Amprius Technologies, Inc. has entered into a contract manufacturing agreement with a leading South Korean battery producer to expand its global production capacity for silicon-anode lithium-ion cells. Under the arrangement, the South Korean partner will produce balanced SiCore® cells designed for high-energy and high-power applications, with the initial focus on advanced drone systems.
The collaboration aligns with Amprius’ capital-light strategy for scaling production and aims to bolster supply chain resilience. The South Korean facility will manufacture SiCore cells to Amprius’ specifications, supporting both current products and next-generation battery platforms. These cells are optimized for demanding markets including aerospace, defense, and electric mobility.
Amprius currently holds 1.8 GWh of contracted manufacturing capacity. The addition of the South Korean partner increases that footprint, enabling the company to meet growing international demand and accelerate delivery timelines by streamlining logistics. The expanded capacity is expected to help Amprius compete more effectively in key markets and respond to customer requirements with greater speed and flexibility.
“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.”
Amprius’ SiCore technology builds on its commercially available SiMaxx™ cells, which deliver up to 450 Wh/kg and 1,150 Wh/L. The company’s headquarters in Fremont, California, houses an R&D laboratory and a MWh-scale facility for silicon-anode and cell fabrication. To support customer demand, Amprius has established multiple contract manufacturing agreements, now representing more than 1.8 GWh of capacity worldwide.
By leveraging this new partnership, Amprius aims to accelerate the commercialization of high-performance silicon-anode batteries and pave the way for next-generation electric mobility and energy storage solutions.
