Mining Techniques Used to Recycle Lithium Ion Batteries

A group of researchers from Michigan Technological University, with the assistance from Lei Pan, an assistant professor of chemical engineering, are using mining techniques that are more than a century old to recycle lithium-ion batteries at low cost. These techniques were used to separate metal from ore, thus Pan had a suspicion that they will work for recycling batteries today. He suggested that his students pursue that line of inquiry. The research involved plenty of late hours and dead ends, most of the time when things worked out, it was kind of an accident. The group was trying all kinds of solvents to liberate chemicals and later found out that plain water worked the best. They used tried and true mining industry techniques to separate everything in the lithium-ion batteries : the casing, metal foils, the anode and cathode, and the lithium-metal-oxide (the most valu...
