“…The CNT/Mn 3 O 4 based micro SCs using this gel electrolyte exhibited a 30 times higher energy density than that of graphene‐based micro SCs with PVA‐H 3 PO 4 gel electrolyte. Similarly, Tang et al presented a stretchable SC using Na 2 SO 4 –anionic polyurethane acrylates/polyacrylamide (aPUA/PAAM) hydrogel electrolyte with intrinsic stretchability over 1000% . The strong stickiness and high ionic conductivity of the hydrogel electrolyte result in good electrochemical performances of the SC under large strains, delivering a specific capacitance of 478.6 mF cm −2 at 0.5 mA cm −2 and 91.5% retention of its initial capacity after 3000 stretching cycles up to 150% strain .…”

wearable devices, [1,2] sensitive robotic skin, [3] electronic papers, [4] soft surgical tools, [5] electronic imaging devices, [5] in vivo health monitors, [3] as well as various collapsible gadgets [6] has attracted widespread attention upon flexible and stretchable electronics with a combination of advanced electrical performance with robust mechanical properties such as stretchability, foldability, twistability, flexibility, and durability. [7,8] In particular, device stretchability is highly desirable for wearable electronics due to the inevitable deformation (strain) generated in human skin and human body activity. As essential components of stretchable electronics systems, energy conversion and storage devices should be capable of sustaining their performance when subjected to the large strains that may be experienced by the highly stretchable electronics in various applications. The consistency of stretchability in both electronics and energy devices becomes the key to the successful integration of a combined self-powered stretchable system in wearable electronics applications. To date, significant effort and progress have been made in developing stretchable energy devices such as batteries, supercapacitors (SCs), and solar cells. [9][10][11][12][13] Although batteries are typically favored among power sources for electronic devices due to their superior power density and energy Supercapacitors (SCs) have shown great potential for mobile energy storage technology owing to their long-term durability, electrochemical stability, structural simplicity, as well as exceptional power density without much compromise in the energy density and cycle life parameters. As a result, stretchable SC devices have been incorporated in a variety of emerging electronics applications ranging from wearable electronic textiles to microrobots to integrated energy systems. In this review, the recent progress and achievements in the field of stretchable SCs enabled by low-dimensional nanomaterials such as polypyrrole, carbon nanotubes, and graphene are presented. First, the three major categories of stretchable supercapacitors are discussed: double-layer supercapacitors, pseudo-supercapacitors, and hybrid supercapacitors. Then, the representative progress in developing stretchable electrodes with low-dimensional (0D, 1D, and 2D) nanomaterials is described. Next, the design strategies enabling the stretchability of the devices, including the wavy-shape design, wire-shape design, textile-shape design, kirigami-shape design, origami-shape design, and serpentine bridgeisland design are emphasized, with the aim of improving the electrochemical performance under the complex stretchability conditions that may be encountered in practical applications. Finally, the newest developments, major challenges, and outlook in the field of stretchable SC development and manufacturing are discussed.

The recent boom in deformable or stretchable electronics, flexible transparent displays/screens, and their integration into the human body has facilitated the development of multifunctional energy devices that are stretchable, transparent, wearable, and/or biocompatible while meeting the energy or power requirements. The development of soft energy systems begins with the preparation of relevant conductors and the design of innovative device configurations. In this study, recent advances and trends in stretchable and transparent electronic and ionic conductors are reviewed coupled with the growing efforts to use them for soft energy storage and conversion systems. Stretchable transparent ionic conductors present possibilities for use as current collectors and electrolytes in soft electronic/energy devices, providing novel insight into biofriendly systems for an effective human–machine interaction. Moreover, representative examples that demonstrate soft energy devices based on stretchable transparent ionic/electronic conductors are discussed in detail. Furthermore, the challenges and perspectives of developing novel stretchable transparent conductors and device configurations with tailored features are also considered.

“…CNT films could buckle and become stretchable via "prestrain-stick-release'' approach [88] to assemble SSCs, which consists of three steps: 1) prestraining the elastomeric substrate; 2) transferring the active materials onto the prestrained elastomeric substrate; and 3) releasing the prestrained substrate (Fig. 3a).…”

Stretchable energy storage devices are essential for the development of stretchable electronics that can maintain their electronic performance while sustain large mechanical strain. In this context, stretchable supercapacitors (SSCs) are regarded as one of the most promising power supply in stretchable electronic devices due to their high power densities, fast charge-discharge capability, and modest energy densities. Carbon materials, including carbon nanotubes, graphene, and mesoporous carbon, hold promise as electrode materials for SSCs for their large surface area, excellent electrical, mechanical, and electrochemical properties. Much effort has been devoted to developing stretchable, carbon-based SSCs with different structure/performance characteristics, including conventional planar/textile, wearable fiber-shaped, transparent, and solid-state devices with aesthetic appeal. This review summarizes recent advances towards the development of carbon-based SSCs. Challenges and important directions in this emerging field are also discussed.
