GM Sells Battery Plant, Eyes New Partnership
13 Aug
Summary
- GM sold its stake in a jointly built, unfinished battery factory.
- Samsung SDI acquired GM's share due to slower EV demand growth.
- GM and Samsung will now co-develop next-generation prismatic cells.
General Motors recently divested its 49.99% ownership in the SynergyCells joint venture, which was developing a battery plant in New Carlisle, Indiana. Samsung SDI, the joint venture partner, acquired GM's stake, citing market changes and a slower-than-anticipated rise in EV demand. This move allows Samsung SDI to control the factory's assets independently.
Concurrently, GM and Samsung SDI have entered into a new joint development agreement focused on next-generation prismatic battery cells. This partnership suggests GM's continued interest in prismatic cell technology for its future EVs, even as it relinquishes ownership of the manufacturing facility. The prior agreement, valued at approximately $3.5 billion, targeted significant annual capacity and job creation by 2027.
The shift from GM's current Ultium pouch cells to prismatic cells signifies a potential evolution in battery pack design. Prismatic cells, housed in rigid cases, may offer structural advantages and simplify module construction, potentially enabling more integrated cell-to-pack architectures. This strategic decision highlights GM's approach to managing capital risk in a fluctuating EV market.
