“…In order to solve these problems, we present a strategy to develop PAni@rGO electrodes for high-performance supercapacitors via the preparation of ternary composite. Hence, the porous AC was prepared from olive stones (OS) through a process known as carbonization [30,31]; it was subsequently used to cover rGO sheets via a simple method. Then, the OS−rGO was coated with a polymer matrix using chemical polymerization of an Ani monomer.…”

Graphene-based materials have been widely studied in the field of supercapacitors. However, their electrochemical properties and applications are still restricted by the susceptibility of graphene-based materials to curling and agglomeration during production. This study introduces a facile method for synthesizing reduced graphene oxide (rGO) nanosheets and activated carbon based on olive stones (OS) with polyaniline (PAni) surface decoration for the development of supercapacitors. Several advanced techniques were used to examine the structural properties of the samples. The obtained PAni@OS−rGO (1:1) electrode exhibits a high electrochemical capacity of 582.6 F·g−1 at a current density of 0.1 A·g−1, and an energy density of 26.82 Wh·kg−1; thus, it demonstrates potential for efficacious energy storage. In addition, this electrode material exhibits remarkable cycling stability, retaining over 90.07% capacitance loss after 3000 cycles, indicating a promising long cycle life. Overall, this research highlights the potential of biomass-derived OS in the presence of PAni and rGO to advance the development of high-performance supercapacitors.

“…So far, various precursors have been applied in the preparation of porous carbon materials, such as polyacrylonitrile, phenolic resins, polyaniline, biomass, and related derivatives [31][32][33][34][35]. Among them, polybenzoxazines (PBZs) are a kind of newly developed phenolic resins based on heterocyclic compounds with good molecular design flexibility.…”

Heteroatom-doped porous carbon materials are highly desired for supercapacitors. Herein, we report the preparation of such material from polybenzoxazine (PBZ), a kind of phenolic resin. Four different N- and O-codoped microporous carbon materials were obtained by changing carbonization temperature (600, 700, 800, and 900 °C). Their structures were characterized by scanning electron microscopy (SEM), nitrogen isothermal absorption and desorption, X-ray diffraction (XRD), Raman spectroscopy, elemental analysis and X-ray photoelectron spectroscopy (XPS), and their electrochemical performances were evaluated by cyclovoltammetry (CV) and galvanostatic charge–discharge (GCD) test in a three-electrode system. It was found that the carbon material (C-700) prepared at the carbonization temperature of 700 °C possesses the largest specific surface area (SSA), total pore volume and average pore size among the family, and thus displays the highest specific capacitance with a value of 205 F g−1 at a current density of 0.25 A g−1 and good cycling stability. The work demonstrates that the N- and O-codoped microporous carbon materials with high electrochemical performance can be derived from benzoxazine polymers and are promising for supercapacitor application.

“…[10][11][12] Carbon-based materials with electric double-layer capacitance behavior, such as activated carbon, have a rich pore structure, large specific surface, and good cycle stability. [13][14][15] They have the conditions for the preparation of excellent electrode materials and have attracted attention. However, traditional activated carbon is produced from coal and its derivatives, which is non-renewable and its high cost limits its development.…”

Kochia that is used as Chinese herbal medicine is always abandoned as a biowaste after extracting useful components. However, the richness of lignocellulose and the natural tubular structure make it a potential source of biomass carbon. After high‐temperature pyrolysis at 800 °C and further etching by proper activation conditions, a graded porous structured carbon‐based supercapacitor electrode material (KAC‐5) can be obtained. The electrode material is prepared in a 1:5 carbon‐to‐base ratio, possessing a specific surface area of 1441.30 m2 g−1, and a graded macro‐meso‐micro structure that is rich in micropores. The capacitance retention retains at 90.31% even after 10 000 cycles in 6 m KOH electrolyte and exhibits outstanding capacitance performance with a specific capacitance of 284 F g−1 at a current density of 1 A g−1. The symmetrical supercapacitor is assembled with KAC‐5 and also has good cycling stability in 6 m KOH aqueous electrolyte, reaching 88.83% after 10 000 cycles with an energy density of 12.3 Wh kg−1 at a power density of 300 W kg−1. Based on the above, sustainable preparation of energy storage material from waste biomass for high capacitance and stable biomass‐based supercapacitors has been achieved.
