Abstract
The emergence of flexible electronic devices has put forward new requirements for their power sources, and fabrication of flexible supercapacitors with excellent electrochemical performances will be a new approach to fulfill this demand. As promising candidates for high performance flexible supercapacitors, one-dimensional nanostructured materials have attracted increasing interest owing to their high specific area, efficient electron transport, and excellent mechanical strength, thus enabling them to be flexible supercapacitors with some remarkable properties, such as high energy densities, superb power densities, and great flexibilities. Moreover, based on their application demands, flexible supercapacitors can be designed into different structures, including sandwich-type, wire-shaped, and chip-type. In this regard, one-dimensional nanostructured material-based flexible supercapacitors exhibit great promise for next-generation flexible electronic devices. Herein, we summarize the recent progress in one-dimensional nanostructured material based flexible supercapacitors. The challenges and prospects of flexible supercapacitors are also discussed.
