“…As a result, the longest section of functional supercapacitor fiber reported in the literature is ≈100 cm. [8,13,14] In addition, while scalable fabrication methods have been described to prepare a single component of a supercapacitor [9,12] no single component can ultimately satisfy all of the requirements placed on the full device which requires further assembly. The practical potential of fiber-based supercapacitor devices has yet to be realized due to outstanding challenges.…”

“…Specifically, we employ a top-down method that involves assembling a macroscopic preform, which is subsequently thermally drawn into fiber. Fabrication approaches that involve the packing of a gel electrolyte and a solid electrode [8,13] may result in defects that are concentrated at the gel/ electrode interface. The fluid-based drawing method allows for these packing defects to be eliminated in a manner resembling zone refinement.…”

“…The copper microwires in the current collector design allow for high axial electronic conductivity. While performance over length is cited as an outstanding challenge in supercapacitor fibers, [8,13,14] these issues appear to be significantly mitigated in the structure that we introduce. Finally, the COC cladding, which encases the device from preform to fiber, effectively contains the electrolyte and provides a hermetic sealing, serving as a moisture and oxygen barrier.…”

Supercapacitor fibers, with short charging times, long cycle lifespans, and high power densities, hold promise for powering flexible fabric‐based electronics. To date, however, only short lengths of functioning fiber supercapacitors have been produced. The primary goal of this study is to introduce a supercapacitor fiber that addresses the remaining challenges of scalability, flexibility, cladding impermeability, and performance at length. This is achieved through a top‐down fabrication method in which a macroscale preform is thermally drawn into a fully functional energy‐storage fiber. The preform consists of five components: thermally reversible porous electrode and electrolyte gels; conductive polymer and copper microwire current collectors; and an encapsulating hermetic cladding. This process produces 100 m of continuous functional supercapacitor fiber, orders of magnitude longer than any previously reported. In addition to flexibility (5 mm radius of curvature), moisture resistance (100 washing cycles), and strength (68 MPa), these fibers have an energy density of 306 μWh cm−2 at 3.0 V and ≈100% capacitance retention over 13 000 cycles at 1.6 V. To demonstrate the utility of this fiber, it is machine‐woven and used as filament for 3D printing.

In the backdrop of the growing requirement of flexible and wearable energy storage systems, textile-based supercapacitors having characteristic flexibility, superior charging-discharging rates, and low cost are ideal energy storage devices for wearable applications. Lightweight and flexible textile-based supercapacitors characterized by high conductivity, thermal, and environmental stability with negligible degradation under repeated use are required for multifunctional wearable electronics. Herein, supercapacitor based upon textile fabrics will be reviewed from the perspective of electrochemical, mechanical, and thermal properties without compromising flexibility, durability, and comfort of textile fabric.

With the rapid advances in safe, flexible, and even stretchable electronic products, it is important to develop matching energy storage devices to more effectively power them. However, the use of conventional liquid electrolytes produces volatilization and leakage that are dangerous and requires strict packaging layers that are typically rigid. To this end, solid electrolytes that can overcome these problems have attracted increasing attention in recent decades. In this review article, three main types of solid electrolytes (i.e., inorganic, polymer, and composite electrolytes) are first described and compared in terms of their structures and properties. The advantages of solid electrolytes to make safe, flexible, stretchable, wearable, and self‐healing energy storage devices, including supercapacitors and batteries, are then discussed. The remaining challenges and possible directions are finally summarized to highlight future development in this field.
