Hyundai Motor Group and SK On to build battery cell plant in Georgia

Battery cells will go to Hyundai Mobis in Montgomery for assembly; then to Hyundai to power its EVs

Hyundai Motor Group and SK On plan to build an EV battery cell production plant in Bartow County, Georgia. Hyundai Motor Group and SK On each will have a 50% stake in the new battery cell plant, which is estimated to cost $5 billion to build.

Once operational in the second half of 2025, the battery cell plant is expected to have an annual production capacity of 35 GWh, which is sufficient to support the production of 300,000 EVs.

After the battery cells are built at the new plant, they will be shipped to Hyundai Mobis, in Montgomery, for assembly into battery modules. The battery modules will then be shipped to Hyundai Motor Manufacturing Alabama (HMMA), Kia Georgia and Hyundai Motor Group Metaplant Atlanta.

Hyundai Motor Manufacturing Alabama started producing the EV Genesis earlier this year. The Electrified GV70 is the brand’s third all-electric model. The start of production was made possible by a $300 million infrastructure expansion and upgrade at Hyundai’s Montgomery plant in 2022.

Hyundai Mobis announced in 2022 that it would invest $205 million to develop an EV battery module plant to support both Hyundai Motor Manufacturing Alabama and Kia Georgia. Hyundai Mobis, which currently employs about 1,100 workers in Montgomery making front and rear chassis and cockpit modules for HMMA, will add about 400 employees to make the new battery modules.

“As the EV market continues to grow, having a strong production capacity will be key in allowing Hyundai Mobis to see continued growth in the market,” H.S. Oh, vice president of electric powertrain business of Korean-based parent company Hyundai Mobis, told Business Alabama earlier this year.
