제목 Reduced graphene oxide and contorted hexabenozocoroene composites for energy storage applications
초록 Developing energy storage materials which could have both high energy density and electric power is required to overcome disadvantages in battery and supercapacitor (SC). To achieve this goal, hybridization of inorganic, and organic has been considered. Here, we hybridized carbon materials, reduced graphene oxide (r-GO), showing SC behavior and organic semiconductor, contorted hexabenzocoronene (c-HBC), showing battery property. Especially, c-HBC derivatives were recently reported as anode materials in Li and Na ion battery where r-GO has been known as energy storage materials in SC. Composites were prepared by evaporating solvent of r-GO and c-HBC mixed DMF solutions. The amount of c-HBC was varied in composites to optimize energy storage properties. For structural analysis of composites, XPS and XRD study were conducted. In addition, to understand energy storage characteristics of these hybrid composites, Li ion battery and SC characteristics of hybrid composites were also examined.
