Herein, a reverse bias heterojunction NiCoS/NiCo-OH with mesopores as the positive electrode was constructed by interface engineering. During the process of charging, the application of a positive bias potential by the external circuit to the reverse bias heterojunction NiCoS/NiCo-OH enhances the accumulation of charges within the NiCoS nanosheets. Under the modulation of the built-in electric field at the interface, the mesoporous interface of NiCo-OH acts as a receiver, collecting charges from NiCoS nanosheets and forming a channel leading to efficient ion diffusion and charge transfer. The specific capacity of the NiCoS/NiCo-OH electrode is up to 406.5 mA h g −1 at 1 A g −1 . It demonstrates ultrahigh rate performance, reaching 81.9% (50 A g −1 ) and 77.4% (100 A g −1 ). The hybrid supercapacitor NiCoS/ NiCo-OH//FNG shows a high energy density of 51.3 W h kg −1 at 1650 W kg −1 . Moreover, the capacity of the Zn||NiCoS/NiCo-OH battery reaches 419.1 mA h g −1 cathode at 1 A g −1 , and it can still maintain 73% (306.3 mA h g −1 cathode ) at 100 A g −1 .

“…Flexible and conformable energy storage devices such as flexible batteries and supercapacitors (SCs) could potentially be integrated with wearable systems to satisfy energy requirements. [16][17][18][19][20][21][22][23][24][25] Between the two, batteries offer reliable power output but suffer from low cycle life and declined power density. Due to its long cycle life, low charging time, and highpower densities, flexible SCs can be an ideal option for powering wearable e-textile devices.…”

With the advent of wearable electronics, the urge to devise new and flexible energy storage devices to power up wearable systems has steadily risen over the past few decades. Wearable fabric‐based supercapacitors have emerged as a fantastic solution for powering up these systems. Functionalizing fabric surfaces with electroactive materials has proven to be the ideal way to fabricate high‐performance wearable supercapacitors. In this review, the recent progress in functional fabric‐based wearable supercapacitors is summarized. The article begins with the introduction of different fabric structures and outlining the functional materials implemented in wearable supercapacitors. The emphasis shifts toward summarizing the fabrication of functional fabric‐based electrodes according to different fabric architectures. Then, different novel fabric‐based supercapacitor configurations, the current state of integration, and the durability of such devices are analyzed. The review is concluded by emphasizing the existing drawbacks, envisaging potential applications, and, most importantly, the future perspective of the technology.
