> The researchers say that using silver-carbon instead of lithium metal in a prototype pouch yields a battery with a higher capacity, lengthens the cycle life, and makes the battery safer. The layer of silver-carbon measures only five micrometers thick, but if it can accomplish in the real world what the Samsung team pulled off in the lab, it could substantively change EVs in the future. As others noted, it's also 50% smaller. The headline is kind of misleading the range is only part of the story.
