Ford has begun production of LFP (lithium iron phosphate) battery cells at its BlueOval Battery Park Michigan plant in the United States.
This is presented as the first LFP cell mass production in the United States for mainstream electric vehicles (primary source: reporting based on Ford’s announcement). Because LFP has lower active-material density than NMC, there is a structural constraint requiring a higher electrode coating loading to secure the same capacity. The start of LFP cell mass production directly affects North American electrode coating process design.
Mechanism-Perspective Impact Analysis
A higher coating loading requires redesigning the slot-die gap and dryer residence time. For the same solvent composition, a choice must be made between extending the dryer zone length or lowering the line speed, and in the initial ramp-up phase of a newly built line, managing coating-thickness deviation emerges as the key variable for safety-factor verification (estimate: a general process constraint inherent to LFP electrode characteristics; actual line speed and loading should be confirmed after field measurement). Because the Michigan plant is the first case in North America, there is a lack of reference precedent for coating process parameters, requiring a conservative approach to initial yield management.
Per electrive.com (June 18, 2026) and CnEVPost (June 30, 2026), the plant was completed in June 2026. The originally planned investment of USD 3.5 billion and 35 GWh capacity were both scaled back to USD 2.0 billion and 20 GWh during a project restructuring in November 2023. As designed at completion, the plant can supply batteries for roughly 400,000 EVs, and the workforce is planned to grow to 800 by year-end before eventually reaching 1,700 (a trajectory consistent with the earlier-cited ‘500+, adding 300 by year-end’).
Per Repairer Driven News (June 18, 2026), Ford operates a four-level employee certification system (Level 1: classroom training required before floor access; Level 2: hands-on operation under expert guidance; Level 3: independent operation and continuous-improvement contribution; Level 4: qualified to train other employees), and 87% of production staff currently hold Level 2 certification. Training spans skills from electrochemistry to robotics and software, alongside clean-environment operation including fine-particle control, with a quality target described at the parts-per-billion defect level.
Spec Comparison Table
| Item | NMC Line (reference) | When Converting to LFP Line |
|---|---|---|
| Active-material loading | Baseline | Relatively higher (to secure capacity) |
| Dryer residence-time requirement | Baseline | Tends to increase (estimate) |
| Production start | – | August 2026, BlueOval Battery Park Michigan |
| Target market | – | First for mainstream North American EVs |
| Investment / capacity | – | Originally USD 3.5B / 35 GWh → rescoped Nov. 2023 to USD 2.0B / 20 GWh (~400,000 EVs) |
Design Reflection Checklist
- Redesign slot-die gap and dryer zone length (or line speed) for the coating loading
- Set management criteria for corner radius in prismatic can forming
- Re-check can thickness and weld bead strength after confirming truck cell capacity and dimensions
- Set coating thickness variation limits for the initial ramp-up period
One-Line Summary: North America’s first mainstream-EV LFP cell mass production requires dryer redesign to accommodate higher coating loading and management of initial ramp-up thickness deviation.
