“…[ 163 ] But the performance saw a significant drop when three metal oxides TiO 2 , ZnO, and MnO 2 took part in the paper electrode fabrication, that could be due to the weak interfacial between the TiO 2 and ZnO. [ 164 ] But the TiO 2 /PANI in the three‐electrode system exhibited a very high capacitance of 897.35 F g −1 at 0.21 A g −1 compared to the bare nanowires, because of the porous structure of the nanowires from the PANI, tube length of the Ti nanotube together provided the branches for continuous exchange of electrons persisting over 1500 cycles ( Figure ). [ 165 ] In the order of increasing the flexibility and allow the wearability with research in carbon/TiO 2 , the polyamide film was carbonized and laser is drawn with electrode pattern followed by electrophoresis and deposition of TiO 2 .…”

The progressive size reduction of electronic components is experiencing bottlenecks in shrinking charge storage devices like batteries and supercapacitors, limiting their development into wearable and flexible zero-pollution technologies. The inherent long cycle life, rapid charge-discharge patterns, and power density of supercapacitors rank them superior over other energy storage devices. In the modern market of zero-pollution energy devices, currently the lightweight formula and shape adaptability are trending to meet the current requirement of wearables. Carbon nanomaterials have the potential to meet this demand, as they are the core of active electrode materials for supercapacitors and texturally tailored to demonstrate flexible and stretchable properties. With this perspective, the latest progress in novel materials from conventional carbons to recently developed and emerging nanomaterials toward lightweight stretchable active compounds for flexi-wearable supercapacitors is presented. In addition, the limitations and challenges in realizing wearable energy storage systems and integrating the future of nanomaterials for efficient wearable technology are provided. Moreover, future perspectives on economically viable materials for wearables are also discussed, which could motivate researchers to pursue fabrication of cheap and efficient flexible nanomaterials for energy storage and pave the way for enabling a widerange of material-based applications.

“…Mixing these two classes of materials provides a nanocomposite material with collaboration and coping effects that create oxygen vacancies, which improves the ORR activity [19,20]. To enhance the electrochemical performance of the catalysts for ORR, nanocomposite catalysts such as CuO@MnO 2 [21], NiCo 2 O 4 @MnO 2 [22], TiO 2 @MnO 2 [23], ZnO/MnO 2 [24], Fe 2 O 3 -MnO 2 [25], Co 3 O 4 /MnO 2 -CNTs [26], and Co 3 O 4 @MnO 2 [27] have been investigated. The synergetic effect of the individual components allows the nanocomposite structure to exhibit improved characteristics [28].…”

“…In EDLCs, electrostatic adsorption takes place at the interface of the electrodes and electrolyte, whereas the redox reaction takes place in pseudocapacitors. [30][31][32][33][34][35] Due to some crucial evidence based on charge-storage phenomena, the electrode materials are classified as EDLCs and pseudocapacitor applications. The rectangular shape in cyclic voltammetry (CV) curves corresponds to non-Faradic reaction and charge storage takes place by adsorption on the interface of electrolyte and electrode surfaces.…”

Supercapacitors are very exclusive among energy‐storage devices for the wearable and portable industry. Due to simplicity, abundance occurrence, good electrical conductivity, and rich redox states, metal sulfides have a significant impact in supercapacitor applications in the present decade. Sulfur is the anion, associated with metal cations, and provides substantial tunable electrochemical, electrical, physical, and chemical properties in metal sulfides. In addition, carbonaceous materials enhance the electrochemical characteristics of metal sulfides synergistically for supercapacitors. Fast and scalable synthesis and fabrication of the supercapacitor cell with low‐cost metal sulfides and heterostructures should be developed to achieve the potential applications of these hybrid glorious materials. Herein, the significant and critical discussion of metal sulfides synthesis and their hybrid with carbon electrode structures for supercapacitor applications is disclosed. The realistic synthesis of metal sulfides, basic charge storage phenomena to elaborate the electrode nature, electrochemical properties including a single electrode, and asymmetric and symmetric cells are demonstrated for comparative purposes. The market values and application of supercapacitors are also elaborated. Herein, a better understanding to fresh readers about metal sulfide hybrid electrode structures for supercapacitors is provided.
