General Motors and Samsung SDI are expected to announce as early as Tuesday that they plan to build a new joint venture battery manufacturing plant in the United States, sources told Reuters.

Reuters reported in January that GM and LG Energy Solution would not move forward with a fourth U.S. battery manufacturing plant. GM and LG Energy are building a $2.6 billion plant in Michigan, set to open in 2024, one of three joint venture Ultium Cells LLC plants.

The new GM Samsung SDI plant is expected to cost more than the Michigan battery plant, the sources said, but no location will be immediately announced. GM and Samsung SDI did not comment.

In August, GM and LG Energy's joint venture said it was considering a site in New Carlisle, Indiana, for a fourth U.S. battery plant. In January, Reuters reported that GM and a new partner could still pick that Indiana site for a battery plant.

GM said last year it expects to build 400,000 EVs in North America from 2022 through mid-2024 and increase capacity to 1 million units annually in North America in 2025. Sources said GM is considering whether it will eventually need at least two additional EV plants to meet future EV demand.

South Korean media reported the potential GM Samsung SDI announcement in early March.

In May 2022, Stellantis NV and Samsung SDI announced they would invest more than $2.5 billion to build a new joint venture battery plant in Kokomo, Indiana. Stellantis and LG Energy said in 2022 they would invest $4.1 billion for a joint venture battery plant in Canada.

In 2022, U.S. President Joe Biden at a visit to Samsung in South Korea urged the companies to "enter into partnerships" with "American union members" and said joint ventures "that manufacture electric vehicle batteries would be made stronger by collective bargaining relationships" with U.S. unions.

Biden is set to host South Korean President Yoon Suk Yeol this week for a summit.
