Hi,
I need some advise regarding assembly of coin cell CR2032 batteries. I encountered problem with finding good tool for cutting fine shape battery electrodes. I noticed cheap hammer hole punch deform electrodes on the edges. Other options is quite expensive (https://www.mtixtl.com/CompactPrecisionDiscandRingCutter-MSK-T-07.aspx)
Maybe there is some cheaper alernatives (in metric system)?
Hello Jurgis Pilipavičius ,
I assume you already have the CR2032 cases:

What material are you cutting? For cutting most electrode materials we use the following set from Facom:
https://uk.rs-online.com/web/p/punch-die-kits/3006360/
Manufacturer part number: 245.J1
RS part number: 300-6360
It has diameters ranging from 3-30 mm. We must have tried around 5 different brands of punches, but this one seems to perform the best.

Thanks for the answer,
So the current collector is aluminum foil, but later I think i will need to use SS steel foil 0.01mm thick. On the current collector is tape-casted ceramic film with binder
you can buy from aliexpress, it is very cheap and useful for cutting electrode with different size , Look what I found on AliExpress
