REALSEI (opeRando chEmical spAce- and time-resoLved quantification of Solid Electrolyte Interphase in hard carbon anode for sustainable sodium-ion batteries)

The scientific goal of the REALSEI research project is to apply and validate an experimental protocol to visualize the formation of the Solid Electrolyte Interphase (SEI) resolved in space and in real-time (operando) on the surface of Hard Carbon (HC) negative electrode in a Na+ ion battery (NIB), and correlate the bulk structure with the surface properties of the sample. To obtain this goal innovative space- and time-resolved operando experiments will be designed and implemented by exploiting X-ray advanced synchrotron techniques.
