6K Additive partners with CRG Defense on seven-year domestic battery supply deal for U.S. defense

6K Energy, the battery materials arm of 6K Additive, has signed a seven-year agreement with CRG Defense to supply single-crystal NMC811 cathode active materials (CAM) for U.S. defense and mission-critical battery applications. The deal covers initial supply from 6K Energy's North Andover, Massachusetts facility, with additional capacity from its PlusCAM plant in Jackson, Tennessee expected online in early 2028. A structured Quarterly Purchase Plan will ensure consistent material flow for CRG Defense's next-generation unmanned aerial systems (UAS) and other defense platforms. The partnership is explicitly designed to meet new federal mandates, including the FCC's December 2025 ban on foreign-produced UAS components and Section 842 of the FY 2026 NDAA, which prohibits Department of Defense procurement of batteries from foreign entities of concern.

This agreement sits at the intersection of two powerful AMPulse patterns: the defense vertical's politically accelerated 2025-26 wave and the broader Chinese localization arc in reverse. The NDAA §842 provision, effective December 2026, creates a structural market redefinition that directly benefits domestic CAM producers like 6K Energy. The deal also demonstrates how additive manufacturing's materials expertise — 6K's UniMelt microwave plasma platform, originally developed for metal powder production — is being leveraged to solve battery supply chain vulnerabilities. This is not a printer sale or a service bureau contract; it is a materials-level play that locks in demand through qualification and regulatory compliance, mirroring the IP lock-in grind pattern but with policy as the moat. The defense vertical, historically slow to adopt AM for structural parts, is now driving rapid adoption in energy storage where qualification cycles are shorter and the national security imperative is explicit.

For 6K Additive, this partnership validates its strategy of extending UniMelt technology beyond metal powders into battery materials, a diversification that reduces dependence on the volatile metal AM powder market. The real execution risk lies in scaling the PlusCAM facility on time and to spec — 2028 is distant in defense procurement timelines, and any delay could push CRG Defense toward alternative domestic suppliers. For the broader AM industry, this deal reinforces a key lesson: the most durable near-term revenue in defense may come not from printing parts, but from supplying the materials that make those parts — and their power sources — NDAA-compliant.
