The BMW Group has announced that it will source next-generation batteries for its electric vehicles from Samsung SDI and LG Energy Solution (LG Ensol). The two South Korean firms join China's CATL and EVE Energy to supply cells for BMW's sixth-generation (Gen6) high-voltage battery packs.

Samsung SDI has extended its 17-year partnership with the German carmaker by agreeing to supply 46-series cylindrical batteries for the Neue Klasse EV platform. BMW's Gen 6 packs will use two 46 mm diameter cylindrical cell formats: 4695 (95 mm height) and 46120 (120 mm height).

Compared to current-generation prismatic cells, these new cylindrical batteries offer 20% higher energy density, up to 30% longer driving range on a single charge, and around 30% faster charging speeds.

BMW is following a localization strategy, sourcing battery cells in close proximity to its vehicle assembly plants across Asia, Europe, and North America. It reduces shipping distances, stabilizes supply chains, and improves regional value creation.

To support this rollout, Samsung SDI is building a 46-series production line at its existing plant in Göd, Hungary, with commercial mass production targeted for 2028.
