McCarthy Building Companies Selected by ICL Group to Build $400 Million Battery Materials Manufacturing Plant in St. Louis


Expected to be the first commercial-scale LFP battery materials manufacturing plant in the United States

McCarthy Building Companies has been selected by ICL (NYSE: ICL) (TASE: ICL), a leading global specialty minerals company, to build a $400 million state-of-the-art lithium iron phosphate (LFP) battery materials manufacturing plant in St. Louis. The new facility is expected to be the first commercial-scale LFP battery materials manufacturing plant in the United States and will serve as the foundation for ICL’s global battery materials business.

The 140,000-square-foot battery materials plant is expected to produce 30,000 metric tons for use in batteries that can store energy needed to run electric vehicles, charging stations or on the electric grid. ICL’s investment in the plant was augmented by a $197 million grant from the U.S. Department of Energy.

“McCarthy is proud to partner with ICL in supporting our nation’s path to sustainable energy production and the ever-growing demand for clean energy industries,” said Kristyn Newbern, Director of Project Development at McCarthy. “Partnering with ICL to build this facility in our hometown is especially significant as part of our longstanding commitment to our community, as well as a testament to our strength in building advanced technology and manufacturing facilities.”

The new plant will be located on ICL’s existing Carondelet campus in St. Louis, which is recognized by the Justice40 initiative as a disadvantaged community. In addition to creating 800 to 900 union construction jobs, the new facility is estimated to create 150 high-paying union and professional jobs for ICL.

According to ICL’s press release, “LFP is one of the fastest-growing sectors of the battery industry, as this technology offers superior safety at a lower cost and with a longer life. By 2031, E Source forecasts global demand for iron phosphate-based cathode active materials will reach more than 3 million tons, for a market value of more than $40 billion, due to a shift toward the safer and lower-cost cathode materials used in more affordable EVs and in energy storage solutions. The new facility represents a significant expansion of ICL’s energy-storage portfolio and demonstrates the company’s commitment to developing high-quality specialty projects for agriculture, food, energy and industrial applications.”
