Do the cathodes even work? Nobody knows.How can we know for sure that the cathodes that Zinc8 produced even work. From my recollection they had to redesign the cathodes because the original cathodes had a dendrite issue that needed to be overcome. So, has this been solved? Nobody knows because nobody has ever seen a working ZincAir battery to date yet the company wants you the investor to pour money into this pump and dump for a product that they won't even display to investors.
