Possibility and advantages of an anodic-type inhibitor for Zn/MnO2 dry batteries

In developing mercury-substituting inhibitors for zinc/manganese dry batteries, the authors have discovered an anodic-type composite organic inhibitor (designated as PA) which is quite effective in suppressing the corrosion of zinc during cell storage, yet will not impede the dissolution of zinc during cell discharge. Moreover, the inhibitor PA has a unique advantage in that the corrosion of zinc is inhibited irrespective of the conjugate cathodic process.
