Clean tech company Adionics on Sept. 9 said it has developed technology that extracts high-purity lithium from black mass, a mixture of cathode and anode materials from shredded lithium-ion batteries.

“The new version of the Flionex represents a significant leap forward in promoting a truly circular economy for lithium-ion,” said Adionics CEO Gabriel Toffani. “The versatility, combined with the ability to process battery black mass, positions Adionics at the forefront of sustainable lithium production.”

The Paris-based company said its liquid-liquid process, which operates without acids, achieved lithium recoveries of up to 98% across a range of brine concentrations. The lithium can be extracted at the early, mid and late stages of the recycling process, and it is suitable for immediate reuse in new batteries.

“The development comes at a critical time as the demand for lithium in electric vehicles and renewable energy storage continues to grow,” the company said. “Adionics’ technology offers a solution to the growing challenge of battery recycling, providing a domestic alternative to overseas processing and reducing reliance on new lithium mines.”
