Saft Solid State (3S) program overview

2

Program with 2 related targets What will Solid State deliver? Keys to success

• 1. Develop state-of-the

art high energy Li-ion cell with a liquid electrolyte (catch up with the best in class)

• 2. Develop a true Solid

State Li-ion system

– High energy – Lower cost – Improved

safety

– Long life – Potential other

benefits

– Ionic conductivity equal or

better to liquid electrolyte

– Solid electrolyte membrane

mechanically able to prevent Li dendrites from causing a short circuit

– Active materials

electrochemically stable with the chosen solid electrolyte

– High speed manufacturing

processes creating a solid matrix structure vs the current “wet sponge” structure
