Using 100-year-old minerals processing methods, chemical engineering students have found a solution to a looming 21st-century problem: how to economically recycle lithium ion batteries.
Pan, an assistant professor of chemical engineering at Michigan Technological University, earned his graduate degrees in mining engineering. It was his idea to adapt 20th century mining technology to recycle lithium ion batteries, from the small ones in cell phones to the multi-kilowatt models that power electric cars. Pan figured the same technologies used to separate metal from ore could be applied to spent batteries. So he gave his students a crash course in basic minerals processing methods and set them loose in the lab.
