Defense Can Keep U.S. Battery Startups Alive—but It Cannot Replace EV Scale

U.S. battery startups are finding a second route to survival as the automotive market becomes less predictable: defense. Military systems need reliable batteries and secure access to materials, creating opportunities for advanced anodes, lithium processing, recycling, and other technologies that might otherwise struggle to reach commercial scale.

But defense is a bridge, not a substitute for electric vehicles. The U.S. Defense Logistics Agency procures about $200 million in batteries annually, according to the agency, while automotive manufacturing remains the far larger potential market. 31

Why defense matters to battery companies

Batteries are not limited to electric cars. They support a wide range of military equipment, including drones, radios, aircraft, and other systems that require dependable power in demanding conditions. The Department of Energy’s national battery strategy treats secure materials and domestic processing as priorities for both commercial and defense applications. 18

That gives startups an important opening. A military customer may value performance, reliability, safety, and supply assurance even when a technology is not yet the cheapest option for mass-market vehicles. Defense-related contracts, testing, and government-backed projects can help companies demonstrate their technology, maintain pilot production, and build an industrial base while automotive customers delay or reduce near-term commitments.

The opportunity is broader than selling finished batteries. The most strategically important projects may involve the materials and manufacturing infrastructure that every battery market depends on.

What the DOE’s $500 million is actually funding

The Department of Energy awarded $500 million across seven projects to expand domestic critical-mineral processing, battery-material production, manufacturing, and recycling. 712

Several awards illustrate the policy’s focus on supply-chain bottlenecks:

• Coreshell: $50 million to expand manufacturing of its metallurgical-silicon anode material. 7
• Lilac Solutions: $100 million for a planned direct-lithium-extraction and refining facility at Utah’s Great Salt Lake. The project is expected to open by 2028 and target 5,000 metric tons of lithium carbonate per year, according to reporting on the award. 4
• Nth Cycle: $100 million for black-mass processing to recover battery materials, including lithium and nickel compounds. 12

These are not simply procurement awards for military batteries. They support upstream and midstream capabilities: extracting and refining lithium, producing advanced anode materials, and recovering valuable inputs from used batteries. Those capabilities can serve both defense programs and civilian battery manufacturing.

The national-security rationale

The administration’s stated logic is supply-chain resilience: reducing reliance on foreign sources, strengthening national security, and expanding domestic production of critical minerals and battery materials. 74

That rationale reflects a basic vulnerability. A country can assemble battery packs domestically and still depend on overseas suppliers for refined lithium, specialty materials, recycling inputs, or other components. The DOE’s battery blueprint therefore links secure raw materials and processing with domestic electrode, cell, and pack manufacturing. 18

For defense planners, the issue is not only price. Dependence on foreign processing can create risks for continuity of supply, surge capacity, and access to specialized technologies. Supporting domestic battery companies can thus be framed as an industrial-readiness measure as well as an energy or climate policy.

Why defense cannot replace the EV market

The defense market is strategically important but comparatively small. The Defense Logistics Agency says it procures about $200 million in batteries each year. 31 That demand can support specialized products and help promising technologies survive, but it is not large enough by itself to drive the production volumes, supplier density, and cost reductions associated with mass-market vehicles.

Automotive production remains important because scale changes the economics of batteries. Larger factories can spread equipment and engineering costs across more units, while high-volume customers create pressure to improve yield, durability, and price. Defense programs may help a startup reach the next technical milestone; automotive demand is more likely to determine whether that technology becomes a broad manufacturing platform.

This is why a defense pivot should not be read as proof that battery startups have abandoned electric vehicles. It is better understood as a diversification strategy: use national-security demand and public funding to preserve capabilities until civilian demand strengthens or becomes clearer.

The policy contradiction

The grant round also exposes a tension in U.S. battery policy. The One Big Beautiful Bill was described in the supplied reporting as eliminating battery and EV incentives, while the administration continues to fund domestic mineral and battery projects on national-security grounds. 134

Those positions are not identical. A government can oppose consumer EV subsidies while supporting domestic production of materials considered strategically important. But the industrial base is interconnected. Mines, refineries, recyclers, anode and cathode suppliers, cell manufacturers, engineers, and specialized equipment makers can serve both civilian and military customers.

That means weakening the EV ecosystem may also make it harder to build a resilient defense battery ecosystem. The DOE grants can offset some of that pressure, but they do not remove the need for sustained private investment and reliable commercial demand.

What to watch next

The grants are best viewed as a policy backstop rather than a full reversal of the administration’s broader EV position. Their impact will depend on whether recipients can execute projects on schedule, reach commercial quality and output, attract private capital, and connect with customers beyond government programs.

The central takeaway is straightforward: defense gives U.S. battery startups a valuable lifeline because national security can justify paying for domestic capability before it is fully cost-competitive. Yet the long-term test remains civilian scale. If automotive demand and investment weaken for too long, defense funding may preserve strategically important niches without creating the large, low-cost battery industry the United States ultimately needs.
