Scientists at Central South University, Guizhou Normal University, and the National Engineering Research Center of Advanced Energy Storage Materials have developed a new method for recycling lithium-ion batteries, recovering nearly 100% of the lithium, 96.8% of nickel, 92.35% of cobalt, and 90.59% of manganese in just 15 minutes. The eco-friendly process uses tiny micro batteries and an amino acid, avoiding harsh chemicals and toxic byproducts.
