New lithium-sulfur battery charges fully in 12 minutes, lasts over 1,000 cycles

South Korean researchers have developed a nitrogen-doped porous carbon material to enhance lithium-sulfur battery charging speed. This breakthrough addresses slow charging issues that impeded commercialization. The new battery charges in 12 minutes, retains 82% capacity after 1,000 cycles, and provides over 7 mAh cm–2 for 80 cycles with high sulfur content. This innovation could make lithium-sulfur batteries a viable alternative to lithium-ion batteries, offering higher energy density and lower costs for electric vehicles and other applications.
