Saft Solid State (3S) program overview Program with What will Solid State Keys to success 2 related targets deliver? – High energy 1. Develop state-of-the – Ionic conductivity equal or better to liquid electrolyte art high energy Li-ion – Lower cost – Solid electrolyte membrane cell with a liquid mechanically able to prevent electrolyte (catch up – Improved Li dendrites from causing a with the best in class) safety short circuit 2. Develop a true Solid – Active materials – Long life State Li-ion system electrochemically stable with the chosen solid electrolyte – Potential other – High speed manufacturing benefits processes creating a solid matrix structure vs the current “wet sponge” structure 2 Saft proprietary information – Confidential
