I'm trying to make a 2032 coin cell to analyze the electrochemical properties of solid electrolytes. So I'm using a high-pressure hydraulic press to manufacture solid electrolyte disks. I'm trying to make it smaller than 200㎛, but I'm having difficulties such as electrolytes breakage. So I tried to adjust the thickness through the polishing process, but it was not easy. So I'd like to know how you usually manufacture it. Also, if you have any papers and materials to refer to, please recommend them.

You can use PEO (polyethylene oxide), or PVA (polyvinyl alcohol) matrix with addition of organic electrolyte or inorganic (as you wish) inside matrix composition, which can work as electrolyte and separator

You can use swagelok cell instead of coin cell. In this case, the tickness is not an issue for fabrication (only). But yes, thickness plays a vital role on performance in solid-state battery as it is related to host ion insertion/extraction. You can make study on that too (performance on thickness variation). I'm sure, you will find some interesting results and conclusion. you can find many artilcles regading this. For example, I'm sharing link of one article here-
