Adionics, a pioneer in sustainable direct lithium extraction (DLE) technology, today
announced the company has successfully developed its DLE technology capable of
extracting high-purity lithium from battery black mass without toxic waste or the need for
overseas processing. (According to the US Environmental Protection Agency, black mass
is the term to describe the filter cake-like material made up of the anode and cathode materials when lithium batters are shredded.)

While existing hydrometallurgical processes have successfully recovered metals such as
cobalt, manganese, and nickel from battery waste, the efficient recovery of lithium has
remained a persistent challenge. Adionics' new Flionex®—liquid media invented by
Adionics that enables efficient lithium recovery in a DLE process—enables the efficient
recovery of high-purity lithium from black mass at different hydrometallurgical process stages.

Gabriel Toffani - CEO at Adionics: "The New version represents a significant leap forward in promoting a truly circular economy for lithium-ion. The versatility, combined with the ability to process battery black mass, positions Adionics at the forefront of sustainable lithium production. By solving the challenge of lithium extraction, we're not just reducing waste - we're creating a sustainable cycle for one of the most critical components in modern energy storage."

Key features of the new Flionex® technology include:

• Versatility to extract lithium at early, mid, and late stages of the recycling process
• Extraction of 99% pure lithium suitable for immediate reuse in new batteries
• A liquid-to-liquid process that operates without acids
• Zero toxic by-product generation
• Elimination of overseas processing, reducing carbon footprint

The development comes at a critical time as the demand lithium in electric vehicles and renewable energy storage continues to grow. 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.

This innovation aligns with recent U.S. legislative efforts to strengthen the domestic battery supply chain and promote sustainable practices in the production and recycling of critical minerals.

Adionics' liquid-liquid extraction process demonstrated exceptional performance in recent tests, achieving lithium recoveries of up to 98% across a range of brine concentrations. This versatility, combined with the ability to process battery black mass, positions Adionics at the forefront of sustainable lithium production.
