“…[9][10][11][12][13][14] It remains a great challenge to develop highly elastic wire-shaped electronics because most of the existing wires are either stretchable, but nonconductive (e.g., elastic polymer fibers), or vice versa (e.g., metal wires). A few studies on stretchable conductive wires have been reported, [15,16] whereas the development of stretchable wire-shaped electronics has been much less discussed in the literature. However, if such electronics (e.g., supercapacitors) are realized, they could be very useful as power sources for various miniaturized electronic devices, ranging from microrobots, through wearable electronic textiles, to integrated energy conversion and storage systems.…”

A general approach toward extremely stretchable and highly conductive electrodes was developed. The method involves wrapping a continuous carbon nanotube (CNT) thin film around pre-stretched elastic wires, from which high-performance, stretchable wire-shaped supercapacitors were fabricated. The supercapacitors were made by twisting two such CNT-wrapped elastic wires, pre-coated with poly(vinyl alcohol)/H3PO4 hydrogel, as the electrolyte and separator. The resultant wire-shaped supercapacitors exhibited an extremely high elasticity of up to 350% strain with a high device capacitance up to 30.7 F g(-1), which is two times that of the state-of-the-art stretchable supercapacitor under only 100% strain. The wire-shaped structure facilitated the integration of multiple supercapacitors into a single wire device to meet specific energy and power needs for various potential applications. These supercapacitors can be repeatedly stretched from 0 to 200% strain for hundreds of cycles with no change in performance, thus outperforming all the reported state-of-the-art stretchable electronics.

“…Meanwhile, the specific capacitance of the stretchable supercapacitors with or without applied strain does not alter up to 1000 charge-discharge cycles, which concludes an excellent electrochemical stability [28]. To further enhance the stretchability while retaining high electric conductivity, the architectures of this wave structural configuration are carefully tailored by finely designing the CNTs with various morphologies and spatial distributions, such as CNT fibers [32], CNT ribbons [33], aligned CNTs [34], and hierarchically reticulated CNTs [35]. The similar buckling strategy can also be applied to other energy storage devices.…”

With the continuous progress of the energy use and demand, functionalized energy storage and conversion devices (ESCDs) are urgently needed. In the meantime, stretchable ESCDs are attracting intensive attention due to their great potential for specific applications, such as wearable electronics, an electronic skin, implant electronics, and other collapsible gadgets. Design and synthesis of nanomaterials are at the core in the development of highly stretchable supercapacitors, batteries, and solar cells for such applications. This chapter first provides a brief summary of research development on the stretchable ESCDs in the past decade through various strategies of device design and manufacturing approach. After that, the focuses are on the advanced engineering of nanomaterials as active materials to achieve the stretchability of these ESCDs while maintaining a stable and functional performance. Finally, some of the challenges and the important directions in the areas of design and synthesis of nanomaterial facing the stretchable ESCDs are discussed concisely. IntroductionWith the rapidly increasing population and economic development, the world's energy consumption is escalating dramatically, resulting in one of the most serious global challenges of our time-energy scarcity. Hence, a crowd of research in the areas of advanced technologies for energy storage (e.g., batteries and supercapacitors) and conversion (e.g., solar cells) during the past decade has been driven by the

“…It turned out that massive buckling took place in the fractured CNT fiber segments. Taking advantage of the "hinge-like" structure developed in the buckled fiber, Zu et al [16] developed a stretchable conductor, which showed very little variation in electric resistance under stretchingthen-releasing cycles with a maximum strain of 40%. Expanding the capability of CNT fiber based stretchability, Xu et al [17] studied a stretchable supercapacitor consisting of two undulating CNT fibers.…”
