What if electric cars could travel twice as far, drones could fly for hours, and robots could work tirelessly without frequent recharging? A research team from Tianjin University, in collaboration with partners, has published groundbreaking findings in Nature, leading to the development of a lithium metal pouch cell with an energy density exceeding 600 Wh/kg and a battery pack achieving 480 Wh/kg. This innovation represents a 200 percent to 300 percent improvement in both energy density and endu
