Why Ohio?

Ohio’s vast history in the automotive industry and automotive supply chain as well as its overall proximity to resources, manufacturers, and end markets are two key factors making the state an ideal location for lithium battery manufacturers. The state’s commitment to innovation makes it a natural fit for the emerging electric vehicle supply chain and electric vehicle manufacturing opportunities. Ohio’s commitment to clean manufacturing with renewable energy and solar energy also makes it a prime choice for lithium-ion battery manufacturing.

SEMCORP chose the Sidney location because of the state’s impressive commitment to vocational education, preparedness for a large-scale project, the strong work ethic in the region, and proximity to key customers.
