EV Battery Supplier Sets Up Operations in Kentucky.

LOTTE is one of South Korea’s largest conglomerates, serving a wide variety of industries and employing more than 80,000 people. The company’s latest enterprise, a joint venture between LOTTE Chemical and LOTTE Aluminium, will supply partners in the electric vehicle (EV) industry with cathode foil—an integral component of lithium-ion batteries that power the vehicles.


LOTTE selected Gray to design and build the greenfield production plant on a 40-acre site in Elizabethtown, KY. The facility will be located just miles away from the BlueOval SK Battery Park, another South Korean joint venture and a major production facility for EV batteries that’s slated to begin operations in 2025.

Gray’s scope for the project includes engineering, pre-construction, BIM/VDC, and design-build services for the 327,000 s.f. production plant and several ancillary buildings, including corporate offices, a pump house, and waste storage space.


In addition to the design-build of the facility, Gray is responsible for process utilities including chilled water, air piping, oil piping, coolant tanks, and water chillers. The customer’s unique process equipment required Gray to pour 24″ reinforced concrete slabs to account for the equipment’s considerable weight. Other process equipment includes bridge cranes, cooling oil tanks, an aluminum scrap piping & bailer system, and an automatic storage & retrieval system (AS/RS).
