The hidden culprit killing lithium-metal batteries from the inside

News Article, July 14, 2021 • First-of-their-kind snapshots reveal byproduct crippling powerful, experimental cells For decades, scientists have tried to make reliable lithium-metal batteries. These high-performance storage cells hold 50% more energy than their prolific, lithium-ion cousins, but higher failure rates and safety problems like fires and explosions have crippled commercialization efforts. Researchers have hypothesized why...
