SEMCORP to open battery separator film plant in Ohio

Battery materials provider SEMCORP Advanced Materials Group plans to invest $916 million in a facility for manufacturing battery separator film in Sidney, Ohio.

The company will build the new 850,000-square-foot facility at the Sidney Ohio Industrial Park. “Our Sidney site will be America’s largest manufacturer of separator film for EV batteries,” said SEMCORP co-founder and CEO Paul Lee.

“SEMCORP chose the Sidney location because of the state’s impressive commitment to vocational education, preparedness for a large-scale project like ours, and proximity to key customers,” said Group VP of Global Projects James Shih.

“SEMCORP is currently the largest lithium-ion battery separator film producer in the world, with five billion square meters in annual base film production capacity across six manufacturing facilities,” says the company. The Sidney facility is part of SEMCORP’s plan to increase this capacity by eight billion square meters by 2026.
