Abstract
Super capacitors have the ability of high power densities for longer charging (or) discharging cycles. Material used in the super capacitors effects the performance of the device. It is obvious that the material used in super capacitors shall increase the energy density for smaller volumes while maintain the cycle stability. The right structure of super capacitors should exhibit best mechanical and electrical properties. The analysis of the above properties can be discussed by looking into the microstructure, elemental structure, etc. of the materials used. In this paper, scanning electron microscopy and energy dispersive X-ray analysis are performed on a super capacitor to study the microstructure and elemental parameters. This analysis will help in determining the electrical and mechanical properties of the super capacitors.
