Smyrna, Tennessee facility reaches a new production milestone as demand for domestic energy storage accelerates

SMYRNA, Tenn., Nov. 12, 2026 /PRNewswire/ — FIXX Energy, the first American-owned and operated manufacturer of lithium iron phosphate (LFP) prismatic battery cells for grid-scale energy storage systems (ESS), has produced more than five million cells at its Smyrna facility since converting the plant to LFP cell production in April 2025. Combined, the cells represent roughly 5 GWh of energy storage capacity, enough to carry 1 million U.S. homes through an evening peak. Laid end to end, they would stretch from FIXX’s Tennessee plant to Washington, D.C.

FIXX’s cells are deployed in battery energy storage projects nationwide, strengthening the electric grid and making energy more reliable and affordable for American homes and businesses. FIXX Energy and its cells help integrators and end users qualify for Section 45X Advanced Manufacturing Production Tax Credits and Section 48E Investment Tax Credits, including the domestic content bonus, under the One Big Beautiful Bill Act.

“Five million cells is five million proof points that America can build the energy storage foundation our grid needs, right here at home,” said Jeff Juger, CEO of FIXX Energy. “Our team in Smyrna has demonstrated what American manufacturing can accomplish. Every cell we’ve produced has taught us something, and we’re finding new ways to put that experience to work, including using artificial intelligence to drive further improvements in quality, efficiency, and cost. As demand for energy storage continues to grow, we’re proud to be delivering the reliable, American-made battery cells our customers need.”

The milestone also reflects the Town of Smyrna’s long-standing support for the facility, which began operations in 2012.

“Smyrna has a proud legacy of advanced manufacturing, and reaching five million cells produced is a tremendous achievement for both FIXX Energy and our community,” said Mary Esther Reed, Mayor of Smyrna. “This milestone is a direct testament to the dedication and skill of our local workforce. We are proud that these battery cells are being built right here in Smyrna.”

FIXX is proud to contribute to America’s growing energy storage manufacturing base. According to the U.S. Energy Storage Coalition, domestic battery module and system manufacturing capacity now exceeds total U.S. project demand, but battery cell production still lags, leaving a critical gap in a fully domestic supply chain. FIXX is helping close that gap, and its Smyrna facility is part of the energy storage industry’s $100 billion commitment to build American factories and buy American-made batteries, an investment expected to create more than 350,000 American jobs by the end of the decade.

“Energy storage has proven essential for ensuring regional power grid reliability and lowering electricity prices. As we race to keep up with surging demand for electricity and energy storage resources, our continued success depends on the strength of our U.S. supply chains and investment in American factories,” said Noah Roberts, Executive Director of the U.S. Energy Storage Coalition. “FIXX’s milestone shows what that investment means for American communities: more manufacturing jobs and greater energy security.”
