We are going to fabricate silicon based anode materials on copper foil. We are targeting to enhance cyclic stability of anode as a result of Li ion insertion. In literature, mostly it has been done after coin cell fabrication. Is it possible to test that without coin cell fabrication in electrochemical work station by EIS and CV? If yes, then what should be complete electrode assembly? We are looking to use LiOH solution as an electrolyte, sample deposited copper foil as working electrode and Ag/AgCl as reference electrode. Will it work? Any suggestion or recommend from literature will be appreciated.
Your electrolyte will be substantially different, therefore the cycling characteristics of your electrode in this setup would be substantially different than those in a cell made using a standard Li-ion electrolyte. Can this difference be ignored for your publication?
If I tried to do this with my cells - and I wish I could - my first problem would be that my binder (CMC/SBR) would dissolve in any aqueous electrolyte. This binder seems to be the standard for Li-ion anodes, but lots of researchers ignore that and use PVDF/NMP. Does this apply to your anode?
Electrodes are often treated as if they perform in isolation, but the electrochemical efficiency of an electrode in any cell is dependent on both the electrolyte solvent and salt. This isn't just because of the SEI, it's fundamental to the charge transfer at the interface.
If you want to conduct CV and EIS without coin cell cycling, I recommend using a swagelok-type cell (some manufacturers are EL-CELL and redox.me) with a standard electrolyte that can be assembled in an inert environment then removed and tested with a standard potentiostat.
I recommend to pass via a (much) lower risk, intermediate experimental phase/step (intermediate-WE), testing first, a simpler anode[1] material, say, using a Carbon[2,3] (based anode materials), in order to check/verify the compatibility and reliability of all (many) other experimental parameters (and cell's materials: binder, etc.) .
