Samsung's Cheonan factory is part of the company's advanced manufacturing network, playing a significant role in battery cell production, particularly for the electric vehicle (EV) industry. The plant is currently preparing to introduce a pilot production line for the 4680 battery cell, a key component for Tesla's electric vehicles. Samsung SDI has planned for initial production capacity at the Cheonan facility to reach around 1 GWh, with plans to scale this up to between 8 to 12 GWh in the future​
