Flexible planar micro-supercapacitors based on carbon nanotubes

Abstract: The boom in ultra-thin electronic devices and the growing need for humanization greatly facilitated the development of wearable flexible micro-devices. But the technology to deposit electrode material on flexible substrate is still in its infancy. Herein, the flexible symmetric micro-supercapacitors made of carbon nanotubes (CNTs) on commercial printing paper as electrode materials were fabricated by combining tetrahedral preparator auxiliary coating method and laser-cutting interdigital configuration technique on a large scale. The electrochemical performance of obtained micro-supercapacitors can be controlled and tuned by simple choosing the different model of tetrahedral preparatory to obtain CNTs film of different thickness. As expected, the micro-supercapacitor based on CNTs film can deliver an areal capacitance of up to 4.56 mF cm-2 at current of 0.02 mA. Even if, micro-supercapacitor undergo continuous 10000 cycles, the performance of device can still remain nearly 100%. The as-demonstrated tetrahedral preparator auxiliary coating method and laser-cutting interdigital configuration technique provide new perspective for preparing microelectronics in an economical way. The paper electrode appended by CNTs achieves steerable areal capacitance, showing broad application prospect in fabricating asymmetric micro-supercapacitor with flexible planar configurations in the future.
