I want to make silver chloride cathodes for a magnesium salt water battery. Are there any tips on how to proceed?

I hope to melt the silver chloride in a covered ceramic crucible in an electric furnace, then cast a small ingot. This ingot will be pressed and rolled into a thin sheet. Silver chloride is nonconductive and is made conductive by superficially reducing the surface to silver by immersion in a photo-graphic developing solution. By forming a silver outer surface that is porous, no base grid need be used with silver chloride.

Any help or direction to information is appreciated so I don't have to "reinvent the wheel".

    $\begingroup$ Silver chloride is not a metal, you can't roll it. $\endgroup$ Apr 26 at 1:11

    $\begingroup$ The wikipedia article on silver chloride says it can be hot pressed into windows and lens shapes. $\endgroup$

    $\begingroup$ @EdV Jup, just like KBr (at RT even), but then you end up with a solid piece, nothing porous. I'm not clear how this battery is supposed to work. $\endgroup$

  • $\begingroup$ It looks trickier than using a support grid. It should be the other way around, perhaps. I.e. silver grid / foil with some AgCl deposited onto. That can be easily done electrochemically, and if one stops the deposition while the process is ongoing, the contact to the underlying metal electrode is guaranteed. Look for quasi Ag/AgCl electrode. $\endgroup$

    $\begingroup$ @Karl Yeah, so like making a KBr pellet in a press. I also have no idea how the proposed cell would work. $\endgroup$
