GM EV battery cell production to restart at Ohio plant

• The Ohio plant ceased battery-cell production in January 2026 due to a drop in EV consumer demand
• GM and LG's Tennessee joint-venture plant has pivoted from EV batteries to energy storage system batteries
• Samsung SDI recently purchased GM's stake in a separate joint venture for an under-construction Indiana battery plant

GM EV Battery Cell Production to Restart at Ohio Plant

General Motors and LG Energy Solution's joint venture Ultium Cells plant in northeast Ohio is set to resume battery cell production next week after a seven-month shutdown. The facility halted operations in January 2026 due to declining consumer demand for electric vehicles.

Key Developments:

Starting Monday, the majority of previously laid-off workers will return to the facility, bringing total employment to 1,400 workers at the Ohio plant. Tom Gallagher, Ultium's vice president of operations, confirmed the restart timeline.

Broader GM Battery Strategy Shifts:

The restart comes amid significant restructuring of GM's battery manufacturing partnerships. The company's second Ultium joint venture plant in Tennessee has pivoted away from EV battery production and now manufactures energy storage system batteries instead.

In a notable strategic shift, GM recently sold its stake in a third battery joint venture to Samsung SDI. This transaction involves an under-construction Indiana plant that was originally planned to produce EV battery cells.

Market Implications:

The seven-month production halt underscores the challenges facing the EV industry as automakers grapple with slower-than-expected consumer adoption rates. The restart suggests GM anticipates improved demand or needs to build inventory ahead of future EV launches.

However, the Tennessee plant's conversion to energy storage systems and the Samsung SDI deal indicate GM is reassessing its battery production capacity and partnerships in response to market realities. This reflects broader industry uncertainty about EV demand trajectory and the need for flexible manufacturing strategies in the evolving electric vehicle market.
