제목 Hydrophobic Barrier Assisted Formation of Metal Electrodes within A Single Layer of Paper for Highly Efficient Flexible Supercapacitor
초록 Flexible energy storage devices have been interested to apply for wearable devices. Paper is emerging as a next-generation material. Due to porosity, paper have selected to complement low energy performance of supercapacitors. We introduce a paper-based supercapacitor fabrication technology that separates two metal electordes with a hydrophobic barrier. The key point is to deposit electrode in the desired space within a single paper. Other devices that require multi-layers no longer need to increase their size. The solid-state supercapacitor device can be fabricated by infiltration of gel electrolyte. The device exhibits a capacitance 560.2mFcm-2 and excellent cycling performance with 95.2% retention after 2000cycles and stability under the mechanical test. The maximum power and energy density of our device are measured to be 1.597mWcm-2 and 28.74μWhcm-2. In this work, it can be developed for batteries or other wearable electronic devices that require the flexibility and multi-layers.
