US Department of Defense seeks to buy up to $300M of lithium for strategic stockpile
The Pentagon's first large-scale lithium procurement signals a new era for critical mineral supply chains and the broader energy transition.
The US Department of Defense is making its biggest bet yet on lithium. The Defense Logistics Agency has posted a solicitation for up to 16,167 metric tons of battery-grade lithium carbonate, with a contract ceiling of $300 million over five years.
It marks the first time the US government has pursued large-scale strategic stockpiling of lithium under the National Defense Stockpile.
What the Pentagon is actually buying
The solicitation, numbered SP8000-26-R-0021, targets approximately 16,167 metric tons of battery-grade lithium carbonate. That works out to roughly 35.6 million pounds of the stuff over a five-year contract period.
The contract has a guaranteed minimum of just $1 million, with the $300 million figure representing the ceiling. Bids are due by July 17, 2026, and the DoD will use a lowest-price technically acceptable evaluation model.
This isn’t the Pentagon’s first foray into lithium supply chain investment. In September 2023, the DoD awarded $90 million to Albemarle to boost domestic lithium production at the company’s Kings Mountain facility. A smaller request for information was issued in March 2026 for approximately 550 metric tons, essentially a test run before this much larger procurement.
The initiative falls under broader Congressional actions embedded in the FY2024 National Defense Authorization Act, which expanded the government’s authority to pursue multi-year contracts for critical minerals. Lithium-ion batteries now power everything from weapons platforms to portable military equipment, making reliable supply a matter of national security rather than just industrial convenience.
Why this matters beyond defense contracts
The move explicitly aims to reduce US reliance on foreign entities that control lithium resources. China dominates global lithium processing, refining roughly 60-70% of the world’s supply depending on how you measure it.
That said, scale matters. The 16,167 metric tons the DoD wants to acquire is relatively modest compared to global lithium carbonate production, which runs into the hundreds of thousands of tons annually.
The Albemarle precedent, a $90 million award specifically for US production capacity, suggests the DoD is willing to pay a premium for supply chain security.
