Saft opens solid-state battery lines for electric aircraft

French battery maker Saft, a TotalEnergies subsidiary, has inaugurated solid-state battery production lines in Bordeaux for electric aircraft and space applications. The company claims up to 50% higher energy density than conventional lithium-ion cells and a 40% cut in CO2 emissions at the electrode stage via a dry electrode process.

• Energy density up to 50% higher than conventional lithium-ion
• Lines handle sulfide and polymer electrolytes at room temperature
• Dry electrode process cuts electrode-stage CO2 emissions by up to 40%
• Semi-solid-state cells delivered to Safran; evaluation starts next year
