Problem
Automotive manufacturers, renewable‑energy developers, and industrial users face limited access to high‑energy‑density, safe, and cost‑effective battery solutions, while supply chains for key materials such as lithium‑iron‑phosphate cathodes remain concentrated in a few regions.
Solution
Samsung SDI addresses this gap by designing, manufacturing, and supplying a diversified portfolio of lithium‑ion batteries and electronic‑material products for electric‑vehicle (EV) powertrains, grid‑scale energy‑storage systems (ESS), and high‑performance industrial applications. The company leverages proprietary cell architectures—including high‑nickel NCM, prismatic LFP, tabless cylindrical, and emerging all‑solid‑state designs—to deliver higher energy density, longer cycle life, and enhanced safety. Integrated safety technologies such as No Thermal Propagation (No TP) and Enhanced Direct Injection (EDI) mitigate thermal runaway risks. Samsung SDI also secures domestic cathode‑material supply through long‑term agreements, reducing dependence on external sources and ensuring stable production capacity in key markets like the United States. By combining advanced R&D, large‑scale manufacturing, and strategic supply contracts, the firm provides reliable, high‑value battery and material solutions that meet the performance and regulatory demands of its customers.
Target Audience
