John B:
My best strongest cells were made from the carbon of 10 year old carbon/zinc D size batteries that would not hold a charge. But unfortunately that carbon would also in time start to dissolve the aluminum capacitor cans that I use, after a few months, especially if they weren't totally hermetic.
The aquarium activated charcoal seams to be working for some. But, I do agree that any metals needs to be treated, or it will be affected, and the cell stops working, especially when using salt electrolytes. I use no electrolyte just carbon and there is still something that bogs the cells down, in time. Maybe it is like pluged up nano tubes in the carbon. Just like charcoal water filters, that will only work for only so long.
