dc.description.abstract Flexible supercapacitors (SCs) are one kind of promising energy storage device for portable electronics. To gain a supercapacitor with high flexibility and electrochemical performance, such as high energy density, power density and cycling stability has drawn massive attention. However, to achieve this goal, there are challenges in the preparation of flexible electrodes and solid-sate electrolyte as well as the design and fabrication of flexible SCs. This doctoral thesis work is focused on the fabrication of flexible SCs with high electrochemical performance based on reduced graphene oxide (RGO) hydrogel. Two composite RGO hydrogel film electrodes with redox-active materials, polyaniline (PANI) or manganese dioxide (MnO2) were prepared. Suitable gel/hydrogel electrolytes were prepared to match the designs for each flexible supercapacitor. In the study, important factors on the flexibility of final devices have been discussed. Two strategies, free-movement configuration and the reduction of the thickness of entire devices were applied to improve the flexibility of the assembled SCs. en_US
