Chinese researchers claim a new solid-state battery can survive ultra-fast charging while delivering dramatically higher energy density, potentially reshaping the future of electric vehicles. Researchers at the Chinese Academy of Sciences claim they have developed a new solid-state lithium-metal battery capable of delivering extremely high energy density while surviving ultra-fast charging conditions – a combination the global EV industry has been chasing for years. According to the research paper published in the Journal of the American Chemical Society, the prototype battery achieved an energy density of 451.5 Wh/kg while maintaining stable cycling performance for 700 charge cycles under a 20C…
