I use lithium-ion polymers in electrochemical cells
Did you ever wonder why lithium-ion batterys are called lithium-ion polymer batterys? The answer is because they have a polymer that allows ions to
go through this thin plastic. It is relativly easy to cut the outside of a lithium battery off and unroll the four layers (two polymer layers, anode,
cathode.
The only problem is cleaning the plastic, any remaining material can be removed with a temporary electrocem. cell using salt water etc.
Now where to get the lithium-ion polymer battery, by definition these batterys are rechargable, you can ask your friends for their dead laptop
batterys; each laptop battery (normaly 8 or 12 cells) has about 4 feet by 2.25 inches of this stuff per cell.
Has anyone tried this?

If I understand you correctly, you're salvaging the polymer from lithium-polymer batteries to use it as an ion-selective membrane, right? Clever.
You might want to salvage the electrolyte too, as there might be some interesting solvents/ions in there.
One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

Any idea what ions besides Li+ the membrane will or won't pass?
I wonder if somebody could design a few experiments around this, to see what does and doesn't go thru it.

It would probably be best to ask the manufacturer of the membrane.

Bah! Experiments are more fun.
