The enormous demand for energy due to rapid technological developments pushes mankind the limits in exploration of high-performance devices. Among two major storage devices (capacitors and batteries), electrochemical capacitors (known as ‘Supercapacitors’) play a crucial role supply conserved from various sustainable sources. high power density ultra-high cyclic stability are attractive characteristics supercapacitors. However, low is downside them, which also responsible extensive research this field help charge capabilities thrive their limits. Discoveries electrical double-layer formation, pseudocapacitive intercalation-type (battery-type) behaviors drastically improved performances introduction nanostructured active materials (carbon-/metal-/redox-active-polymer/metal-organic/covalent-organic framework-based electrode materials), electrolytes (conventional aqueous unconventional systems) with superior unprecedented device architectures further boosted characteristics. In addition, detailed investigations processes at electrode–electrolyte interfaces enable us reinforce present techniques approaches toward next-generation review, fundamental concepts supercapacitor terms components, assembly, evaluation, mechanism, advanced properties comprehensively discussed representative examples.

Conductive hydrogel strain sensors have triggered extensive research interest in artificial intelligence, human motion detection, electronic skin, and other technical fields. However, it is still challenging work to prepare conductive hydrogels integrated with good biocompatibility, recyclability, self-healing, strong adhesion properties both air underwater. Herein, a novel, ultraexcellent adhesive, multifunctional gelatin composite was fabricated through simple rapid one-pot method which (Gel) polyvinyl alcohol (PVA) were used as the polymeric skeletons, Tara tannin cross-linking agent, multiwalled carbon nanotubes (CNTs) conducting medium. Inspired by vegetable tanning mechanism chemistry, multiple hydrogen bonding hydrophobic interactions of Gel build network hydrogel. The obtained GTPC (Gel-Tara tannin-PVA-CNTs) exhibited considerable stretchability (760%), strength (16 kPa pigskin), high sensitivity (gauge factor (GF) = 6.79). In particular, displayed repeatable (≥10 times) self-healing performance (HE (self-healing efficiency) > 99%) formed sensor could accurately detect various signals, such finger bending, ankle smiling, also sensitively capture sensing signals body movements self-healed similar ability original one. This affords new idea for design fabrication flexible underwater performance, sensitivity, (in water) using tannin, promoting application diversified utilization tannin.
