Abstract
An electrochemical cell comprising a zinc electrode in an electrolyte solution wherein the electrode is formed from a zinc powder compacted to a density of at least about 6.5 g/cc to substantially reduce the corrosion of the zinc electrode and the consequent evolution of hydrogen gas without resorting to the addition of mercury to the electrode.
