#Winemaking acid powers cleaner way for cobalt-nickel recovery from #BatteryWaste

Scientists use #TartaricAcid and electrowinning to split #cobalt and #nickel from battery waste for cleaner #recycling.

"Scientists have developed a cleaner way to separate cobalt and nickel from lithium-ion battery materials using an electrochemical technique boosted by a naturally occurring acid commonly associated with wine.

[...]

"The researchers say the approach could be particularly useful for '#UrbanMining,' the process of recovering valuable #minerals from discarded #electronics and spent #batteries. Countries with limited mining resources are increasingly looking to #recycling to secure supplies of critical materials.

" '#Electrowinning’s edge in urban mining gives us a practical pathway to turn battery waste into a valuable resource for cobalt and nickel, while also helping the United States reduce its reliance on foreign supply chains,' Liu says."

Electric vehicles are expected to reduce greenhouse gas emissions and air pollution, but they also pose a challenge for waste management. A new study estimates that by 2036, Australia will generate more than 100,000 tonnes of electric vehicle battery waste containing toxic and valuable materials. The study urges the government and the industry to develop strategies for recycling and reusing electric vehicle batteries.
