Pentagon conditionally approves $250M loan for 6K to build US battery material factory

DoD Loan for Domestic Battery Production

6K, a North Andover, Massachusetts-based startup, announced conditional approval for a $250 million loan from the Department of Defense. This funding is designated for building a new factory in Tennessee focused on producing battery materials. The initiative aligns with the Pentagon's interest in increasing domestic manufacturing capabilities for critical components.

Reducing Supply Chain Dependence

The new factory will utilize 6K's proprietary microwave-powered process to create battery materials. This method aims to reduce the United States' reliance on Chinese suppliers for these essential components. The company states its process can be applied to various battery chemistries, including lithium iron phosphate (LFP).

6K's Manufacturing Technology

6K's manufacturing process involves using microwaves to heat metals into a plasma state, which are then deposited onto a surface. This technique reduces the number of steps typically required to produce cathode material, a key ingredient in batteries. The company has been developing this technology for 12 years.

Previous Funding Challenges and Delays

The company previously secured a $50 million grant from the Department of Energy in 2023 under the Bipartisan Infrastructure Law. However, this grant was later canceled, necessitating a reapplication process. The cancellation and uncertainties in the electric vehicle market led 6K to revise its original plans for the factory, which was initially slated to open in 2024.
