Flexible electronics have gained much interest, amplifying the need for advanced compact, lightweight, and bendable power sources. Present flexible supercapacitive energy-storage devices are restricted by poor mechanical properties, low cyclic stability, and small capacitance. Here, with state-of-the-art technology, cerium selenide nanopebbles are assembled with the aid of a controlled diffusive–capacitive mutualistic approach via a simple chemical method on multiwalled carbon nanotubes (MWCNTs) surfaces to design a hybrid nanostructure. The synthesized material has been well-characterized through structural, surface morphological, and elemental states by X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). Benefiting from diffusive–capacitive control, the unique hybrid supercapacitor (SC) electrode delivered an excellent storage capability of 451.4 F/g (@2 mA/cm2) maintaining 70.7% (@4000 cyclic voltammetry (CV) cycles) capacitance retention. More prominently, supreme mechanical bending of the designed solid-state supercapacitor in the symmetric configuration with the help of a poly(vinyl alcohol) (PVA)-LiClO4 gel electrolyte yields 86.9% retention at a bending angle of 175° with improved performance compared to a liquid-configured (84.1%@4000 cycles) supercapacitor maintaining a remarkable capacitance of 128.8 F/g (@2 mV/s) with high power density (2.8–5.6 kW/kg at energy densities of 36.3–14.5 Wh/kg).

“…Among 0, 5, 10, and 15 wt % esHPMs, 10 wt % esHPM has the minimal melting temperature of 158.41 °C. Crystallinity values have been obtained using latent heat of crystallization, following the earlier reported procedure. , Among the esHPMs, the 10 wt % esHPM exhibits reduced crystallinity compared to the esPM. No major deviation in crystallinity values has been observed due to incorporation of highly crystalline active fillers, contributing significantly to the thermal transitions. ,, …”

“…PVDF and its copolymer poly(vinylidene fluoride- co -hexafluoropropylene) (PVDF-HFP) have drawn significant interest as a polymer electrolyte for batteries and supercapacitor applications. Due to the advantages such as semi-crystalline nature, high polarity, high dielectric constant, wide electrochemical stability window, appreciable adhesion capability with the electrodes, and presence of an electron-withdrawing solid group (−C–F−), PVDF-HFP is highly preferred over polymer electrolytes like PAN, PMMA, PEO, and PVC, and so forth. − PVDF-HFP is a semi-crystalline polymer having four polymorphs identified as α, β, γ, and δ . The α-phase is the signature of non-polar crystalline nature, while the β-phase is polar and signifies the crystalline nature of the material.…”

A novel solid-state electrospun nanohybrid polymer membrane electrolyte (esHPME) for sodium-ion capacitors to improve the ionic conductivity and energy density is demonstrated. A Na2Zn2TeO6 (NZTO)-embedded 3D-nanofibrous poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) nanohybrid electrolyte has been reported as a high-sodium-ion conducting electrolyte for sodium-ion capacitor applications. PVDF-HFP based esHPMEs with different loadings (0, 5, 10, and 15 wt %) of NZTO nanoparticles are prepared by electrospinning and further activated by soaking them in a liquid electrolyte (1M of NaPF6 in EC/DMC, 1:1 v/v) to employ as the electrolyte-separator. Among the prepared esHPMEs, the 10 wt % NZTO-embedded esHPME exhibits the maximum ionic conductivity and electrochemical window of 2.5 V. The influence of hybridization between inorganic nanoparticles (NZTO) and the organic polymer (PVDF-HFP) is investigated by physical characterization and their electrochemical performance. A coin cell-type Na-ion supercapacitor is fabricated using battery-type Na0.67Co0.7Al0.3O2 as the anode and activated carbon as the cathode. The fabricated Na-ion supercapacitor [Na0.67Co0.7Al0.3O2/esHPME (10 wt % NZTO)/AC] delivered an energy density of 99.375 F g–1 at 1 A g–1 current density and exhibits 84% of capacity retention up to 1000 cycles of charge discharging. The Na-ion capacitor showed a maximum energy density and power density of 35.33 W h kg–1 and 1.6 kW kg–1, respectively. Thus, the present work demonstrates the great potential of the electrospun PVDF-HFP/NZTO-based nanohybrid membrane electrolyte for durable Na-ion capacitors.

“…Similar to the passive fillers, the as‐prepared Li + conductive ceramics can be directly added into the polymer solution, through which the composite nanofibers are fabricated in one‐pot via the electrospinning technique. Regarding that nanoparticles act as the active fillers, various ceramics such as Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 , 179 Li 7.1 La 3 Ba 0.05 Zr 1.95 O 12 , 180 Li 7.1 La 3 Sr 0.05 Zr 1.95 O 12 , 181 Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 , 182 Li 6.28 Al 0.24 La 3 Zr 2 O 12 183 have been reported to be incorporated into the polymer nanofibers via the electrospinning technique. As a typical example (Figure 14A), Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 nanoparticles were mixed with PAN with different mass ratios in the presence of N,N‐dimethylformamide, which were then subjected to the electrospinning procedure to prepare the Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 nanoparticles incorporated PAN nanofibers composite (LATP/PAN).…”

Solid‐state electrolytes (SSEs), being the key component of solid‐state lithium batteries, have a significant impact on battery performance. Rational materials structure and composition engineering on SSEs are promising to improve their Li+ conductivity, interfacial contact, and mechanical integrity. Among the fabrication approaches, the electrospinning technique has attracted tremendous attention due to its own merits in constructing a three‐dimensional framework of SSEs with precise porosity structure, tunable materials composition, easy operation, and superior physicochemical properties. To this end, in this review, we provide a comprehensive summary of the recent development of electrospinning techniques for high‐performance SSEs. Firstly, we introduce the historical development of SSEs and summarize the fundamentals, including the Li+ transport mechanism and materials selection principle. Then, the versatility of electrospinning technologies in the construction of the three main types of SSEs and stabilization of lithium metal anodes is comprehensively discussed. Finally, a perspective on future research directions based on previous work is highlighted for developing high‐performance solid‐state lithium batteries based on electrospinning techniques.
