Abstract

Developing more sustainable, low cost and feasible energy storage devices is a keystone of aerospace, automobile, and electronics industries. In research new materials and techniques that allow their production in large scale are studied by researchers around the world. Regarding materials, supercapacitors, for instance, may have carbon based materials on electrodes, owing to their chemical stability, low cost, and safety; however, their specific capacitance is lower when compared to other materials. Additionally, materials that may provide higher capacitance
