Supercapacitors are getting significant attention in recent years due to their quick charge/discharge capabilities, long cycle lives and are environmentally friendly. Supercapacitors can provide necessary power in short bursts. Aiming to reduce the weight and volume of traditional lithium- ion batteries, supercapacitors are already being used in hybrid vehicles, laptops, airplanes, electric trains, and anywhere a sudden burst of power is needed in a very short time [1-7]. These properties make supercapacitors well suited for electric powered UAVs with the advantage of reducing weight and volume of the device. Currently, supercapacitor manufacturing depends on the chosen graphene and the creation of the electrolyte, and has limitations in terms of efficiency, operational costs, and scalability. We are optimizing a novel approach for mass production supercapacitors, using graphene sheets and Polytetrafluoroethylene (teflon) which acts as both an electrical insulator and a good ionic conductor. The use of a liquid electrolyte limits the recharging speed and operating temperature but will introduce a higher specific capacitance when compared to a traditional capacitor. The current research focuses on the ease of production of supercapacitors through the development of a superior liquid electrolyte.
