Scientists in the Materials Engineering Research Facility at Argonne are scaling up MTU’s innovative separation process, paving the way for the large-scale recycling of EV batteries.
In a new paper published in the peer-reviewed scientific journal Energy Technology, MTU and ReCell researchers detail their discovery: a method of separating individual cathode materials using a new twist on an old process called froth flotation. Used for many years by the mining industry to separate and purify ores, froth flotation separates materials in a flotation tank based on whether they repel water and float, or absorb water and sink.
Once the cathode materials were separated, the researchers determined through testing that the process had a negligible impact on the electrochemical performance of the materials. Both also had high purity levels (95 percent or above).

How do we make battery recycling cost effective? Scientists at the ReCell Center have taken another step towards that goal.
