A Novel Method for Battery Recycling

Watch this video to see ORNL researchers rapidly peel off the cathode film from a battery’s aluminum current collector, leaving it intact for easier reuse. The liquid is ethylene glycol, a raw material commonly used in antifreeze.

“You want something that is similar to current EV battery materials in terms of structure, energy density, electrochemical behavior and voltage range,” said lead researcher, Nitin Muralidharan .
