Resembling broken eggshells, graphene structures built around bubbles produced a lithium-air battery with the highest energy capacity to date, according to scientists at Pacific Northwest National Laboratory and Princeton University. This black, porous material could replace the traditional smooth graphene sheets in lithium-air batteries, which become clogged with tiny particles during use. As an added bonus, the team’s new material does not rely on platinum or other precious metals, reducing its potential cost and environmental impact.
