Abstract:

Traditional supercapacitors cannot meet the needs of wearable electronic products because of their poor flexibility and low safety. Therefore, solid-state flexible supercapacitors emerge and attract many researchers’ attention due to their unique flexibility, ductility and high security. In this paper, the research significance and the main structures of solid-state flexible supercapacitors are introduced. Besides, this paper points out that two-dimensional interdigital supercapacitors are suitable for micro-electronic devices, and one-dimensional linear ones have better flexibility and adaptability. After that, the research progress of electrodes and electrolytes for solid-state flexible supercapacitors is summarized, and the existing problems are also discussed. It is concluded that the key to further development in this field is to improve the capacity performance and cycle stability of electrodes, as well as the strength, conductivity and electrochemical stability of electrolytes.

Key words: supercapacitor, electrolyte, electrode material, solid, electrochemical, safety
