Suitable binders include poly[2,2'-(m-phenylene)-5,5'-bibenzimidazole] (PBI), poly[2,5-benzimidazole] (ABPBI), polybenzoxazole (PBO), polybenzothiazole (PBT), and combinations thereof.

phenolic resins, epoxy resins, furan resins, xylenol-formaldehyde resins, urea resins, melamine resins, aniline-formaldehyde resins, Friedel-Crafts resins,unsaturated-polyester resins, polyvinylalcohol, polyacrylic resin, polyvinylbutyral, polyvinylpyrrolidone, polyvinylacetate, polystyrene, polyisobutylene, and others

unsaturated-polyester resins. this might be worth a try. Cheap and easy to find. Boat hull repair. walmart........

Yikes, this thread got technical real fast:  here is a link to a portable zinc-air battery for charging mobile devices.  http://www.instant-power.com/instantpower.pdf ..it supplies 3300mAh.

It doesn't matter what you use to create power. It will always be expensive! Dupont will take the place of the oil companies!!!!!

No,
you can do it very cheaply now.

When I will put the graphite-acrylic mix onto a
stainless steel mesh I will get into the Ohm range for the
inner electrode resistance and not more in the
KiloOhm range.

This will also get me a cell simular to the Zinc air cell
but just with alufoil.

Have a look at the latest videos:
