Answer:This is a small watch mercury battery. ... This helps prevent the collection of mercury into large droplets. During discharge, zinc oxidizes to zinc oxide, and mercuric oxide gets reduced to elemental mercury. A little extra mercuric oxide is put into the cell to prevent evolution of hydrogen gas at the end of its life
