Scientists at Tohoku University in Japan have unveiled a lithium-sulfur battery prototype boasting an energy density of around 674 watt-hours per kilogram (Wh/kg)-more than double the typical 200-300 Wh/kg seen in commercial lithium-ion cells. This breakthrough hints at significant progress toward higher-capacity, lighter batteries, though the technology is still confined to the lab. Lithium-sulfur batteries […]
