Recent Progress in Textile-Based Flexible Supercapacitor

Abstract

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.

Emerging washable textronics for imminent e-waste mitigation: strategies, reliability, and perspectives

“…50 Practically, multidimensional textile insulators can be transformed into a versatile intelligent clothing platform via the integration of electroactive materials on curved brous surfaces. To date, numerous techniques have been investigated to integrate electroactive materials with textiles, leading to the invention of wearable batteries, 51 sensors, 52,53 Joule heaters, 54 energy harvesters, 55 implants, 56 supercapacitors, 57 antennas, 58 and dry ECG electrodes. 59 The electrochemical fabrication of the pristine textile is carried out in diverse textile processing phases (e.g., spinning, winding, and readymade garments) according to the requirement of the textronics pattern and implementation (Table 1).…”

Carbon-Yarn-Based Supercapacitors with In Situ Regenerated Cellulose Hydrogel for Sustainable Wearable Electronics

“…Therefore, an additional requirement when producing, integrating, and disposing electronic devices that are integrated in/on textiles is to design a sustainable strategy by following a circular economy path that prioritizes reuse, repairing, and recycling. − Moreover, fibers/textiles that can store and release electrical energy are indispensable to effectively power integrated electronic systems for wearable smart clothing, capable of detecting and monitoring human activity/health and environmental conditions. Several energy-storage devices, namely, supercapacitors (SCs), have already been demonstrated in/on fiber/textile substrates (e.g., cotton fibers, , carbon fibers/yarns, − polymer fibers, ultrafine metal fibers). − The SCs stand out as promising energy-storage devices since they display higher power density, fast charging–discharging rate, long lifecycle, and good safety when compared to batteries. , …”

Nanomaterials-patterned flexible electrodes for wearable health monitoring: a review

“…Electrodes based on textiles are currently ubiquitous for monitoring physiological and environmental phenomena, and human–computer interactions [ 10 – 13 ], personal thermal management [ 14 – 17 ], antennas for tracking and communicating [ 18 – 21 ], energy harvesting [ 22 – 25 ], and storing devices [ 26 – 29 ]. Fiber-shaped energy storage [ 30 – 33 ] and harvester [ 22 , 34 , 35 ] devices provide opportunities to fabricate self-powered wearable devices [ 36 – 38 ] eliminating the need for an external power source. Fiber electrodes have demonstrated sensitivity toward physical changes [ 12 ], chemical compounds in the body fluids [ 39 – 42 ], and biopotential signals [ 43 – 48 ], which provide opportunities for real-time health monitoring, diagnosis, and therapeutics [ 49 – 53 ].…”
