Original Abstract
This work discussed a process of decomposition of alkaline supersaturated zincate solution (SZS) based on KOH and monitored growth of zinc oxide crystals in broad timescale. Decomposition of SZS is an important process taking place in the entire volume of supersaturated zincate solutions that are the mostly used electrolyte for Ni-Zn or Zinc-Air batteries. SZS is formed primarily at a short distance from the negative electrode during fast discharging of zinc anode or in entire volume of electrolyte in final stage of discharging. A supersaturated 6 mol/l KOH solution was prepared by oversaturation at higher temperature with subsequent cooling. Initial level of supersaturation reached 0,9 mol/l than its balanced concentration in a potassium hydroxide solution.
