“Fluoride batteries can have a higher energy density, which means that they may last longer – up to eight times longer than batteries in use today,” says study co-author Robert Grubbs, Caltech’s Victor and Elizabeth Atkins Professor of Chemistry and a winner of the 2005 Nobel Prize in Chemistry. “But fluoride can be challenging to work with, in particular because it’s so corrosive and reactive.”
Fluoride-based batteries have the potential to last up to 8X longer than those in use today. Imagine not having to charge your phone or laptop for weeks...
