This thesis is divided into two chapters. Chapter 1 is about energy storage device such as the electrochemical capacitor (EC) and the electrode materials used for its construction. The basic principle of supercapacitor performance, double-layer capacitance and pseudocapacitance phenomena are described in the introduction. Activated carbons, nanotubes, conducting polymers and metal oxides as well as their composites were considered as electrode materials. Symmetric and asymmetric configurations were taken into account. The different electrolytes were used for assembly of EC. Chapter 2 shows different ways for enhancement of the capacitance, energy and power of supercapacitor using various electrode materials and electrolytic solutions.
