However, dendrite formation and side reactions involving Zn corrosion and hydrogen evolution at the Zn electrode restrict the practical application of ZIBs. In this study, sodium succinate (SS), a common leveler and brightener in Zn electroplating, is explored as a functional electrolyte additive in ZIBs. Theoretical and experimental results indicate succinate ions can preferentially adsorb on the Zn electrode surface compared with water molecules. The adsorbed succinate ions can beneficially affect Zn2+ diffusion and cover the active sites for side reactions, resulting in more uniform Zn deposition and a protected Zn electrode. With the addition of 0.04 M SS to 2 M ZnSO4, the lifetime of the ZIB is significantly improved. A cycling stability of over 7100 h at 1 mA cm−2 is achieved, along with an ultrahigh average Coulombic efficiency of 99.6% in Zn||Cu cells, as well as a stable plating/stripping behavior of over 1800 h at 2 mA cm−2 in Zn||Zn cells. Even at a high current of 10 mA cm−2, both Zn||Zn and Zn||Cu cells employing the newly designed electrolyte demonstrate much improved performance. Full cells with Zn and I2@activated carbon electrodes in the designed electrolyte exhibit both higher capacity and capacity retention (87%) compared with batteries using pure 2 M ZnSO4 electrolyte. The exploration of SS as a functional electrolyte additive for ZIBs connects the use of levelers and brighteners in Zn electroplating with the study of ZIBs.T06-P03 University of Alberta | Publication | 2024-12-01 | | Revealing Zn Stripping and Plating Behavior in ZnSO4, Zn(ClO4)2, and ZnCl2 as a Function of Current Density and Capacity in Aqueous Zinc Ion BatteriesZn-ion batteries (ZIBs) are promising candidates for stationary energy storage due to
their enhanced safety and cost-effectiveness. However, challenges such as dendrite
and by-product formation severely restrict their practical application. Numerous
strategies have been proposed to address these issues, yet only a few fundamental
studies have systematically investigated Zn plating and stripping behavior on Zn
electrodes or the role of anions in these processes. In this study, correlations between
electrolyte characteristics and Zn stripping/plating behavior are established. The
reversibility of Zn followed the order ZnSO4 > ZnCl2 > Zn(ClO4)2. Several trends were
observed. Zn preferentially deposited on protruding areas in all electrolytes. At a
constant current density, increasing the areal capacity led to the formation of larger Zn
particles. At a fixed areal capacity, increasing the current density resulted in smaller Zn
deposits but a greater number of individual Zn islands. Zn in Zn(ClO4)2 exhibited
preferential stripping from the Zn substrate, whereas in ZnSO4 and ZnCl2, more Zn
was stripped from deposited Zn. These findings provide fundamental insights into Zn
plating and stripping behavior and may inspire new strategies to enhance the
performance and reversibility of ZIBs.T06-P03 University of Alberta | Publication | 2025-04-28 | |
