@Michael_A_Hope Hi Michael, Not sure how the lithiation stages would be in presence of ionic liquid electrolytes. This is something that we need to look at. The SEI will be different when compared to organic carbonate based electrolytes.

@Maria_Shebin Nice video! I was wondering how much you expect the graphite lithiation stages to be different when using an ionic liquid? (And why?) Or do you expect more differences in the SEI that forms?

Glad to share some of my work on 'Lithiation stages of graphite in lithium-ion battery studied using NMR spectroscopy' at Global NMR Discussion Meetings Twitter Conference 2023 #GlobalnmrTC2023

@PuDuan143907 Lithium intercalated in graphite is not stable if exposed to atmosphere. We disassemble the cell and pack the sample in NMR rotors inside a glove box and run NMR as soon as possible once the rotor is taken out.

@Maria_Shebin Crytal clear talk! I'm not familiar with the lithium business, so I'm sorry if my question is silly. I'm curious how stable is LiC6 when exposed to air. Will oxidation be a concern during the NMR experiment?

@blkwiln Hi Blake Thank you. For NMR measurements, the graphite material from the electrode is scraped out carefully, and is ground with KBr to reduce the electrical conductivity and packed to MAS rotors.
