“…The pores present in three dimensions enables them to provide good electrochemical properties to the electrode material. The appearance of a sponge‐like morphology consisting of nanofiber clumps was also confirmed in aromatic biomass‐based activated carbon from lemongrass leaves 42 . Abundant mesopores allow carbonaceous materials to have a barrier‐free charge transfer pathway thereby maintaining their high strength.…”

BACKGROUND: Biomass-based porous carbon as the basic component of electrodes has received wide interest as a renewable energy storage device with high chemical-physical stability and environmental friendliness. Therefore, novel biomass waste based on Zingiber officinale Rosc./red ginger leaves was synthesized as an electrode-based carbon material with an abundance of unique macaroni-sponge-like hierarchical pore structure, as well as good chemical, physical and economic performance. Template/metal-organic framework-free red ginger leaf-based hierarchical porous carbon (RGPC) was prepared using a facile and zero-residue technique as electrode material for supercapacitor application. RESULTS: Additionally, ZnCl 2 impregnation with concentrations of 0.1, 0.3 and 0.5 mol L −1 was utilized for increasing the active sites between electrode and electrolyte ions through interconnecting microchannels. The combination of macaroni-spongelike structure, amorphous nature, optimum specific surface area and availability of oxygen functional groups as a self-doping heteroatom of RGPC-0.3 greatly optimized the electrochemical performance of symmetric supercapacitor cells. The RGPC-0.3 electrode had an ideal specific capacitance of 215.76 F g −1 with a specific energy of 29.966 Wh kg −1 and maximum specific power of 108 W kg −1 at 1 mV s −1 in a symmetric supercapacitor system. Furthermore, a relatively good coulombic efficiency of 71.01% was obtained with a low equivalent series resistance of 0.098 Ω. CONCLUSIONS:This study provides insight into the generation of unique hierarchical porous carbon as a basic component of electrodes for energy storage applications with high electrochemical performance through the utilization of waste red ginger biomass with a simple, facile and cost-effective strategy.

“…The vaporization of elements, aside from carbon, bound to the carbon chain generates voids referred to as pores. Thus, a carbon material exhibiting a greater reduction in density implies a higher decomposition of non-carbon elements [43]. This occurrence signifies the extensive formation of pores in an activated carbon material with a heightened degree of carbon purity.…”

Carbon material sourced from bio-organic waste is a promising electrode material exploration for the development of sustainable supercapacitor devices. Interestingly, their relatively environmentally benign sources and unlimited availability are the right choices to be developed as energy conversion systems and energy storage applications. Here, a novel high-potential bio-waste has been studied as a carbon source for electrode materials for symmetrical supercapacitor applications. Biomass materials were selected from Cinnamomum Verum leaves waste which was given a series of measurable and systematically structured treatments. Carbon precursor was synthesized with a simple strategy through a one/two-step activation ratio in an integrated pyrolysis system. Their chemical impregnation focused on H3PO4, ZnCl2, and H3PO4+ZnCl2 solutions. The renewal of the study was also highlighted in the design of a solid coin-like carbon cylinder material without additive binder. The solid carbon material that has been obtained has been evaluated for all dimensions including mass, thickness, diameter, and volume. In addition, the density of the coins that have been generated through density calculations is also reviewed. The density of the coin’s carbon shows a value of 0.98 g cm−3 with an average standard deviation of 0.08. The electrochemical properties of carbon electrode materials were studied through cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) analysis. In the two-system configuration, the optimized electrode exhibits a specific capacitance of 162.83 F g−1 at 1 A g−1 and 101 F g−1 at 10 A g−1. Furthermore, their performance is relatively high at a coulombic efficiency of around 76.23% with a capability rate of 63.11%. Moreover, the resulting energy density is 17.18 Wh kg−1 at a maximum power density of 125 W kg−1. Therefore, this study offers a new strategy to obtain carbon solid coin-like from bio-organic sources of Cinnamon Verum leaves as a high-quality electrode material to improve the performance of symmetric energy storage devices.

The aim of this research is to formulate activated carbon monolith from hazardous waste of cigarette filter butts (CFB) for electrode material monolith design in solid-state supercapacitor application. Potassium hydroxide (KOH) was selected for activation. The ratio of CFB to KOH varied in terms of weight between 1:2 and 1:4, thereby obtaining activated cigarette filter carbon (ACFC). The carbon that has been obtained is designed to be solidly in the form of an additive-free monolith. Monolith-activated carbon is physically characterized to examine thermal decomposition profiles (pre-carbonized), structure, composition, morphology, surface area adsorption, and electrochemical measurements. The optimum precursor was marked with high wettability with self-O-doped of 5.44%.in carbon content of 94.56%. Activated carbon electrodes prepared from ACFCs showed an optimum specific capacitance of ~87.17 F g-1, which is a more ecologically responsible method of producing supercapacitors.
