Abstract:
Different from the two-dimensional planar structure of conventional supercapacitors (SCs), fiber-shaped supercapacitors (FSCs) have one-dimensional unique format. Therefore, FSCs not only possess high power density, fast charge-discharge, long cycle life, but also meet with the development of the emerging wearable electronics, e.g., miniaturization, integration and flexibility. In order to optimize the performance of the FSCs and promote such energy storage devices to practical use, much efforts have been devoted to FSCs since its advent. This paper gives a review on the status quo of the FSCs. Firstly, the basic principle of the FSCs is introduced. Secondly, the configuration of the FSCs is provided, which is divided into three categories, i.e., parallel, twisted and coaxial design. Thirdly, some typical examples are descripted and comparison is made on the electrochemical performance, flexibility and stability. Finally, the remained problems and challenges are discussed.
