“…[13][14][15][16] The general strategy for the production ofall-gel-state supercapacitors is based on the chemical modification of hydrogels with additives to reach desirable electrical conductivity to electrodes and ionic conductivity to solid electrolytes. 17 In addition, the gel-based electrolyte is preferred for use as separators because of the characteristic cold-tolerant properties, the fast charge-carrier transport, better tolerance to volumetric expansion-contraction, 18 and self-healing, 19,20 which are desirable properties for use in wearables. 21 For this, several methods are considered such as the direct ink writing of electrodes on gel-electrolyte 15 that results in samples with minimal damage after repeated stretching, bending, and squeezing.…”

The development of supramolecular structures (conducting hydrogels) obtained from the charge–charge interaction of sodium dodecyl sulfate micelles and oppositely charged polypyrrole chains represents an important step to obtain self‐supported and flexible electrodes for supercapacitors. Herein, the energy density of polypyrrole hydrogel‐based supercapacitors is enhanced by the incorporation of graphene nanoplatelets that introduced the electrical double capacitance contribution to the overall response. The electrochemical performance of synthesized electrodes was optimized from the relative variation in the concentration of supramolecular arrangements (micelles of sodium dodecyl sulfate), pyrrole, and graphene nanoplatelets. As result, higher capacitive retention is observed for modified electrodes (with the incorporation of graphene) – in order of 90% after 1000 cycles of use, preserving the high conductivity and intrinsic mechanical properties (flexibility and stretchability) reaching an areal capacitance of 210.7 mFcm−2.

“…The gel electrolyte‐based SSC retained 73.7 % performance even after 10 cutting cycles and could perform at 68.3 % capacity at −20 °C. This was possible due to the self‐healing capability of the supramolecular system [151] . All‐in‐one SCs utilize flexible electrodes and electrolytes to be directly integrated into wearables.…”

As the world moves towards renewable and sustainable energy sources, the need for systems that can quickly and safely store this energy is also rising. Supercapacitors (SCs) are among the most promising alternatives to conventional lithium‐ion batteries. SCs are more stable, have higher‐power densities, and can be charged much faster. However, SCs have their issues, and three of the main drawbacks of current SCs are 1) lower energy densities, 2) high cost of production, and 3) safety concerns in wearable devices. In this review, we discuss recent progress made in supramolecule‐based SCs (SSCs). In supramolecular systems, molecules are held stable using non‐covalent‐type bonds. This allows for a flexible system in which the molecular interaction sites can easily break and reform at low energy, allowing for exposure of highly active sites and self‐healing. When heterometal atoms are introduced into these supramolecular systems, this allows for further activation of the metal sites through the metal‐metal interaction along with the metal‐ligand interactions. This review discusses different types of SSCs (carbon‐based and metal‐incorporated) that have been utilized in recent years depending on their synthesis process. The working principle of SSCs and the utilization of different supramolecular elements that enhance the performance of SCs have also been discussed.

“…The developed supercapacitor showed areal capacitance of 7.69 F/cm 2 at 0.5 mA/cm 2 with energy density of 0.53 mWh/cm 2 . The developed supercapacitor showed similar performance damage and self‐healing after 6 h. Qin et al (2020) reported the fabrication of supramolecular gel polymer electrolyte by crosslinking PVA with tannic acid along with polyaniline deposited carbon cloth electrode and polyaniline as a current collector. The developed assembly showed a specific capacitance of 88.35 F/g and capacitance retention of 97% after 3000 charge–discharge cycles.…”

Current collectors play a very crucial role in the performance of an energy storage device. Regarding supercapacitors, material design, processing, and current collectors' surface properties can result in substantial variation in energy density, power output, cyclic charge–discharge behavior, and other key performance parameters. Most of the reviews in supercapacitor materials and devices focus on the synthesis, characterization, and electrochemical properties of electrode materials. In the present report, the recent advances in supercapacitor electrodes in conjunction with current collector materials and design are summarized in light of various supercapacitor devices categorized concerning their applications and working mechanisms. It includes the literature documented on multifarious supercapacitors, that is, flow supercapacitors, alternating current line filtering supercapacitors, redox electrolyte‐enhanced supercapacitor, metal ion hybrid supercapacitors, microsupercapacitors, electrochromic supercapacitors, and self‐healing supercapacitors. To the best of authors' knowledge, this is a new and recent summarized report on the development of current collector materials based on intended applications and the working principles of supercapacitors.
