Abstract
In order to improve the properties of electrolyte solution for the nickel-zinc battery, the affection of the KOH and seven kinds of important additives (LiOH·H2O, KF·2H2O, K2CO3, (CH3)4NOH, C19H42BrN, (NaPO3)6, ZnO) on electrolyte solution performance is investigated with the experimental Uniform-Design method. The relationship of the electrolyte composition and the solubility of discharged products of zinc are determined by EDTA titration method; the effect of different electrolyte composition on corrosion of zinc is characterized by determining the hydrogen evolution volume. Based on regression analysis, the main influencing factor can be obtained. The best proportioning of electrolyte additives is gained by the multivariate regression fitting, on condition that the solubility and the velocity of hydrogen evolution are regarded as response variables. The optimal formula is as below: 41g KOH, 12g K2CO3, 0.15g (CH3)4NOH and 0.36g C19H42BrN per 100ml of electrolyte solution.
