Samsung SDI to Start US LFP ESS Cell Production in October

Published: Aug 4, 2026 19:38
Samsung SDI said its US prismatic lithium iron phosphate (LFP) battery cell production line for energy storage systems (ESS) has entered mass production quality validation and is scheduled to begin production in October 2026, with customer deliveries starting before year-end. The company said ESS orders have already secured a substantial portion of its production capacity through 2029 and demand is expected to exceed capacity from 2028, prompting a review of additional capacity expansion. Samsung SDI has also established a Non-FEOC-compliant LFP supply chain to support the US ESS market.
