On the 22nd, Samsung SDI and KGM signed a memorandum of understanding (MOU) for the development and commercialization of next-generation electric vehicle battery packs at KG Tower in Jung-gu, Seoul. The event was attended by Choi Ikgyu, Vice President and Head of the Small Business Division at Samsung SDI, and Cho Han-jae, Vice President and Head of Marketing at Samsung SDI, as well as Kwak Junghyun, President and Head of Business Strategy Division at KGM, and Kwon Yongil, Executive Vice President and Head of Development and Production Division at KGM.

Under this agreement, the two companies will jointly develop battery pack technology using Samsung SDI's 46mm cylindrical battery cells, while also engaging in technical and work exchanges for the development of next-generation battery packs. The battery packs developed through this collaboration are expected to be installed in KGM's future next-generation electric vehicles.

In addition, both companies agreed to establish a strategic partnership through mutual cooperation, including the formulation of mid- to long-term global battery market strategies, information exchange, and joint research and development (R&D).

Samsung SDI's 46mm cylindrical batteries offer both long driving range and fast charging speeds thanks to their high energy density, and can deliver stable performance in various driving environments due to enhanced safety and durability. In particular, the use of high-capacity high-nickel nickel-cobalt-aluminum (NCA) cathode materials and patented silicon-carbon composite (SCN) anode materials significantly reduces swelling and greatly extends battery lifespan.

The adoption of a tabless structure lowers internal resistance and optimizes current flow, thereby enhancing high output and fast charging performance. In addition, improvements in heat dissipation structure and advanced manufacturing processes have further secured safety and quality reliability.

A Samsung SDI representative stated, "This business agreement once again recognizes the differentiated technological competitiveness of our 46mm cylindrical batteries in the domestic and global electric vehicle markets," adding, "We will further strengthen our technological leadership in the next-generation global battery industry."
