US Johns Hopkins Uses Wine Waste to Recycle Battery Metals

Johns Hopkins researchers use tartaric acid from wine waste to recycle cobalt and nickel from batteries. The electrochemical method achieves over 99% purity for cobalt and cuts costs dramatically compared to conventional solvent extraction. The process could make EV battery recycling simpler and more sustainable.
