Supercapacitors are energy-storage devices that complement rechargeable batteries, and could even partially replace them. Current supercapacitors do not have sufficient energy density, so they don’t last long enough. A novel approach for making a supercapacitor with a “breathing” electrode is far superior. As the team that developed it explain in the journal Angewandte Chemie, they drew inspiration from a lizard that brings along an air bubble to breathe from when it dives under water.
