flag Chinese scientists have created a low-energy, eco-friendly method to recycle lithium from old batteries, recovering over 95% of lithium using only carbon dioxide and water. flag The process, published in Nature Communications, mimics carbonated drinks by converting lithium into a pure bicarbonate solution while producing a reusable catalyst. flag It avoids toxic chemicals and high energy use, captures CO₂, and supports China’s climate goals. flag Researchers plan to test industrial flue gas as a CO₂ source to improve efficiency and reduce costs.
