Abstract:

With the rapid development of manufacturing technology, portable electronic devices are developing in the direction of stretchability, light weight, miniaturization, and intelligence, and stretchable electronic devices that can stretch, bend, and fold have emerged. Different from ordinary supercapacitors, stretchable all-solid supercapacitors have stronger anti-deformation ability, and have received widespread attention for potential applications in the fields of wear and medical treatment. This paper summarizes the research and development status of stretchable all-solid supercapacitors by discussing recent related literatures. It briefly introduces all solid-state supercapacitors, focusing on stretchable gel electrolytes, including three systems of hydrogel, organic gel and ion gel electrolytes. At the same time, it also focuses on the research status of stretchable electrodes, including stretchable electrodes based on gels, based on elastic substrates and based on structural design. Some challenges and future development directions that stretchable all-solid supercapacitors still need to face in the future are discussed, and the research focus of stretchable all-solid supercapacitors is to improve energy density, practicability and versatility. It is hoped that more innovative research will be stimulated to promote the development and practical application of stretchable supercapacitors.
