Profit is not a dirty word in EV-battery recycling. In fact, Jessica Durham, a materials scientist at Argonne National Laboratory, says it's key, just as it is in traditional vehicle and 12-volt lead-acid battery recycling.
"To be able to recycle EV batteries, there's going to have to be some type of profit," said Durham. "Or else people are not going to want to do it. And the more profit we have, the more people will be willing to adopt this technology."
Argonne's researchers say they've found an old mining process that cuts down the cost of processing used batteries and preserves their high-priced metallic compounds, unlike traditional methods that break them down into their lower-cost constituent parts. This clever new methodology has caught the interest of battery makers and the auto companies that use these recycled materials.
The recycling of lithium ion batteries has yet to scale up. Only about 5 percent are recycled. Today most find secondary li…
