Eggshell Storage

Eggshells for energy

Mitlin, a professor of chemical and materials engineering at the University of Alberta, Canada is working on a way to turn waste eggshell membranes and egg whites into materials for high-performance supercapacitors. Supercapacitors are devices which offer many “need-of-the-hour” features like high power density, charging and discharging which are generally faster than regular rechargeable batteries. But unfortunately they store much less energy. Mitlin thinks the membranes inside eggshells could help crack this problem. “If you could keep the very nice power of a supercapcitor but extend the energy density even to be that of a mediocre lithium-ion battery, you’d really… read more
