CAN WE USE EGGSHELLS FOR ENERGY STORAGE

hemical and materials engineering at the University of Alberta, in Edmonton, Canada, is working on a way to turn waste eggshell membranes and egg whites into materials for high-performance supercapacitors. Supercapacitors offer high power density, charging and discharging far faster than rechargeable batteries. Unfortunately, they store much less energy. Mitlin thinks the membranes inside eggshells could help crack that problem. “If you could keep the very nice power of a supercap but extend the energy density even to be that of a mediocre lithium-ion battery, you’d really enable the applications world in the automotive sector and in consumer products,” Mitlin told attendees at the Materials Research Society’s Fall Meeting in Boston last week.READ MORE
