Samsung SDI and KG Mobility forge strategic EV battery pack partnership
News, 24 December 2025
Samsung SDI and South Korean automaker KG Mobility (KGM) have officially agreed to jointly develop next-generation electric vehicle (EV) battery pack technology, marking a strategic collaboration as the global EV market heats up. The two companies signed a Memorandum of Understanding (MOU) on December 22 in Seoul, sealing plans to co-develop advanced battery packs built around Samsung SDI’s 46-series cylindrical battery cells.
The focus of this partnership is to design, test and ultimately commercialize high-performance battery packs that are expected to be used in future KGM electric vehicles. Samsung SDI’s 46-series cylindrical cells are engineered for high energy density, enabling longer driving range and faster charging, while also delivering improved safety and durability through enhanced materials and manufacturing processes. These batteries feature high-nickel NCA cathode chemistry and advanced Silicon Carbon Nanocomposite (SCN) anodes that help reduce swelling and extend lifespan key advantages for next-generation EV applications.
Beyond the technical development, the deal also lays the foundation for a deeper, long-term strategic alliance. Both firms plan to exchange insights on global battery market trends, pursue joint research and development, and align on broader electrification strategies. Executives from both Samsung SDI and KGM attended the signing ceremony, emphasizing the collaboration’s importance in strengthening competitiveness amid intensifying EV battery innovation worldwide.
For KGM, this partnership boosts its capabilities in EV battery engineering as it accelerates its transition toward electrified vehicle lineups. For Samsung SDI, the agreement underscores its commitment to expanding advanced battery technologies beyond traditional cell supply moving into integrated pack solutions that meet evolving automaker demands.
This development represents a meaningful step in South Korea’s EV supply chain evolution and highlights how battery makers and automakers are deepening ties to drive next-generation electric mobility forward.
