DETROIT, Aug 12 (Reuters) - A factory jointly owned by

General Motors ( GM ) and LG Energy Solution in

northeast Ohio is scheduled to restart production of battery

cells next week after a seven-month shutdown.

On Monday, a majority of laid-off workers will resume making

batteries at the Ultium Cells joint-venture plant, Tom

Gallagher, vice president of operations for Ultium, said in an

interview.

In total, 1,400 will be working at the facility.

The company ceased battery-cell production there in January

because of a drop in consumer demand for electric vehicles.

* The other GM and LG JV plant, in Tennessee, now makes

energy storage system batteries instead of EV batteries.

* Earlier this week, battery manufacturer Samsung SDI

purchased GM's stake in the joint venture the companies had

formed to make EV battery cells at an under-construction Indiana

plant.
