Abstract
Alkaline zinc-manganese dioxide electrochemical cell containing a small amount of an organosiliconate additive as a means for reducing the amount of mercury used in the zinc amalgam. The organosiliconates added to the anode are film forming organic wetting agents and can be used in mercury containing anodic zinc gels containing other gas suppressors.
