“…As the typical representative, supercapacitors (SCs) have widely aroused scientific and technological interests due to their high-power output, fast charge-discharge kinetics, and long cycle life [8][9][10]. These advantages make them become the favorable candidates for applications of portable electronic device or hybrid electric vehicles [11,12]. Nonetheless, inferior energy density of SCs has hindered their extensive application in the near future.…”

HIGHLIGHTS • The ultrathin nickel metal-organic framework (MOF) nanosheets in situ interpenetrated by functional carboxylated carbon nanotubes (C-CNTs) were successfully constructed. The incorporated C-CNTs effectively adjust the layer thickness of Ni-MOF nanosheets. • The integrated hybrid MOF nanosheets delivered the boosted electrochemical performances and exhibited superior specific capacity of 680 C g −1 at 1 A g −1 .

Conducting polymers integrated with metal oxides create opportunities for hybrid capacitive electrodes. In this work, we report a one-pot oxidative polymerization for the synthesis of integrated conductive polyindole/nickel oxide (PIn/NiO), polyindole/zinc oxide (PIn/ZnO), and polyindole/nickel oxide/zinc oxide (PNZ). The polymers were analyzed thoroughly for their composition and physical as well as chemical properties by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis), and thermogravimetric analysis (TGA). The PIn and its composites were processed into electrodes, and their use in symmetrical supercapacitors in two- and three-electrode setups was evaluated by cyclic voltammetry (CV), galvanostatic discharge (GCD), and electrochemical impedance spectroscopy (EIS). The best electrochemical charge storage capability was found for the ternary PNZ composite. The high performance directly correlates with its uniformly shaped nanofibrous structure and high crystallinity. For instance, the symmetrical supercapacitor fabricated with PNZ hybrid electrodes shows a high specific capacitance of 310.9 F g−1 at 0.5 A g−1 with an energy density of 42.1 Wh kg−1, a power density of 13.2 kW kg−1, and a good cycling stability of 78.5% after 5000 cycles. This report presents new electrode materials for advanced supercapacitor technology based on these results.

“…SEM results and the digital photographs also confirmed that PAM penetrated the porous structure of the cellulose network ( Figure 2 b,c). The prepared CN/PAM composite was employed as an anode, and the in situ deposition of PANI was conducted through the electrochemical oxidation polymerization of aniline [ 19 ]. A large amount of green PANI was deposited on the cross section of the CPP composite hydrogel ( Figure 2 d).…”

With the continuous development of energy storage devices towards sustainability and versatility, the development of biomass-based multi-functional energy storage devices has become one of the important directions. In this study, a symmetric dual-function supercapacitor was constructed based on a cellulose network/polyacrylamide/polyaniline (CPP) composite hydrogel. The presented supercapacitor, with excellent electrochemical performance and an areal capacitance of 1.73 mF/cm2 at 5 mV/s, an energy density of 0.62 µW h/cm2 at a power density of 7.03 µW/cm2, a wide electrochemical window of 1.6 V and a promising cycling stability, can be achieved. The transmittance of the supercapacitor at 500 nm decreased by 9.6% after the electrification at 3 V, and the device can exhibit periodic transmittance change under the square potential input between 0.0 V and 3.0 V at regular intervals of 10 s. The present construction strategy provides a basis for the preparation of multifunctional devices with natural renewable materials and structures.
