US-based silicon battery anode developer Amprius Technologies has formed a manufacturing partnership with lithium-ion battery developer Nanotech Energy to expand its production footprint from Asia into the US market.
Nanotech Energy is Amprius’ first US-based manufacturing partner and strengthens its ability to serve defense, aerospace, and other critical markets by providing secure, domestic production that meets stringent sourcing and compliance requirements. The partnership aligns with the recently updated National Defense Authorization Act (NDAA), according to Amprius.
The partnership establishes a US supply chain for Amprius’s customers including L3Harris Technologies, which delivers end-to-end technology solutions connecting the space, air, land, sea, and cyber domains in the interest of national security.
In recent months, Amprius and Nanotech have refined the design and manufacturing of the Amprius SA128 silicon-anode cell. The 21700 cylindrical cell has a capacity of 6.8 Ah and specific energy of 320 Wh/kg.
The contract manufacturing capacity from Nanotech increases Amprius’s global capacity beyond 2 GWh.
“Establishing a US manufacturing partner is essential to meeting the evolving requirements of our defense customers,” said Tom Stepien, CEO of Amprius. “Nanotech brings deep expertise in developing and manufacturing advanced lithium-ion cells. Their manufacturing skills and our industry-leading designs enable us to move quickly from development to production while maintaining the quality, security, and performance our customers expect.”
