Abstract
Flexible and wearable electronics are poised to revolutionize various domains, but the practical implementation of these devices is hindered by the significant difficulty of energy storage devices. An effective solution can be found in the advancement of high-performance supercapacitors by developing with the qualities of being integrated, elastic, and self-healable, without requiring additional film layers. Hydrogels greatly contributed to achieving this owing to their interesting properties, conductivity, and flexibility. This short review explores the recent progressions in all-in-one supercapacitors powered by hydrogels, highlighting their functional mechanisms of self-healing, ion transmission, and synchronous deformation. We discussed the potential applications in wearable electronics, medical devices, and flexible energy storage systems, focusing on design optimization and new functionalities. Furthermore, we provide insights into future research directions, guiding the exploration of novel additives and achieving high and stable performance.
期刊介绍:
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
