摘要:

與傳統平面型超級電容器的兩維結構不同，纖維狀超級電容器具備獨特的一維結構，使它不但具備傳統超級電容器的高功率密度、快速充放電和長循環壽命等優勢，還可以滿足微型化、集成化和柔性化的可穿戴要求。自纖維狀超級電容器問世以來，為了優化它的性能并促進其能夠真正實際應用，近年來研究人員陸續開展了持續的研究工作，本文對此予以綜述。首先介紹了纖維狀超級電容器的工作原理，并討論了基于不同制備方法構建的平行、纏繞和同軸三種結構的纖維狀超級電容器，進而重點根據電極材料的不同對纖維狀超級電容器進行了分類比較，詳細討論了其柔性、穩定性和比電容等相關性能。并舉例列出纖維狀超級電容器的幾個發展方向，最后提出了該領域依然存在的問題并給出了它未來的研究方向。

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.
