Researchers from Korea's DGIST, Kyungpook National University, France's University of Bordeaux (CNRS), Collège de France and Japan's Komaba Institute for Science (KIS) recently designed a solar-powered faradaic supercapacitor, with a graphene layer as its anode, that can reportedly achieve a power density of 2,555.6 W kg and an energy efficiency of 63%. The system uses nickel-based compounds to enhance the electrochemical performance of its electrodes.
