South Korean battery maker Samsung SDI is reportedly negotiating with Tesla to supply energy storage system (ESS) batteries in a deal that could exceed ₩3 trillion (approx. US$2.2 billion), according to Reuters. The potential agreement would support Tesla’s rapidly growing energy storage business, including products like Powerwall, Powerpack, and Megapack.
Strengthening Tesla’s Renewable Energy Supply Chain
The partnership, if finalized, would make Samsung SDI a core supplier in Tesla’s global energy ecosystem, joining existing battery partners such as Panasonic, LG Energy Solution, and CATL. By diversifying supply sources beyond China, Tesla aims to secure a more resilient supply chain for critical components amid geopolitical tensions.
Samsung SDI specializes in high-density, long-life lithium-ion batteries used in electric vehicles and industrial energy systems. The company has recently expanded its manufacturing footprint in the United States and Europe, aligning with surging global demand for clean energy solutions.
Market Implications
Industry analysts suggest that a finalized deal could deepen collaboration between Samsung SDI and Tesla, potentially reshaping competition in the global energy storage market, which is projected to exceed US$400 billion by 2030. The agreement would also mark a significant milestone for Samsung SDI, reinforcing its role in the accelerating renewable energy transition.
