US Targets 1 Million Tons of Lithium Production by 2035, Says DoE

Department of Energy (DOE)

The US Department of Energy (DoE) projects that the country could produce 1 million metric tons (t) of battery-grade lithium by 2035. This output would be sufficient to meet domestic demand while allowing for exports to trading partners.

Scaling Up Domestic Lithium Production

The DoE's Loan Programs Office Director, Jigar Shah, emphasized the need to expand lithium extraction, processing, and recycling to support the growing lithium-ion battery industry. He noted that diverse lithium resources across multiple US regions could be unlocked using advanced technology and infrastructure investments.

The US plans to increase lithium supply through three key sources:

• Spodumene deposits in Charlotte, North Carolina, expected to produce 100,000-150,000 t/yr of lithium carbonate equivalent (LCE).
• Albemarle’s Kings Mountain mine is one of the most advanced spodumene projects, projected to yield 50,000 t/yr of LCE.

• Brine and clay resources in Nevada, California's Imperial Valley, and the Arkansas Smackover Formation, estimated to contribute 500,000-1 million t/yr of LCE.
• These resources have lower lithium concentrations than South American reserves, but direct lithium extraction (DLE) technology can help process them efficiently.
• Recycling of end-of-life EV batteries, which could reduce the need for new lithium extraction, supplying 50,000-100,000 t/yr of LCE by 2035.

Government Investment in Lithium Infrastructure

The Biden administration has significantly increased investments in US lithium production to accelerate the clean energy transition.

In September 2024, the DoE selected 25 projects across 14 states, committing over $3 billion to expand domestic lithium supply. Additionally, the Thacker Pass lithium project in Nevada, operated by Lithium Americas, received a $2.3 billion loan to build a 40,000 t/yr lithium carbonate facility.

In December 2024, the DoE also allocated $17 million to 14 critical mineral technology projects, reinforcing efforts to scale up lithium production.

Lithium’s Role in the US Energy Transition

According to the US Geological Survey, the US has 1.1 million tons of lithium reserves, compared to a global total of 28 million tons.

Shah highlighted that advancements in direct lithium extraction (DLE) could rapidly unlock large lithium resources, much like hydraulic fracturing transformed the oil and gas industry.

With global lithium demand rising, the US is positioning itself as a key player in the lithium supply chain, reducing dependence on foreign imports and strengthening the clean energy sector.
