Samsung SDI Secures Major LFP Battery Supply Deal in the U.S.

Samsung SDI announced that its U.S. subsidiary, Samsung SDI America, has signed a multiyear agreement to supply lithium iron phosphate (LFP) batteries to a major U.S.-based energy infrastructure company. The deal, valued at more than 2 trillion won (approximately $1.36 billion), marks a significant step in the company’s strategy to expand its footprint in the fast-growing energy storage system (ESS) market. Deliveries under the contract will begin in 2027 and continue for three years, reinforcing Samsung SDI’s long-term commitment to supporting clean energy solutions in the United States.

Although the customer’s identity was not disclosed, Samsung SDI described the partner as a leading developer and operator of energy infrastructure. The announcement sparked strong investor interest, with Samsung SDI shares climbing as much as 6.1% in morning trading, even as the KOSPI index slipped 0.1%. The surge reflects market confidence in the rising demand for ESS batteries, especially as global data centers, renewable energy projects, and grid stabilization efforts require more efficient and reliable storage solutions.

The LFP batteries involved in the contract will be produced using converted prismatic cell production lines at Samsung SDI’s U.S. facility. This shift aligns with the company’s broader strategy to adapt its manufacturing capabilities in response to evolving market conditions, including the transition away from certain U.S. subsidies for electric vehicle batteries. By repurposing EV battery production equipment for ESS applications, Samsung SDI aims to strengthen its competitiveness and capture new opportunities in the energy storage sector.

Samsung SDI, which already operates a joint venture EV battery plant with Stellantis in the United States, emphasized that ESS batteries share similar chemistry with automotive batteries, making the production transition efficient. As demand for renewable energy storage continues to grow, the company is positioning itself as a key supplier for next-generation power infrastructure.
