Saft Opens Europe's First Solid-State Battery Production Line in France
TotalEnergies subsidiary Saft officially launched a solid-state battery pilot production line at its Bordeaux facility targeting aviation and space applications. The cells use sulfide-polymer electrolyte architectures achieving up to 50% higher energy density than liquid lithium-ion, produced with a solvent-free dry-coating process that cuts manufacturing CO2 by up to 40%.
- Sulfide-polymer electrolyte cells reach up to 50% higher volumetric and gravimetric energy density than liquid lithium-ion benchmarks
- Solvent-free dry-coating process cuts cell manufacturing CO2 by up to 40% versus conventional wet-slurry production
- Aviation and space markets are the initial target; the line is pilot-scale, not mass production, but marks industrial graduation
Why it mattersSolid-state batteries have been three years away for a decade; Saft opening a production line — even a pilot — moves the chemistry from laboratory to factory floor in Europe for the first time.
