Amprius Establishes Korea Battery Alliance to Expand Global Partnerships and Strengthen Supply Chain
Amprius Technologies, Inc. (“Amprius” or the “Company”) (NYSE: AMPX), a global leader in next-generation lithium-ion batteries powered by its proprietary Silicon Anode Platform, today announced the formation of the Amprius Korea Battery Alliance (“the Alliance”). This strategic initiative is designed to reinforce the company’s international presence, deepen collaboration with key industry partners, and diversify its expanding global manufacturing network, which now exceeds 2.0 GWh of total capacity worldwide.
The creation of the Alliance represents a major step forward in Amprius’ mission to commercialize high-performance silicon anode batteries and secure critical elements of its supply chain amid growing global demand for advanced energy storage solutions. By establishing a formal partnership ecosystem in South Korea—one of the world’s most advanced battery manufacturing hubs—Amprius is positioning itself at the center of a rapidly evolving global market for electric mobility and clean energy technologies.
Building on a Strong Foundation in Korea
Amprius is expanding upon its existing technical and manufacturing base in South Korea, where the company already collaborates with local partners on research, production, and equipment development. The newly launched Korea Battery Alliance brings together a diverse network of industry leaders across the country’s battery supply chain, including battery manufacturers, materials suppliers, component producers, and equipment makers, as well as members of Korea’s investment community.
Through these partnerships, Amprius intends to enhance both innovation and scalability in the development of silicon anode-based lithium-ion batteries. The Alliance’s members are already collaborating with Amprius in several key areas, including SiCore battery cell production, electrode materials innovation, and manufacturing equipment design and optimization.
Strengthening Global Supply Chain Resilience
As the electric vehicle (EV) and clean energy markets expand worldwide, access to reliable, high-quality battery components has become increasingly vital. The Amprius Korea Battery Alliance aims to secure critical links in the global supply chain by aligning Korea’s world-class manufacturing expertise with Amprius’ cutting-edge technology platform.
This alliance will also help Amprius mitigate potential supply risks, balance production capacity across regions, and accelerate time-to-market for new products. By cultivating long-term relationships with Korean partners, Amprius is reinforcing a supply network that supports both scalability and cost efficiency, key factors in meeting surging demand from customers in the EV, aerospace, and wearable electronics sectors.
“South Korea is home to some of the most advanced battery technologies and manufacturing capabilities in the world,” said Dr. Kang Sun, Chief Executive Officer of Amprius Technologies. “The establishment of the Amprius Korea Battery Alliance marks a critical step in expanding our global footprint and accelerating the commercialization of our high-performance silicon anode batteries. Through close collaboration with our Korean partners, we aim to enhance scalability, improve cost structure, and strengthen our ability to serve a growing international customer base.”
Empowering Members Through Collaboration
The Amprius Korea Battery Alliance is more than a supply chain initiative—it is designed as a platform for shared innovation. Alliance members will have access to Amprius’ technical expertise, joint business development opportunities, and advanced R&D support. By facilitating the exchange of knowledge and resources, the Alliance aims to accelerate the deployment of next-generation battery technologies across multiple industries.
Amprius plans to provide its Korean partners with direct access to its proprietary silicon anode cell technology, enabling collaboration on both pilot-scale and full-scale production projects. These efforts will be supported by the company’s expanding global infrastructure, which now includes research and manufacturing operations in the United States, China, and South Korea.
Advancing Silicon Anode Technology for a Greener Future
At the heart of Amprius’ strategy is its Silicon Anode Platform, a breakthrough in lithium-ion battery chemistry that enables energy densities significantly higher than those achieved by traditional graphite-based batteries. This technology has already demonstrated energy densities exceeding 500 Wh/kg, setting new performance benchmarks for lightweight, high-capacity batteries.
By combining this advanced technology with Korea’s renowned manufacturing precision and scale, Amprius and its partners aim to accelerate the transition to clean energy and electric mobility. The alliance is expected to play a vital role in supporting the next generation of electric vehicles, aviation technologies, and grid-scale storage systems that depend on superior energy efficiency and durability.
A Globally Integrated Ecosystem
The formation of the Korea Battery Alliance aligns with Amprius’ broader strategy to establish a globally integrated manufacturing ecosystem. The company is strategically linking its research and production sites across the U.S., China, and now South Korea, to create a seamless network that connects innovation, supply, and market access.
This international approach not only increases production flexibility but also allows Amprius to serve customers across continents more effectively. By distributing its production base and fostering regional partnerships, Amprius is reducing logistical bottlenecks and ensuring a more resilient and responsive supply chain in an increasingly competitive global battery market.
