“…Hierarchical porous activated carbon (HPAC) with very high specific surface area (normally more than 1000 m 2 /g) is known for its outstanding energy storage performances as the active electrode materials in SCs that store electricity via the electrochemical double layer [ 5 , 6 , 7 , 8 ]. The energy storage capabilities of HPAC are primarily determined by the physical features, especially the porous structure.…”

“…Specifically, the macropores (>50 nm) serve as the ion-buffering reservoirs, mesopores (2–50 nm) serve as the electrolyte ions transport channels, and micropores (<2 nm) usually serve as the charge storage sites [ 9 , 10 , 11 ]. Recently, various efforts have been made to synthesize the HPAC [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Given by such distinctive contributions of HPAC, their electrochemical performances including specific capacitance, rate capabilities, cycle stability, etc.…”

Rational design and development of the electrodes with high-mass loading yet maintaining the excellent electrochemical properties are significant for a variety of electrochemical energy storage applications. In comparison with the slurry-casted electrode, herein, a hierarchically porous activated carbon (HPAC) electrode with higher mass loading (8.3 ± 0.2 mg/cm2) is successfully prepared. The pouch-type symmetric device (1 cell) with the propylene carbonate-based electrolyte shows the rate capability (7.1 F at 1 mA/cm2 and 4.8 F at 10 mA/cm2) and the cycling stability (83% at 12,000 cycles). On the other hand, an initial discharge capacitance of 32.4 F and the capacitance retention of 96% after 30,000 cycles are delivered from a pouch-type symmetric supercapacitor (five cells). The corresponding electrochemical performances are attributed to the fascinating properties of the HPAC and the synergistic features of the resulting electrode.

“…Due to the sluggish reaction kinetics of metal oxides, the major electrode materials, pseudocapacitors have poor cycle stability compared to EDLCs. EDLCs exhibit the high power density, rapid charge–discharge cycle, long cycling life, and safety [ 2 ]. However, the low energy density of EDLCs has severely limited its practical applications.…”

“…This results in small specific surface area and poor pore structure, leading to its poor conductivity and high contact resistance between the activated carbons and the electrolyte, which is not beneficial for energy storage applications. It has been reported that porous carbon-based materials with high specific surface area, suitable pore structure, and favorable functional groups have the promising applications as the electrode materials for EDLCs and hybrid supercapacitors [ 2 , 4 ]. Besides, the materials’ cost and environmental impacts during the material preparation are vital to the large-scale commercial popularization of supercapacitors.…”

A series of heteroatom-containing porous carbons with high surface area and hierarchical porosity were successfully prepared by hydrothermal, chemical activation, and carbonization processes from soybean residues. The initial concentration of soybean residues has a significant impact on the textural and surface functional properties of the obtained biomass-derived porous carbons (BDPCs). SRAC5 sample with a BET surface area of 1945 m2 g−1 and a wide micro/mesopore size distribution, nitrogen content of 3.8 at %, and oxygen content of 15.8 at % presents the best electrochemical performance, reaching 489 F g−1 at 1 A g−1 in 6 M LiNO3 aqueous solution. A solid-state symmetric supercapacitor (SSC) device delivers a specific capacitance of 123 F g−1 at 1 A g−1 and a high energy density of 68.2 Wh kg−1 at a power density of 1 kW kg−1 with a wide voltage window of 2.0 V and maintains good cycling stability of 89.9% capacitance retention at 2A g−1 (over 5000 cycles). The outstanding electrochemical performances are ascribed to the synergistic effects of the high specific surface area, appropriate pore distribution, favorable heteroatom functional groups, and suitable electrolyte, which facilitates electrical double-layer and pseudocapacitive mechanisms for power and energy storage, respectively.

“…In recent years, biomass-derived carbon materials have been widely studied due to their structural diversity and attractive properties, which may be tailored by various preparation procedures and activation methods [ 1 , 2 , 3 , 4 , 5 , 6 ]. Porous carbonaceous materials including activated carbons (AC) due to their chemical stability, superior electrical conductivity, high specific surface area, large pore volume and specific pore structure are used in many application: photochemical degradation [ 7 , 8 ], catalyst carrier, adsorption [ 9 , 10 ], carrier of a phase change materials (PCMs) for application in building materials [ 11 ], fuel cells [ 12 ], energy conversion and storage [ 13 , 14 , 15 ]. A popular research direction is to reuse biomass as an environmentally friendly, easily accessible, low-cost and renewable carbon precursor.…”

Chestnut-Derived Activated Carbon as a Prospective Material for Energy Storage

et al. 2020

View full text Add to dashboard Cite

In this work, we present the preparation and characterization of biomass-derived activated carbon (AC) in view of its application as electrode material for electrochemical capacitors. Porous carbons are prepared by pyrolysis of chestnut seeds and subsequent activation of the obtained biochar. We investigate here two activation methods, namely, physical by CO2 and chemical using KOH. Morphology, structure and specific surface area (SSA) of synthesized activated carbons are investigated by Brunauer-Emmett-Teller (BET) technique and scanning electron microscopy (SEM). Electrochemical studies show a clear dependence between the activation method (influencing porosity and SSA of AC) and electric capacitance values as well as rate capability of investigated electrodes. It is shown that well-developed porosity and high surface area, achieved by the chemical activation process, result in outstanding electrochemical performance of the chestnut-derived porous carbons.
