“…The CV curves of α‐MnO 2 and GQD/PANI@MnO 2 nanofiber were characterized and compared as shown in Figure 4. The CV loops occurred in quasi‐rectangular shape and showed symmetric behavior, indicating the ideal capacitive behavior of the electrode material 24 . Also, there was a pair of weak cathodic and anodic peaks, demonstrating pseudocapacitive response due to the presence of pure PANI and α‐MnO 2 in the nanocomposite 25 …”

A new class α-MnO 2 nanofiber-based on assemblies of nanoparticles was synthesized to improve the availability of Mn atom for application in electrochemical storage. Furthermore, the effect of graphene quantum dots/polyaniline (GQD/PANI) on the structure and electrochemical performance of α-MnO 2 nanofiber was investigated. The MnO 2 nanofiber combined with GQD/PANI showed a larger specific capacitance of 1022.5 F g −1 at 1.0 A g −1 comparing to other MnO 2-based electrode materials. The result was attributed to α-MnO 2 nanofiber with loosely assembled structure and GQD/PANI with good conductivity, providing more electrochemical active sites and reducing internal resistance. The working does not only report new MnO 2-based electrode materials with high performance but also provides a facile method to synthesize α-MnO 2 nanofiber with a loosely assembled structure for various applications.

“…The gelation mechanism, [165] type and content of monomers in the precursor, [33] and degree of cross-linking, [6a] as well as content, type, and density of additives used in the structure of polymer hydrogels and porous composite structures based on these hydrogels can affect the energy storage performance of the final devices. [166] Moreover, easy carrier transport (electron and phonon) in the backbone of porous structures based on polymer hydrogels plays an important role in the energy storage properties of devices prepared from these materials. [167] The inherent ionic conductivity in the structure of conductive polymeric hydrogels due to electrolyte molecules trapped in the porous structure of these materials can improve the electrochemical performance of batteries and supercapacitors based on these hydrogels.…”

The recent and fast‐growing trends related to the development of wearable technologies have raised the need for efficient and high‐performance energy storage devices having extra features such as flexibility and lightweight. Polymer hydrogels, as viscoelastic lightweight porous nanostructures with tunable surface and structural properties, can play a crucial role in the design of these future energy storage devices. Herein, recent developments and progress in the use of polymer hydrogels to design flexible and wearable energy storage devices are presented and discussed. The 3D structure of polymer hydrogels and porous nanostructures based on these hydrogels provides a platform to design flexible supercapacitors, batteries, and personal thermal management devices. Herein, different types of polymer hydrogels are presented, and their main fabrication techniques are reported. Moreover, the main structural properties affecting the energy storage performance of polymer hydrogels are discussed. In addition to recent progress in the design of polymer‐hydrogel‐based wearable devices, recent developments in polymer hydrogels for flexible applications (batteries, supercapacitors, and thermal energy storage systems) are reviewed in detail.
