title = "A Sustainable Method to Recover the Critical Metals From Spent Lithium-ion Batteries by Glycine and Sodium Metabisulfite in a Near-Neutral Solution",
abstract = "A green leaching system consisting of glycine and sodium metabisulfite was proposed to recover critical metals from spent lithium-ion batteries (LIBs). The preliminary leaching study using synthetic LiCoO2 revealed that metal extraction was 99.9% for cobalt and 99.8% for lithium under optimal conditions. Following metal dissolution, cobalt was separated using an acidification-precipitation technique involving oxalic acid as the precipitant, and glycine was recycled into the leaching step. This leaching system operates at near-neutral conditions and is cost-effective compared with the conventional method, making it an economical alternative for recycling spent LIBs.",
