Aqua Metals nickel carbonate supply deal strengthens US battery metals recycling

Aqua Metals

Aqua Metals nickel carbonate supply agreement with Westwin Elements marks a key step for US battery metals recycling. The US recycler will provide 500-1,000 t/yr of recycled nickel carbonate to Westwin under a long-term pathway. The Aqua Metals nickel carbonate supply deal is expected to be worth about $12mn/yr at today’s nickel prices. Both partners will depend on new commercial plants scheduled to come online before deliveries begin in 2027.

Nickel carbonate offtake anchors new US refining capacity

The agreement gives Westwin an early anchor for battery-grade feedstock from domestic recycling rather than primary mining. Aqua Metals nickel carbonate supply will support Westwin’s planned nickel refining operations, which aim to produce high-purity material for battery and specialty alloy markets. As a result, the deal helps de-risk Westwin’s project pipeline by pre-qualifying a secure source of recycled nickel.

Aqua Metals has already passed Westwin’s production testing and qualification process for battery-grade nickel carbonate. This performance validation is critical because cathode and precursor producers maintain strict impurity thresholds. Therefore, the Aqua Metals nickel carbonate supply arrangement signals technical confidence in the company’s hydrometallurgical recycling flowsheet.

Recycling gains ground in critical minerals strategy

The partnership reflects a broader shift toward closed-loop battery metals supply chains in North America. Policymakers increasingly view recycled nickel as a strategic complement to mined supply, especially for EV and stationary storage markets. Meanwhile, investors favor projects that combine ESG benefits with exposure to high-value nickel chemicals.

By locking in an offtake pathway ahead of full-scale commissioning, both firms position themselves for an expected demand upturn toward 2027. If execution stays on track, the collaboration could become a reference model for similar nickel, cobalt and lithium recycling deals.

The Metalnomist Commentary

This agreement underscores how offtake-linked recycling hubs are becoming central to North America’s battery raw materials strategy. The commercial validation of Aqua Metals’ nickel carbonate also highlights the maturing economics of hydrometallurgical recycling versus imported intermediates. Market participants should watch how quickly the partners convert this non-binding framework into bankable, long-term contracts.
