Researchers Propose a "Fountain of Youth" for Lithium Batteries: Blasting Them Better with X-Rays
A team of researchers, led by the University of Nevada Las Vegas (UNLV), has come up with a possible "fountain of youth" for lithium batteries — blasting tired old cells with X-rays to restore their performance, with a view to increasing the lifespan of everything from smartphones and laptops to electric vehicles (EVs).
"Replacing battery packs on electric vehicles can cost tens of thousands of dollars. A Tesla can drive for on average 340 miles on a full charge, but after a decade, maybe it only goes 200,” project lead Michael Pravica, professor of physics at UNLV, explains. "My lab is trying to regenerate the battery's capacity so that it's basically very close to new and usable for much longer. Instead of getting 10 years of use from these cars, drivers may now be able to get 15 or 20 years, and save money in the process."
