QuantumScape EV Batteries Can Be Charged Super Fast. Why That Matters.

Electric-vehicle-battery start-up QuantumScape can get its lithium metal solid-state batteries to 80% full in 15 minutes without compromising battery life or safety.

That’s big. If QuantumScape’s (ticker: QS) technology scales up, it means a typical EV with some charge left—and with 200 or 300 miles of designed per charge range—could pick up about 200 miles of driving range in less than 15 minutes. That should be fast enough to alleviate much of the range anxiety consumers sometimes feel when thinking about purchasing a battery powered car…

“These results blow away what was previously thought to be possible in a solid-state battery,” Venkat Viswanathan, battery expert and professor of materials science at Carnegie Mellon University, said in the news release. “This data shows the capability to charge to 80% capacity in 15 minutes, corresponding to an astonishingly high rate of lithium deposition of up to a micron per minute.”
