Saltwater is a lithium-ion battery’s worst enemy. This aqueous prototype embraces it.
Hurricane Ian caused billions of dollars in damage when it hit Florida in the fall of 2022. Along with $112 billion in damages, 152 fatalities, and countless uprooted lives, the fallout included at least 12 electric vehicle fires caused from lithium-ion batteries coming into contact with saltwater flooding in from the ocean. It’s an unfortunate downside to EVs’ lithium-ion power sources, especially as coastal flooding increasingly becomes the norm, but a promising new alternative could one day be available to carmakers. Thanks to novel breakthroughs at the University of Central Florida electric cars could one day embrace saltwater instead of avoiding it entirely. The result, says research lead Yang Yang, an associate professor at UCF, is a potentially revolutionary battery to “remain safe even if they are used improperly or are flooded in saltwater.” While it is still likely a while until we start seeing Ford F-150 Lightning trucks barreling down flooded roads thanks to aqueous saltwater batteries, the new innovations could soon address one of lithium-ion batteries’ most concerning hazards, thus encouraging the rapidly-approaching EV transition.
