Abstract: Supercapacitors (SCs) have a fast charge-discharge rate and hence a great potential for high power energy storage applications. However, the low energy density of SCs has limited their developments. On the other hand, the fast development of flexible electronic devices requires flexible energy storage devices. The development of SCs with both high energy and power densities as well as a long cycle life therefore become an area of active research. This article first introduces the principle of SCs and their classification. A review is then performed on the latest progress in electrodes and preparation methods of carbon fibers based flexible SCs. Finally, the prospects and challenges associated with flexible SCs in practical applications are also discussed.
