Zinc-oxygen secondary battery has been noticed as an automobile storage battery. An uniform and smooth deposit of zinc must be obtained from the alkaline electrolyte containing zincate ion during charging process for the purpose of better charging characteristic and longer life of the battery.When an electrode, which had been anodically polarized to the passive state, was used, the polarization was less than that on the bare surface and did not bring about reproducible data. It was due to the evolution of hydorogen during the deposition and local deposition of zinc on the oxide surface. In alkaline zincate solution, the deposition of dendritic zinc during charging was the most serious problem.However, an uniform and smooth deposit was obtained during charging by addition of piperonal to the electrolyte. Piperonal was decomposed in the electrolyte during the use for a long time, but it was improved by coaddition of hydrogen peroxide. Moreover, the charge-dischage cycle was much lengthened by addition of trietlylenetetramine. In such a case, a smooth deposit was also obtained after 5 cycles, though high polarization was produced in charging.
