Fluoride discovery could lead to much longer-lasting EV batteries
Researchers have announced a new battery breakthrough that focuses on the negative. Rather than using lithium, the most electro-positive element on the periodic table, they used fluoride, the most electro-negative. It can store more energy than its lithium doppelgänger, but until now, batteries needed to run hot at 150 degrees Celsius or more. Honda, Caltech and NASA scientists discovered a way to make it work at room temperature, which could eventually yield more energy dense and environmentally safe batteries for EVs and other devices.
