Samsung SDI has signed a memorandum of understanding (MOU) with South Korean automaker KG Mobility (KGM) to jointly develop battery pack technologies for EVs.

The companies will focus on battery pack technologies using Samsung SDI’s 46-series cylindrical battery cells, while expanding their collaboration on technologies to advance next-generation battery pack development.

The packs that the two companies develop through the partnership are expected to be used in KGM’s EVs in the future. The partners also plan to exchange insights into mid-to long-term global battery market strategies and pursue joint R&D efforts.

Samsung SDI’s 46-series cylindrical battery, which it started producing in 2025, offers high energy density, enabling extended driving range and fast charging capabilities, according to the company. Enhanced safety and durability deliver reliable performance under diverse driving conditions.

The battery features high-capacity nickel cobalt aluminum (NCA) cathodes and Samsung SDI’s silicon carbon nanocomposite (SCN) anodes, which are designed to reduce swelling while extending battery lifespan. A tabless design reduces internal resistance and optimizes current flow, enhancing high-power output and fast charging performance.
