제목 Ribbon-like activated carbon with porous graphitic structure for supercapacitors
초록 Ribbon-like activated carbon has been successfully developed by a two-step activation process based on alkali activation and an electrochemical activation route. The multi-structure of the RAC features a porous graphitic structure with the coexistence of micropores and graphitic structures, mainly originating from the loose packing of the graphite sheets as a result of the degree of graphitization controlled by the carbonization conditions. RAC provides the tremendous benefits of excellent cycle life, high power, and high energy density for supercapacitors, because of its graphitic architecture comprised of micropores and ring-shaped crystalline structures. In addition to investigating the improved electrochemical performance, we observed an interesting feature of the RAC: the obtained RAC has a high structural stability as shown by ex situ high-resolution transmission electron microscopy. These extraordinary results are attributed to the unique structure of RAC.
