3 generations of prototype cells

Synthesis of carbon host

matrixResults achieved:1. Improved cycling2. Higher sulphur

conversion3. Cheap materials

(< 5 EUR/kg)4. Sustainable

precursors

Selective separators

Functionalization of graphene oxide to prepare separator

layer with hydrophobic properties

Novel types of

electrolytes 1. Use of ionic liquids

2. Improved cyclability and coulombic efficiency

3. TRL-level 3-4 (1L of electrolyte delivered for prototypes by Solvionic)

Prototype assembly and tests

• Cells are assembled at Saft. • Cells are charged by using

constant current charge and discharged in different

conditions and temperatures including DST macro-cycle and tested by

Renault.
