Flexible and Transparent Supercapacitor

Norteastern University mechanical and industrial engineering professor Yung Joon Jung and his team have created a thin and flexible energy-storage system. The technology is based on a nanomaterial developed in Jung's lab two years ago, which they call a nanocup. The first step to making a nanocup involves etching nanoscopic divots into an aluminum film through oxidation. By tweaking the voltage and time of this process, researchers can tailor the size of the cups. The second step is to layer carbon atoms onto the aluminum mold. In this demonstration, the research team uses the prototype supercapacitor to power a light.
