CO2 + H2O = cleaner recycling of dead lithium batteries?

Chinese scientists have found a way to recycle lithium batteries using only carbon dioxide and water – eliminating the need for harsh, polluting chemicals to extract the lithium and upcycle cathode materials. The team from the Chinese Academy of Sciences and Beijing Institute of Technology said they used a “three-in-one” strategy to improve lithium recovery, upgrade transition metals like cobalt and nickel, and sequester carbon to eliminate waste by-products. Their method achieved a lithium...
