which reference electrode can be used to study corrosion of the metal in Li-based battery electrolyte?
As LiPF6 can produce HF which can dissolve the glass, or if you use Ag/AgCl reference electrode then the leaking of the KCl solution can contaminate the electrolyte.
Any suggestion on a suitable reference electrode which can be used with LiPF6 in EMC:DMC solution?
This depends on what metal is reacting to cause corrosion, and whether the reference electrode is meant to serve any purpose other than a stable reference potential to the working electrode.
You're probably aware that a 3-electrode cell for studying Li-ion cells usually applies lithium as the (pseudo-)reference electrode, and none of the reactions in the cell would normally be considered corrosion. The only metals that might participate in a corrosion-like redox would be the current collectors - Al on cathode or Cu on anode - is this what you're asking about?
Hi, Anne Sawhney Thank you so much for adding the answers it is helpful. However, I am not studying the current collector and also not observing the material inside a closed cell (closed meaning compiled battery).
Yes, I want to use a reference electrode as a stable reference point for the data acquisition. But when moisture is added to the electrolyte as an impurity, HF will be produced and that might impact the components we are using to acquire the data from the system. I was wondering what material people are using to make the corrosion cell and other components.
If you have any experience of this then I would appreciate the guide.
Cheers
