6K lines up up to $250M US loan to build battery cathode plant on its AM powder process

6K, the maker of UniMelt-based metal powders for additive manufacturing, has a conditional offer of up to $250 million from the US Department of War. The money would build the PlusCAM plant in Jackson, Tennessee, which applies the same microwave plasma process to lithium-ion battery cathode. Nothing is paid out until government due diligence and a list of conditions are met.

Context UniMelt is 6K's microwave plasma process; for AM it turns feedstock into metal powder, and 6K says for cathode it replaces conventional precursor materials known as pCAM.

What is the loan for?

The commitment comes through the Office of Strategic Capital of the US Department of War and covers up to $250 million. 6K, based in North Andover, Massachusetts, would use it to construct PlusCAM in Jackson, Tennessee, a plant for cathode active material used in lithium-ion batteries. 6K says the facility would support more than 200 jobs and reduce reliance on cathode made abroad.

How does an AM powder process fit in?

6K Additive already uses UniMelt commercially to make metal powders for the US defence industrial base. In cathode production, 6K says the process skips conventional precursors and enables a closed-loop plant that turns metal or other alternative feedstocks into cathode with little waste. The company also says this removes dependence on raw materials from Foreign Entities of Concern.

What conditions apply?

The loan is not final. Government authorisations and appropriations must be in place, and the Department of War must finish its due diligence. 6K must meet financial, legal, technical and regulatory conditions. No funds flow before that.

What earlier funding exists?

In late 2025, 6K Energy received $1.9 million from the Defense Logistics Agency for a one-year project on single-crystal NMC721 cathode for defence batteries. Also in late 2025, the Export-Import Bank approved a $27.41 million loan to expand the Burgettstown, Pennsylvania powder plant, on top of an earlier $23.4 million Defense Production Act grant.

What it means

For AM buyers, this is mainly a signal about the powder supplier's financing, not a new product. Public defence money is flowing into 6K's UniMelt platform, which could support powder capacity, but the loan is conditional and the plant targets batteries, not AM. European manufacturers sourcing refractory or specialty powders should treat it as supplier context, not a change in availability or price.

Frequently asked questions

How much is the 6K loan and who offers it?

Up to $250 million, as a conditional commitment from the US Department of War through its Office of Strategic Capital.

Has 6K received the money?

No. Government authorisations, appropriations and due diligence, plus 6K's own conditions, must be completed before any funds are disbursed.

What will the Jackson plant make?

Cathode material for lithium-ion batteries, produced with the UniMelt plasma process that 6K Additive already uses for metal powders.
