What kills EV battery range? Real-time images pinpoint lithium metal weak spots

A crucial clue to simultaneously increasing electric vehicle (EV) driving range and battery lifespan has been discovered. A research team at KAIST has observed the exact moment of degradation in lithium metal batteries at the nanoscale (approximately 1/100,000th the thickness of a human hair) and identified the fundamental cause of performance decline. This is evaluated as a significant turning point in accelerating the commercialization of next-generation batteries.
