Li-S Battery Shows Cycle Performance Comparable To Li-Ion, Double The Energy Density

Good news is coming from the battery front where researchers in South Korea and Italy announced a milestone for lithium–sulfur cells. Their new Li-S cells, with energy density over two times higher than lithium-ion (497 Wh/kg), ran through 500 cycles with capacity remaining at about 85% (∼750 mAh g–1). We… …read more
