Amprius Grows Its Battery Partnership in Korea with Three New Contract Manufacturers

Amprius Technologies, Inc., a prominent player in next-generation lithium-ion batteries, has announced the growth of its Korea Battery Alliance after a successful launch event in Daejeon, South Korea.

The Alliance has now added three new contract manufacturers, joining a group of Korean companies that provide materials, components, and production equipment for lithium-ion batteries. This expansion increases Amprius’ global manufacturing network and gives the company direct access to Korea’s advanced battery production system, which helps Amprius grow in trusted countries.

One of the main goals of the Alliance is to meet the U.S. National Defense Authorization Act (NDAA) requirements. By expanding production in allied countries, Amprius is reinforcing its secure as well as compliant supply chain to support industries like defense, aerospace, and critical infrastructure.

With the new partners, Amprius’ contract manufacturing network now has over 2 GWh of global capacity. This will help the company meet growing demand in its key markets.

The launch event was attended by Alliance members, South Korean government officials, investors, industry experts, university researchers, and media. The event focused on coordinating production, working with suppliers, and setting short-term goals.

Executive Statement

According to Tom Stepien, President of Amprius Technologies, deepening their partnerships in Korea enables them to scale efficiently while delivering exactly what their customers require. The Alliance anchors Amprius within a world-class lithium-ion battery manufacturing base and allows them to accelerate SiCore® production within an NDAA-compliant framework.

According to Mayor Lee Jang-woo, South Korea is a global leader in advanced battery technology, and Amprius is at the forefront of next-generation silicon anode innovation. Expanding their partnerships in Daejeon reinforces the city’s standing as a center for energy and materials innovation, and drives new growth across the regional economy.
