Aqua Metals has signed a multi‑year supply agreement (MSA) with 6K Energy, marking a key commercial step for its AquaRefining™ technology as it moves from pilot scale toward wider market deployment.
The deal sets out a framework for supplying battery‑grade nickel metal and lithium carbonate produced at Aqua Metals’ low‑carbon recycling facilities.
The agreement runs for three years and includes aligned product specifications, qualification processes and index‑linked pricing. 6K Energy will have the option to purchase materials at rates tied to London Metal Exchange benchmarks. Expected volumes could reach tens of millions of dollars annually once both companies complete their planned facility expansions.
AquaRefining™ is positioned as a cleaner alternative to conventional hydrometallurgical recycling, with the company reporting a 98% cut in greenhouse gas emissions and notable cost savings. The process avoids hydrogen peroxide and sodium hydroxide, regenerates sulphuric acid and produces no sodium sulphate waste.
Steve Cotton, President and CEO, said, “This agreement represents an important step in Aqua Metals’ transition from technology validation to customer-aligned commercialization.” 6K Energy President Saurabh Ullal added: “A reliable supply of high-purity, compliant battery materials is essential to scaling cathode manufacturing in the United States.”
The MSA also allows for future collaboration, including potential tolling of lithium‑ion black mass, supporting Aqua Metals’ aim to refine a range of battery chemistries as domestic demand grows.
