The US military is putting money behind domestic battery materials. Battery startup 6K said it has won conditional approval for a $250 million loan from the Department of Defense to build a factory in Tennessee, according to TechCrunch, Defense Daily and Dealroom. The announcement was made on Thursday, November 5.
The deal. The loan commitment comes from the Pentagon’s Office of Strategic Capital, which other coverage says signed a $250 million conditional commitment with 6K for a facility in Jackson, Tennessee. The reports use different names for the department, with TechCrunch saying Department of Defense and the company and other outlets saying Department of War. The commitment is conditional on a matching investment from 6K and completion of financial and other due diligence, and the office is not taking an equity stake, according to the same coverage. The funds are expected to mobilize another $250 million in private capital.
What the factory would make. The plant would use a microwave-powered process to make battery materials that do not rely on Chinese suppliers, according to TechCrunch. The company’s process heats metals into a plasma and deposits them onto a surface, which it says cuts the steps needed to make cathode material. Other coverage describes finished nickel-manganese-cobalt cathode powders, while TechCrunch says the process works for several battery types, including lithium iron phosphate, so the exact product mix is not fully clear.
Why the domestic angle. Other reports say the US produces less than 1% of its nickel-manganese-cobalt cathode needs at home, a gap the Pentagon office blames on foreign price flooding. TechCrunch opens by noting that batteries are everywhere, even on the battlefield, which is the reason the defense department is involved.
The company’s earlier setback. 6K, a 12-year-old startup based in North Andover, Massachusetts, previously received a $50 million grant from the Department of Energy under the Bipartisan Infrastructure Law in 2023. The Trump administration canceled that grant in a sweep of Biden-era awards, forcing 6K to reapply, according to TechCrunch. The factory was originally due to open in 2024, and the cancellation and uncertainty in the electric vehicle market made the company rework its plans.
What is not stated. TechCrunch does not give the loan’s interest rate or repayment terms, the factory’s cost, capacity or job count, or a new opening date. There is no direct quote from 6K or the Defense Department in the article. The conditional nature of the loan means it is not final.
Why it matters. The Pentagon’s lending arm has been moving into battery supply chains, and other coverage points to a $1.4 billion conditional commitment to Sila Nanotechnologies in August. For the US and its allies, domestic cathode production reduces dependence on foreign suppliers for materials used in vehicles, grid storage and military equipment. For battery startups, government loans can fill a gap left by cancelled grants.
What to watch. Look for the final loan terms, the factory’s opening date and capacity, whether 6K meets the matching investment condition, and further Pentagon loans in the sector.
