This article highlights the advancements in ec^3 technology highlighted in our new PNAS paper. Thanks to optimized electrolytes, learnings from 3D imaging, and a new cast-in-electrolyte technique, ec^3 concrete supercapacitors can now achieve a 10x higher energy density and a wider range of architectural forms. “The Ancient Romans made great advances in concrete construction. Massive structures like the Pantheon stand to this day without reinforcement. If we keep up their spirit of combining material science with architectural vision, we could be at the brink of a new architectural revolution with multifunctional concretes like ec³,” said lead author Prof. Admir Masic. His co-authors include Damian Stefaniuk, James Weaver, and Franz-Josef Ulm.
