Bendable Electrode Consisting of Graphene Nano-Powder and Cellulose Binder |
| 초록 |
The development of bendable graphene electrode is reported. The 2-hydroxyethyl cellulose solution is used as a binder of the graphene to maintain the anchoring force between the graphene layer and the filter paper. The graphene electrode shows a brilliant capacitance from both the low surface resistance by flat surface and the high electrochemical activity by gradient porous structure. This unique structure offers an enhanced conductivity and good electrical contact between electrode and electrolyte. Thus the graphene electrode exhibited a good cyclic stability. The gravimetric capacitance of graphene electrode keeps its recovery within ca. 96% capacitance. The morphology of graphene electrode is investigated using a scanning electron microscope, and surface resistance of the graphene electrode as a function of graphene content is determined. |
