“…Figure a shows the galvanostatic charge‐discharge (GCD) curves of DC‐GPE and LiClO 4 solution recorded from 0 to 1.5 V at different current densities of 0.5–5 A g −1 . The linear, symmetrical GCD curves indicates that there was reversible capacitive behavior and no pseudocapacitive behavior in the carbon electrodes . In GCD measurements, the decrease of potential (IR drop) in the initial stage of discharge is caused by the R b inside the capacitor.…”

Excellent mechanical properties are indispensable for the wide application of supercapacitors and various wearable devices. In this article, a novel double‐crosslinked hydrogel electrolyte (DC‐GPE) is prepared by the combination of the hydrophobic association of acrylamide with the amphiphilic monomer AEO‐9‐AC and the ionic complexation of acrylic acid with Fe3+ for the first time by a two‐step method. Owing to the dual energy dissipation network, the DC‐GPE exhibits an excellent tensile strength of up to 3.1 MPa, an elongation at break of more than 900 % and a toughness of 18.1 MJ m−3, which is far beyond the currently reported hydrogel electrolyte. Moreover, the ionic conductivity of the DC‐GPE achieves as high as 40.1 mS cm−1, which is 3 times higher than the corresponding LiClO4 solution electrolyte (12.3 mS cm−1). Besides, the activated carbon‐based supercapacitor assembled by the DC‐GPE shows excellent electrochemical performance, which is superior to most activated carbon‐based supercapacitors. These results demonstrate that the DC‐GPE shows a great application prospect in wearable devices like supercapacitors. Significantly, the new dual physical cross‐linking strategy improves the contradiction between the strength and the toughness of the gel electrolyte materials. And provides a new solution for preparing high‐strength as well as high‐toughness gel electrolyte.

“…Recently, lithiated sulfonyl PEKs gained attention because the ionomers act as an efficient electrode binder which enhances the ionic conductivity and lithium diffusion upon high rate cycling processes [42,43]. Nan Lu et al employed the lithiated sulfonyl copolymerized PEK (P7 in figure 2) as a nanofiber matrix with initial T 5% over 300 °C and high mechanical stability, and further improved voltage stability maintain from 0 to 2.0 V [39]. Furthermore, another ether modified PEK was proposed by Zhen Li et al [44].…”

Poly(arylene ether)s (PAEs) engineering plastics are a type of high-performance material which are excellent in thermal resistance, mechanical properties, and have low dielectric constant and anti-corrosion. Over recent decades, PAEs further combined with the electrospinning technology to fabricate as large surface-to-volume ratio and porosity membrane materials for high-performance applications. In this review, progresses of PAEs-based electrospun nanofibers and fiber reinforced composites including proton/anion exchange membranes, oil-water separation membranes, bio-scaffolds and humidity sensors, etc. are presented together with their corresponding high-performance applications in the fields of fuel cell, wastewater treatment, bioengineering and flexible durable sensor. Finally, current challenges and future development directions of PAEs electrospun nanofibers are discussed.

The frequency dependent AC conductivity and dielectric studies of multiferroic filler (Bi 1-x Ba x FeO 3 ) doped nanocomposite gel polymer electrolyte (NCGPEs) based on PVA:(NH 4 CH 3 COO) are investigated in the present work. The nano composite gel polymer electrolyte systems are synthesized for various filler concentrations by solution cast method. The effect of filler concentration on ionic conductivity is studied using AC impedance technique in the frequency range 1-10 6 Hz. X-ray diffraction studies reveal the formation of nanocomposite gel polymer electrolyte. The low frequency dispersion in the dielectric response of electrolytes shows the relaxation contribution is superimposed with electrode polarization effects. The relaxation peaks in the NCGPEs are found to shift toward higher frequency side with increasing filler concentration and are suitably correlated to change in morphology of the gel electrolyte system. The variation of AC conductivity with frequency is seen to obey Jonscher's universal power law with the exception of small deviation in the low frequency regime. Modulus formalism of dielectric response suggests that the ion transport is strongly coupled to the polymer segmental motion.
