Pentagon Proposes $250M Loan to Battery Startup for U.S. Manufacturing Facility

The presence of batteries in various sectors has prompted the Pentagon to focus on boosting domestic production capabilities.
The Massachusetts-based startup 6K, established 12 years ago in North Andover, announced on Thursday that it has received preliminary approval for a $250 million loan from the Department of Defense to construct a factory in Tennessee. This facility will utilize an innovative microwave-powered technique to manufacture battery materials independent of Chinese suppliers.
Previously, the company had obtained a $50 million grant from the Department of Energy through the Bipartisan Infrastructure Law. However, this grant was rescinded by the Trump administration amid a sweeping review of Biden-era funding, compelling 6K to reapply.
Initially expected to launch in 2024, the factory’s opening was delayed due to the grant cancellation and ongoing fluctuations in the electric vehicle market, prompting the company to revise its plans.
6K’s manufacturing method employs microwaves to transform metals into a plasma state, which is then deposited onto surfaces. This approach minimizes the number of steps needed to create cathode materials, essential components of batteries. The company claims that this technique is versatile enough to cater to various types of batteries, including lithium iron phosphate (LFP).
