Aqua Metals Achieves Milestone With 100% Recycled Nickel Cathode Material For Lithium-Ion Batteries; CAM Undergoing Evaluation By Tier-One Battery Manufacturer

Aqua Metals, Inc. (NASDAQ:AQMS), a pioneer in sustainable lithium-ion battery recycling, has worked with leading industry partners to successfully produce the first-ever cathode active material (CAM) made from 100% domestically sourced, recycled nickel. This achievement represents a critical step toward establishing a cleaner, more secure domestic battery supply chain in the U.S.

Using its proprietary AquaRefining™ process, Aqua Metals recovered high-purity nickel from spent lithium-ion batteries and battery manufacturing scrap. Aqua Metals refined that recycled nickel into battery-grade nickel nitrate, a key precursor in advanced cathode production. One of Aqua Metals' domestic CAM manufacturing partners then utilized an innovative, low-carbon process to convert the nickel nitrate material into battery-grade CAM. This CAM is currently undergoing evaluation by a tier-one lithium battery manufacturer under established qualification protocols, and initial testing was positive and the samples are progressing through the validation process.
