Flexible Fiber‐Shaped Supercapacitors: Structures, Materials, Fabrication Methods, and Applications

Interdisciplinary materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 13, 2025

ABSTRACT The advent of wearable electronics has generated considerable interest in the development fiber‐shaped supercapacitors (FSCs). FSCs have several applications, such as integration into power fabrics for modular energy storage, coupling with specific devices, forming composite fibers, and combining energy‐harvesting fibers to develop integrated storage‐usage fabrics. This review provides a comprehensive overview based on their fundamental principles, detailing various structural configurations (e.g., parallel, wrapped, twisted, coaxial) substrate materials carbon‐based, polymeric, metallic fibers), along strategies enhancing electrochemical mechanical performance. Furthermore, it outlines large‐scale fabrication techniques, wet spinning, synchronous coupling, direct ink writing, thermal drawing. identifies challenges currently facing research suggests directions future development.

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(16), P. 6873 - 6886

Published: Aug. 15, 2024

The preparation of activated carbon has long been a subject interest for researchers aiming to develop straightforward and environmentally friendly method. This study introduces an approach carbonizing glucose using potassium nitrate ignite carbonize glucose, resulting in the production fluffy carbon. Activated suitable supercapacitor can be obtained through postprocessing involving calcination pickling. An important feature this method is that it does not require use strong alkali, such as hydroxide, activation reaction following carbonization. Based on experimental results, optimal produced when proportion feedstock 50%. Furthermore, with superior physical characteristics utilized assembly organic electrolyte supercapacitors, their electrical properties analyzed. results indicate assembled by 50% raw material demonstrates best performance. Its cyclic voltammetry (CV) curve approximates rectangle exhibits almost vertical at low frequencies Nyquist plot. Additionally, analysis galvanostatic charge–discharge behavior supercapacitor, maintains equilateral triangle pattern even current density 5A/g. also show achieves 38.41 153.66 F/g capacitor-specific capacitance electrode-specific capacitance, respectively.
