The supplier captured the contract for the third lithium iron phosphate line at StarPlus Energy, the North American battery manufacturing venture operated by Samsung SDI and automaker Stellantis. The third line equipment contract carries a value of 5.0 billion won ($3.7 million), according to a regulatory single-sales disclosure filed by Innometry with the Korea Exchange on Aug. 27. That single award represents 12.8% of the equipment maker's 2025 annual revenue of 38.6 billion won ($28.8 million), the filing showed. The delivery period for the third line contract runs through Dec. 31, 2027. Equipment shipped under this order will equip StarPlus Energy to produce 300 ampere-hour prismatic cells for global energy storage system integrators. The transaction follows a previous contract disclosed on Jan. 19, when Innometry booked 5.5 billion won ($4.1 million) to supply inspection hardware for the plant's first production line. The initial line will produce 273 ampere-hour prismatic cells for the Samsung Battery Box 2.0, a containerized energy storage product supplied to US grid infrastructure developers. Innometry revised the delivery schedule for the first line contract to Feb. 26, 2027, supporting production preparations ahead of the line's planned operational startup in October 2026. A separate disclosure on June 1 assigned 5.3 billion won ($3.9 million) in inspection systems to the plant's second line, which produces cells for Tesla stationary storage systems. Across all three energy storage lines, Innometry has secured a cumulative 15.8 billion won ($11.8 million) in inspection orders from the Indiana manufacturing complex. The cumulative order total equals 40.9% of Innometry's total consolidated annual revenue for 2025. Computed tomography inspection systems use high-frequency X-ray scans to create three-dimensional images of battery cells without cutting the aluminum outer casing open. The automated machines inspect internal anode and cathode alignment gaps to confirm electrode overhang margins along the wound or stacked jelly-roll structures. The hardware detects microscopic foreign metallic particles and foil burrs in-line before cells proceed to module packaging and electrical formation. Identifying internal physical anomalies prevents short circuits between positive and negative plates, eliminating a leading cause of thermal runaway in stationary battery storage banks. Samsung SDI altered its manufacturing layout at the Indiana plant to respond to shifting demand in the North American power sector. The company originally planned to retool two of its four automotive cell production lines at the Kokomo facility into dedicated energy storage lines. The battery maker added a third conversion line to fulfill supply agreements with regional grid operators and developers building electricity infrastructure for artificial intelligence data centers. South Korean cell producers are converting underutilized automotive assembly capacity into stationary storage manufacturing lines to offset slower growth in electric vehicle retail deliveries. Lithium iron phosphate chemistry provides longer operational cycle life, greater thermal stability and lower raw material expense than nickel-cobalt-aluminum formulations. Retooling automotive production lines for stationary storage cells requires dedicated non-destructive hardware because large-format prismatic cells use thicker casings and wider internal electrode stacks. Higher material thickness requires stronger X-ray radiation sources and specialized software algorithms to reconstruct internal layers at standard conveyor line speeds. Innometry developed continuous conveyor inspection hardware that rotates internal imaging sensors around moving cells rather than spinning the heavy battery body itself. The equipment maker shipped production units of its next-generation inline inspection hardware to high-capacity battery manufacturing sites on Aug. 21. The vendor posted first-quarter 2026 revenue of 17.5 billion won ($13.0 million), up 102% from a year earlier, returning to an operating profit of 200 million won ($149,000). Contractual confidentiality provisions prevented Innometry from naming Samsung SDI or the StarPlus Energy venture directly in its regulatory exchange filings. Samsung SDI will begin commercial cell production on the first Indiana energy storage line in October 2026. ## Impact map | Event | Korea | China | Japan | Global impact | | --- | --- | --- | --- | --- | | ESS inspection order sweep | equipment vendor secures 15.8 billion won | LFP cell builders face US manufacturing competition | component makers align with US lines | automated defect testing expands in utility storage | ## In this story - **Companies:** Innometry, Samsung SDI, Stellantis - **Tickers:** 302430.KQ, 006400.KS, STLA - **Exposed:** Tesla - **Policy:** Subsidies, Tariffs - **Impact:** Supply Chain, Order Book, Capex ## Primary sources 1. thelec.net 2. zdnet.co.kr 3. kdpress.co.kr 4. etnews.com 5. thelec.kr --- Cite as: East Asia Brief, "Innometry sweeps Samsung SDI US ESS battery inspection orders," September 1, 2026. https://eastasiabrief.com/batteries-ev/innometry-sweeps-samsung-sdi-us-ess-battery-inspection-orders-152
