Scientists have used a neat chemistry trick to tackle a major challenge facing future batteries. Their breakthrough paves the way for next-generation electric vehicle (EV) batteries capable of powering 500-mile (800 kilometers) journeys on a single, 12-minute charge. Lithium-metal batteries differ from standard lithium-ion batteries in that the graphite anode is replaced with lithium metal. These designs offer much higher energy density, the researchers said in a statement. For EV drivers, this...
