“…13,24 As a kind of natural resource, biomass has been considered as potential precursor for the preparation of carbon materials owing to its easily available, fast-renewable, low-cost and environmentally benign features. 26,[28][29][30] Consequently, carbon materials derived from biomass (including hemp, 8 cattle bone, 12 ginkgo leaves, 31 honeysuckle, 23 wheat stalk, 32 bamboo pulps, 33 peat moss, 34 and rice husk, 35 and cotton 36 ) by pyrolysis/ activation process as electrodes for SCs and LIBs have been explored. In addition, due to the variety of microstructures of natural biomass, the as prepared carbon materials can exhibit different structures, 37,38 which can offer favorable capacitance, high rate capability and long cycling life.…”

“…EDLCs store energy directly as the charge at the surface of electrode/electrolyte, while pseudocapacitors store energy based on faradic reaction, involving the transfer of charge across the interface between electrode and electrolyte. EDLCs' electrode materials take carbon material as the principal mechanism, mainly contain carbon nanotubes, 4 porous carbon, 5 N-doped carbon, 6,7 biomass carbon, [8][9][10][11][12] nanostructured carbon, [13][14][15][16] and graphene-based materials. 17 Pseudocapacitive electrode materials mainly include metal compounds, like Ni-based, 18 Mo-based, 19 Mn-based, [20][21][22] Co-based, [23][24][25][26][27][28][29] Ti-based, [30][31][32] and Vbased materials 30,[33][34][35][36][37][38][39][40][41] and conducting polymers, 42,43 like polyaniline, polypyrrole, and so on.…”

Nanocomposites of gold nanoparticles and polyaniline are synthesized by using HAuCl4 and ammonium peroxydisulfate as the co‐oxidant involving in situ polymerization of aniline and in situ reduction of HAuCl4. Through these in situ methods, the synthesized Au nanoparticles of ca. 20 nm embedded tightly and dispersed uniformly in polyaniline backbone. With the Au content in composite increasing from 4.20 to 24.72 wt.%, the specific capacitance of the materials first increased from 334 to 392 F g−1 and then decreased to 298 F g−1. Based on the real content of PANI in composite material, the highest specific capacitance is calculated to be 485 F g−1 at the Au amount of 19.15 wt.%, which remains 55.6% after 5000 cycles at the current density of 2 A g−1. Finally, the asymmetric supercapacitor of AuNP/PANI||AC and the symmetric supercapacitor of AuNP/PANI||AuNP/PANI are assembled. The asymmetric supercapacitor device shows a better electrochemical performance, which delivers the maximum energy density of 7.71 Wh kg−1 with power density of 125 W kg−1 and maximum power density of 2500 W kg−1 with the energy density of 5.35 Wh kg−1.

[15][16][17][18] Shaddock peels (approximately 10% of the total weight of shaddocks that are a popular fruit in China), as a carbon material derived from natural waste, are viewed as a high value-added precursor of biomass derived hard carbons and have been served as catalyst support, 19 adsorption, [20][21][22] capacitor, 23,24 and sodium-ion batteries (SIBs). 25 In the previous studies, 3D connected porous 25 and honeycomb-like 26 shaddock peel-derived hard carbons have been prepared, which showed excellent Na + storage properties.…”

Summary Sulfur doping has been regarded an energetic route to optimize the lithium storage properties of carbon‐based electrode materials. In this work, sulfur‐doped shaddock peel–derived hard carbon is successfully prepared by a KOH‐ and C2H5NS‐assisted pyrolysis procedure. It is demonstrated that sulfur doping has strong effect on surface activation and graphitization enhancement, which results in the significant enhancement of the surface adsorption capacity and reaction kinetics of the hard carbon materials. When employed as a lithium ion batteries (LIBs) anode, the as‐obtained hard carbon demonstrates excellent cycling and rate properties, presenting a great specific capacity of 738 mAhg−1 at 50 mAg−1 after 200 cycles, as well as 491 mAhg−1 at 200 mAg−1 after 300 cycles. Even at 1000 and 2000 mAg−1, the hard carbon provides a large rate capacity of 283 and 179 mAhg−1, respectively. Besides, it is revealed that the Li+ storage process is determined by the surface‐induced pseudocapacitive process, whose capacitive proportion reach 60% at 0.5 mVs−1. This work suggests that the low cost and eco‐friendly sulfur‐doped shaddock peel–derived hard carbon is a very prospective LIB anode material.
