Outline of Research at the Start	Nanostructuring the electrode materials and their functionalizations are the keys to advance the development of supercapacitors in addition to optimizing the combination between the electrodes and the used electrolytes. We realize that controlling the nanomaterials' size and assemblies is the best approach to develop a high-performance supercapacitor. We will achieve a hierarchical porous structure and use the extraordinarily large surface-area-to-volume ratio. We should exploit the nanomaterials' quantum-size-effect to significantly enhance the EDL supercapacitor's capacitance.
