucite template carbon (AHTFBC 2 ) (Fig. 2).…”
