ICL has broken ground on a $400 million St. Louis battery manufacturing plant. The project is set to be the first large-scale plant of its kind that manufactures lithium iron phosphate (LFP) batteries in the nation.

Situated on ICL’s Carondelet campus, the facility will encompass 140,000 square feet. It is expected to produce 30,000 metric tons of LFP, a component needed for electric vehicles, energy storage, mobility, infrastructure and more. The facility is anticipated to deliver in 2025.

The U.S. Department of Energy supplied a $197 million grant toward the project. In a statement at the groundbreaking ceremony, U.S. Secretary of Energy Jennifer Granholm said that the facility will contribute toward a strong U.S. supply chain of clean energy products.

In an effort to incentivize EV manufacturers and American-made EV products, the Biden administration is contributing grants toward related projects through the Inflation Reduction Act. Tesla, BMW and Mercedes are just some of the companies to recently announce billion-dollar investments into EV and battery production plants.

McCarthy Building Cos. is the battery plant’s general contractor. ICL also partnered with Aleees to establish a U.S.-based LFP supply chain.
