The second example is a polystyrene which has an alkylated amine group on it, which is positively charged, allowing the negative ion shown as chloride, to be exchanged for another chloride or some other negative ion. A third kind of polymer separator is just a porous membrane that doesn't have any ionic groups and allows ions of either charge to flow through it, as well as solvent, and redox active materials, if any. However it does serve to keep the two sides of a battery with solid electrodes from shorting out. Membranes of this type are made of some inert material such as polypropylene....
