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).
