Cobalt is a prized material for battery production, particularly in electric vehicles (EVs), but its geopolitical implications raise concerns. The Democratic Republic of the Congo (DRC) holds the majority of global cobalt reserves, which are often associated with human rights violations in mining practices, while a significant portion (72%) of cobalt refinement occurs in China. This situation has broader implications, as cobalt is also critical for the U.S. military, which relies on lithium-ion batteries for drones, and various components in aerospace applications.
Currently, the U.S. lacks any cobalt refining facilities, which heightens the vulnerability of domestic consumers reliant on this essential mineral. John Busbee, CEO of Xerion Advanced Battery Corp., has highlighted concerns over China’s influence, as recent moves by the country to restrict access to critical minerals have intensified urgency for alternative sourcing strategies.
In response to these challenges, Xerion has developed a novel method for producing highly purified cobalt using a combination of electricity and heat. This innovative technique plates metals onto electrodes, drawing them from a molten salt bath, enabling simultaneous production of battery materials and refined cobalt. Despite initial reluctance from established battery manufacturers to adopt this new method—given their substantial prior investments—Xerion remains optimistic.
With the intensifying global trade tensions, Xerion has pivoted its focus to cobalt. The company is inaugurating a pilot production facility in Dayton, Ohio, capable of generating five metric tons of cobalt. While this output may seem minimal in light of global demand, it aligns with the U.S. military’s more modest requirements for cobalt in aerospace alloys, which total approximately 5,000 to 10,000 metric tons.
Looking ahead, Xerion’s facility aims to scale up to an annual output of 2,000 metric tons of cobalt, positioning itself competitively with Chinese production at pilot scale. Busbee asserts confidence in the viability and cost-effectiveness of this strategy, suggesting that even at this early stage, Xerion’s operations might be on par with Chinese counterparts. Overall, the company hopes to address reliance on external cobalt sources while contributing to advancements in battery technology.
