“Supercapacitor” is receiving attention as a next-generation energy storage device for automobiles, communication devices, IoT, etc. It has high power density and fast charging and discharging speed, but its carbon and metal electrode materials require expensive electrode manufacturing process technologies. The research team of Professor Park Sung-june from the Department of Polymer Nano Science and Technology, and the Department of Nano Convergence Engineering at JBNU, succeeded in synthesizing conductive polymer electrode materials for the supercapacitor. It can be manufactured at low costs through the solution process and can be easily malleable by simple chemical functionalization. Park said, “The energy storage materials based on organic polymers will facilitate the manufacture of flexible electronic devices, reduce manufacturing costs, and be used to make portable and wearable devices.”
