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.
