| 제목 | Vertically layered supercapacitor within a single sheet of paper by using hydrophobic barriers |
| 초록 | Paper, which is thin, light, flexible, and highly porous, has emerged as a next-generation energy-storage material. Here, we introduce a facile technology for fabricating a supercapacitor based on a single sheet of paper, in which the electrodes are vertically separated by the patterning of hydrophobic barriers. Two electrodes can be simultaneously sectionalized as active layers and current collectors in a single-layer porous paper supercapacitor, such that the gel electrolyte infiltrates the device without any additional assembly. The solid-state supercapacitor with vertically layered electrodes exhibits a large areal capacitance of 560.2 mF cm−2, and stable flexibility and foldability. The maximum power and energy densities were 1.597 mW cm−2 and 28.74 μWh cm−2. This technology is promising for applications such as flexible energy storage devices and other paper-electrode applications such as batteries and wearable electronic devices. |
