微型超级电容器等小型化电源因其优越的循环性能、高功率密度和可观的能量，在微电子机械系统(MEMS)和微型便携式微型设备中的需求越来越高。在这项研究中，我们利用ZIF-8衍生的碳作为活性材料的来源，通过简单的电泳法制备了柔性微超级电容器。沉积的高比表面积的ZIF-8衍生碳颗粒对获得高的电化学性能起着决定性的作用。使用ZIF-8衍生碳颗粒的简单直接的电泳沉积过程在微型超级电容器上生成多孔碳膜，从而导致优异的电化学性能。
Miniaturized power supplies, such as microsupercapacitors, are highly demanded in micro-electro mechanical systems (MEMS) and micro portable microdevices due to their superior cyclability, high power density, and considerable energy. In this study, we utilize ZIF-8 derived carbon as a source of active material to fabricate flexible microsupercapacitors via a simple electrophoresis method. The deposited ZIF-8 derived carbon particles with high surface area play a decisive role in achieving high electrochemical performances. The simple and straightforward process of electrophoretic deposition using ZIF-8 derived carbon particles generates porous carbon films on microsupercapacitors, which leads to a superior electrochemical performance.
