For the steady supply of renewable energy such as solar energy and wind energy, energy storage and distribution system is necessary. To establish an energy storage system, large capacity supercapacitors together with secondary batteries are essential. Supercapacitors has been developed for the last 20 years, however, intensive research have been focused last 5 years. Numerous researchers are trying to develop high performance supercapacitor electrode materials. Graphene was employed to use its excellent electrical conductivity and large surface area. As the EDLC type supercapacitors showed limitations in energy density, nanocomposite materials with psedudocapacitance, especially metal sulfides, have been investigated for supercapacitor electrodes. Composites of graphene-based metal sulfides (or oxides) have been synthesized for improving the supercapacitor performance. Recently, three dimensional electrode structure has been getting tremendous attention as it provide a large surface area and large pores that enables electrolytes and charges penetrates freely. In this study, we will introduce the new electrode materials and their fabrications to supercapacitor devices.
