Batteries are everywhere, even on the battlefield, which also explains why the Pentagon has recently become interested in expanding its domestic manufacturing capabilities.
A startup company based in North Andover, Massachusetts, which was founded 12 years ago, announced on Thursday that it has received a conditional loan of $250 million from the U.S. Department of Defense. The company will use this funds to build a factory in Tennessee. This factory will employ a unique microwave-driven process to produce battery materials that do not rely on Chinese suppliers.
The company previously received a grant of $50 million from the Department of Energy under the Bipartisan Infrastructure Act, but this grant for 2023 was later cancelled during the Trump administration's chaotic cleanup of awards from the Biden era, forcing 6K to reapply.
Initially, this factory was scheduled to start production in 2024, but the cancellation of funding and the uncertainties in the electric vehicle market forced the company to adjust its plans.
The manufacturing process for 6K uses microwaves to heat metal into plasma, which is then deposited onto a surface, thereby reducing the number of steps required to produce the cathode material. The cathode material is a key component of a battery. The company stated that this process can be applied to various types of batteries, including lithium iron phosphate ( LFP ).
