Amprius Scales Global Battery Manufacturing Network: Korea Alliance Adds 2 GWh Capacity with Three New Partners
Strategic Expansion Secures Advanced Battery Supply for Defense and Aerospace
Amprius Technologies has significantly boosted its manufacturing capacity and global reach by welcoming three new contract manufacturers into the Amprius Korea Battery Alliance. This expansion—unveiled at a well-attended event in Daejeon, South Korea—positions Amprius with more than 2 GWh of contract manufacturing capacity, strengthening its ability to meet surging demand for next-generation silicon anode batteries across defense, aerospace, and critical infrastructure markets.
NDAA Compliance Strengthens Global Supply Chain Security
A major driver behind this move is compliance with the U.S. National Defense Authorization Act (NDAA), which prioritizes trusted supply networks for defense-related products. By forging alliances with reputable South Korean firms across the lithium-ion battery value chain, Amprius secures both the advanced technology and compliant manufacturing partners necessary to deliver its industry-leading SiCore® batteries—products that boast up to 450 Wh/kg and 1,150 Wh/L energy densities.
Access to Korea’s Advanced Battery Ecosystem Accelerates Innovation
The alliance with leading Korean contract manufacturers offers Amprius direct entry into one of the world’s foremost battery innovation hubs. This collaboration facilitates rapid scale-up and execution, with new partners contributing materials, components, and specialized production equipment. The ecosystem integration ensures that Amprius can efficiently ramp up SiCore® production, supporting its strategic push into high-growth markets and reinforcing its leadership in silicon anode battery technology.

New Manufacturing Partnerships Lay Foundation for Market Expansion
By anchoring itself in South Korea, Amprius accelerates not just the volume, but the security and flexibility of its production pipeline. Local officials in Daejeon have highlighted the regional economic and innovation benefits, further rooting Amprius within a globally recognized center for advanced energy technologies. The result: Amprius is well positioned to seize growth opportunities while maintaining compliance and security standards critical to its core customer segments.
Takeaway: Global Collaboration Puts Amprius on the Fast Track
For investors and industry observers, Amprius’ expanded Korea Battery Alliance signals an intentional move to capture rising global demand and align with strict defense and aerospace requirements. While risks related to execution and competition remain—as with any forward-looking venture—the increased capacity and supply chain fortification suggest Amprius is taking the steps necessary to remain at the forefront of high-performance battery manufacturing.
