America Finds Lithium-But China Still Controls the Chokepoint

Highlights

• USGS identified 2.3 million metric tons of economically recoverable lithium in Appalachia, enough to replace centuries of U.S. imports.
• China controls an estimated 70% of global lithium refining capacity, meaning the U.S. still depends on Chinese industrial systems to convert raw lithium into battery-grade materials.
• The U.S. operates only one active lithium mine producing roughly 1,000 metric tons annually versus China's approximately 62,000 metric tons plus dominant refining infrastructure.
• A CISES briefing warns that without refining investment, permitting reform, and industrial policy, Appalachian lithium may simply feed Chinese-controlled processing chains.
• The report highlights a critical Western misconception: resource ownership does not equal supply chain independence—refining and chemical processing are the true chokepoints.

A new briefing note by Erin Spellman (opens in a new tab) of the Centre for International Security and Economic Strategy (opens in a new tab) (CISES) argues that America’s newly announced Appalachian lithium discovery may be far less strategically transformative than headlines suggest. The May 2026 report, America’s Critical Minerals Problem: Why the Discovery of Lithium Is Not Leverage, explains that while the United States Geological Survey (USGS) identified an estimated 2.3 million metric tons of economically recoverable lithium—reportedly enough to replace centuries of current U.S. lithium imports—the far more consequential battle lies downstream in refining and processing, where China still controls an estimated 70% of global lithium refining capacity. In practical terms, America may possess more lithium underground, but China still largely controls the industrial systems that transform lithium into battery-grade chemicals essential for electric vehicles, military systems, AI infrastructure, consumer electronics, and grid-scale energy storage.

What the Report Actually Examined

The briefing is not a geological resource study, but rather a geopolitical and industrial policy analysis examining the strategic implications of the Appalachian lithium discovery. Spellman evaluates the issue through the lenses of supply chain dependency, sovereign debt constraints, industrial financing, permitting delays, and China’s vertically integrated critical minerals ecosystem. The report repeatedly emphasizes a central point often misunderstood in Western political discourse: mining alone does not create supply chain independence.

Refining, chemical conversion, metallization, precursor materials, and advanced manufacturing remain the true industrial chokepoints.

The report notes that the United States currently operates only one active lithium mine producing roughly 1,000 metric tons annually, compared to approximately 62,000 metric tons of Chinese production alongside Beijing’s dominant refining infrastructure.

The Strategic Warning Beneath the Headlines

Perhaps the report’s most important insight—and one Rare Earth Exchanges™ readers will immediately recognize—is that the West continues to confuse resource ownership with industrial control. China spent decades constructing integrated mine-to-battery ecosystems supported by state-backed financing, industrial policy, permitting speed, chemical processing expertise, and downstream customer qualification networks. Meanwhile, much of the West outsourced refining and advanced materials processing while assuming commodity markets alone would solve strategic dependencies.

Spellman warns that without aggressive investment in refining infrastructure, permitting reform, financing mechanisms, and coordinated industrial policy, Appalachian lithium could ultimately become little more than another upstream raw material feeding Chinese-controlled processing chains.

Limitations and Open Questions

The report is persuasive, but not exhaustive. It does not deeply examine emerging U.S. refining projects, direct lithium extraction (DLE) technologies, recycling advances, or allied processing partnerships involving countries such as Australia, Canada, Japan, and South Korea. Nor does it fully explore whether geopolitical shocks or national security pressures could accelerate Western industrial mobilization faster than current assumptions suggest.

Still, the paper’s central argument remains difficult to dismiss: discovering lithium is not the same thing as controlling the battery supply chain.
