Samsung is taking a major step toward the future of electric vehicle (EV) technology. Its subsidiary, Samsung SDI, has partnered with Korean automaker KG Mobility (KGM) to develop 46-series cylindrical battery packs for next-generation EVs. This collaboration combines Samsung’s battery expertise with KGM’s automotive experience.

Samsung and KG Mobility collaborate to advance EV Battery technology

For this effort, Samsung SDI and KG Mobility have recently signed a Memorandum of Understanding (MOU). During the signing ceremony, several executives from both companies were present. Samsung SDI’s executive team includes Ick Kyu Choi, Head of Mobile & Power Battery Business, and Han Jae Cho, Head of Marketing. From KG Mobility, Jeong Hyun Kwak, Chief Strategy Officer, and Yong Il Kwon, General Headquarters Director, took part in the ceremony.

The two companies will jointly develop battery packs using Samsung SDI’s 46-series cylindrical cells. These cells deliver high energy density for longer driving ranges and fast-charging capabilities. The batteries also focus on enhanced safety and durability for a reliable performance in various driving conditions.

The 46-series cells feature high-nickel NCA cathodes and Silicon Carbon Nanocomposite (SCN) anodes. This helps reduce swelling during charging and increases the battery’s lifespan. Furthermore, thanks to its tabless design, it minimizes internal resistance, optimizing high-power output and enabling faster charging. Likewise, advanced thermal management and manufacturing processes further improve safety and overall quality.

The batteries (developed through this collaboration) may power KGM’s next-generation electric vehicles. Moreover, the two companies plan to exchange insights on the global battery market and cooperate on joint R&D efforts. “This partnership once again proved the differentiated technological competitiveness of our 46-series cylindrical batteries in both Korean and global EV markets,” said a Samsung SDI official. “We will continue to strengthen our technology leadership in the next-generation global battery industry.”

Meanwhile, Samsung recently secured a $1.4 billion major deal with a US client to supply lithium iron phosphate (LFP) battery cells for energy storage systems.
