Inhibition Of Hydrogen Formation With Calcium Hydroxide On Zinc Electrode Of Film-Type Manganese Battery

A manganese dioxide (MnO2) layer and zinc (Zn) layer are used as the cathode and the anode to develop film-type manganese battery, in which a stack of a MnO2 layer, gel electrolyte, and Zn layer are sandwiched between two plastic layers. This paper describes the chemical equation of swelling control upon the film-type manganese battery. We examined the reduction of hydrogen formation, by using calcium hydroxide Ca(OH)(2) as an additive in the electrolyte of film-type manganese battery. The phenomena or an effect of reduced hydrogen gas was proven by cyclic voltammogram, X-ray photoelectron spectra (XPS), and volume of hydrogen formation. The amount of H-2 gas generation in the presence of Ca2+ ion was reduced from 4.81 to 4.15 cc/g-zinc (14%), and the corrosion of zinc electrode in the electrolyte was strongly inhibited as time passed.
