Amprius Technologies, Inc. has entered into a contract manufacturing agreement with a leading South Korean battery producer to expand its global production footprint and meet growing demand for its silicon anode cells. Under the new arrangement, the Korean facility will produce Amprius SiCore® cells according to the company’s specifications, adding to its existing 1.8 GWh of contracted production capacity. Initial output will focus on a balanced SiCore cell designed for high-energy, high-power applications in advanced drones.
“This partnership reflects the next step in Amprius’ capital-light production scaling strategy,” said Dr. Kang Sun, CEO of Amprius Technologies. “By expanding our manufacturing footprint into new regions, we are strengthening our supply chain and positioning ourselves to serve global customers with greater speed and efficiency. This collaboration allows us to scale confidently while continuing to deliver the industry-leading performance for which Amprius is known.”
Expanding manufacturing into South Korea is expected to streamline logistics, reduce lead times, and enhance the company’s ability to compete in international markets. It also builds on Amprius’s strategy to diversify its production network, ensuring consistent cell availability as end users increasingly adopt high-performance silicon-based batteries. The collaboration is anticipated to accelerate the commercialization of Amprius’s SiCore platform and reinforce its position in next-generation battery technology.
Headquartered in Fremont, California, Amprius develops high-energy, high-power lithium-ion cells with the industry’s highest-known energy density. Its commercially available SiMaxx™ batteries achieve up to 450 Wh/kg and 1,150 Wh/L, with independent validation reaching 500 Wh/kg and 1,300 Wh/L. The company introduced the SiCore® platform in 2024 to broaden its addressable market. In addition to its in-house MWh-scale manufacturing facility, Amprius continues to secure contract capacity worldwide to fulfill accelerating demand.
