Capillary infiltration and hydrophobic barrier for vertically stacked Au electrodes within a single piece of paper |
| 초록 |
Paper based electrodes have been researched for flexible energy storage devices such as supercapacitor. Herein, we propose a simple method that is capillary infiltration based on hydrophobic wax barrier for creating the Au electrode in the middle of the paper. The MnO2-Au-paper electrode can achieve 711 mF cm-2 of areal capacitance. Based on this method, vertically stacked Au-paper electrodes are readily fabricated within a single piece of paper. Despite randomly distributed fibrous networks, the three stacked Au-paper electrodes can be fabricated uniformly and each electrode is separated completely. The stacked electrodes can be used as the high energy supercapacitor with flexibility. Furthermore, the stacked supercapacitor can be used as not only parallel but also combined supercapacitor by changing only one condition which is the contact pad grounding. |
