The ability to achieve high surface areas with nanotechnology brought advancements in energy storage devices and their applications. Supercapacitors have the ability to charge and discharge quickly, and hold as much energy as batteries and other chemical storage devices. This study focuses on the polymer gel electrolytes for the solid-state supercapacitors, and eliminating the use of liquid electrolytes, which could be harmful to the environment when disposed or leaked. In this research, various supercapacitors were constructed using reduced graphene oxide electrodes with different polymer gel electrolytes, and the best candidates were determined for commercial use. The comparison varied from different polymers to different weight ratios of doping materials, while testing specific resistivity and specific conductivity of the supercapacitors constructed.
