Title: HIGH FREQUENCY SUPERCAPACITORS AND METHODS OF MAKING SAME
Abstract:
High-frequency supercapacitors that can respond at kilohertz frequencies (AC- supercapacitors). The electrodes of the AC-supercapacitors include edge oriented graphene (EOG) electrodes or carbon nanofiber network (CNN) electrodes. The EOG electrodes are formed by utilizing a plasma and feedstock carbon gas to carbonize cellulous paper and deposit graphene implemented in one step. The CNN electrodes are formed by pyrolyzing a carbon nanofiber network utilizing a plasma.
