Aqua Metals says nickel carbonate increasingly is in demand across multiple regions globally, where carbonate forms are high in value for battery and metallurgical applications. In particular, the company notes that nickel carbonate can be further processed into pure nickel metal for various applications or converted into nickel oxide, a critical input for the steel industry.

“Developing a high-purity nickel carbonate product as an additional battery material resource Aqua Metals can offer battery manufacturers is a testament to the power and flexibility of our technology,” says Ben Taecker, Aqua Metals’ chief operations and engineering officer. “Our team continues to find new ways to optimize recovery, reduce waste and respond to real-time market needs—all while maintaining our commitment to clean, low-impact processes.”

The company says the new product aligns with its broader strategy to scale the production of battery-grade lithium, nickel, cobalt and manganese materials with its patented technology. As it advances offtake discussions and project financing, the company says the introduction of nickel carbonate underscores its “momentum in building a robust, diversified domestic supply chain for critical minerals essential to the advanced energy economy.”
