“…The use of a variety of nano-and/or composite materials as an electrode has made significant improvements in ion diffusion length and volumetric expansion issues during charge/discharge process [9][10][11][12][13][14][15]. Graphene, regarded as the most interesting material since Novoselov synthesized it in 2004 [16], is a two-dimensional structure made of a single layer of carbon atoms.…”

Carbon‐doped polyaniline (PANI) hydrogels (PFMH) are fabricated by a facile hydrothermal strategy that aniline monomers are in situ polymerized on mesoporous carbons (MC) and carbon fibers (CF) with phytic acids as both cross‐linkers and dopants. Likewise, MC and CF can provide heterogeneous active sites to initiate the polymerization, acting as the skeletons within multi‐dimensional interconnected channel structures. First‐principles density functional theory calculations show that the interactions between different bases of PANI and MC/CF are all adsorptive prone to possess the separation‐free structure, but the adsorptive interactions between different bases and MC are significantly stronger than those of CF. Therefore, MC would be tightly anchored by PANI chains to improve the mechanical strength, while CF can provide favorable conductivity interconnected network skeletons. As such, the electrical conductivity and fracture strength of PFMH are measured high up to 13.32 S m−1 and 233.4 kPa at the fracture deformation (54.7%), respectively. PFMH as supercapacitor (SC) electrodes can achieve the gravimetric specific capacitance of 637.9 F g−1 at 1 A g−1. In particular, the as‐fabricated flexible all‐solid‐state SCs can maintain normal operation under various deformation conditions, showing the great potential to become an advanced power device for wearable electronics.

“…Among these, wearable flexible supercapacitors have been regarded as the perfect candidate and advanced trend for the application of wearable energy‐storage systems because of their superior power density, rapid charge–discharge capability, safe operation, and long cycling life. Especially, fiber‐shaped flexible supercapacitors exhibit the outstanding flexibility, elasticity, good safety, prominent electrochemical performance, and potentials in integration into a cloth so that they have drawn remarkable attentions 10–12 …”

Carbon fibers (CFs) are a promising candidate as electrode materials for flexible supercapacitors given its light weight and moderate cost. In this study, the lignin used was partially separated from kraft bamboo pulping black liquor and the higher molecular weight fraction, unavoidably contains a small amount of silicon compounds, so named silicon‐contained lignin. Novel CFs were prepared using commercial polyacrylonitrile (PAN) and the lignin by electrospinning and further carbonization. Even in the presence of silicon compounds, the fibrous morphology of precursor fibers was significantly good, and the CFs with uniform fiber diameter and high specific surface area up to 182 m2/g were obtained with an increase in silicon‐contained lignin. The CFs fabricated from silicon‐contained lignin and commercial PAN had higher specific capacitance (22.20 mF/cm2 at 10 mA/cm2) and superb cycling stability (94.21%) than that from silicon‐free lignin or pure PAN separately.
