Read your last post on this topic too. Really love seeing these Mr. Science type experiments. This one is my favorite.
Is there some sort of copyright preventing manufacturers from selling these diy batteries online or in stores? I suspect it has more to do with incredibly effective withholding of information, that is isn't taught in basic science, engineering, and electrician training, and the bogus label of psuedoscience.
So far, your battery appears it might be far longer lasting, efficient, and cheaper. Only drawback appears to be size and time spent maintaining it.
