Mild solvent extracts cobalt from batteries

University researchers in Texas are developing a nontoxic leaching solution to recover cobalt and lithium from end-of-life batteries.

Two Rice University scientists have formulated a solvent that can extract material from the cathodes used in lithium-ion batteries.

The solution is termed a “deep eutectic solvent” and is made from choline chloride and ethylene glycol.

It has been shown to recover a “significant” amount of cobalt from used batteries, according to a university release.
