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.
