Smyrna plant surpasses five million U.S.-made LFP cells

FIXX Energy reported producing more than five million lithium iron phosphate prismatic battery cells at its Smyrna, Tennessee, facility since converting the plant to LFP cell production in April 2025.

FIXX says the five-million-cell cumulative output represents roughly 5 GWh of energy-storage capacity. The cells are manufactured for grid-scale energy storage systems and deployed in projects nationwide. The company presents the milestone as evidence of operating U.S. battery-cell production; claims about tax-credit eligibility and broader industry investment are not necessary to establish the production milestone.
