Measuring Zn Transference with Precision: Insights for Dendrite-Free Zinc Metal Anodes.

ABSTRACT: Electrolyte engineering in Zn-metal batteries frequently employs alkaline metal salts to enhance conductivity and reduce overpotential for Zn plating. While these additives improve conductivity, the presence of more mobile alkali cations can negatively affect the Zn²⁺ transference number. Optimizing this property is crucial for high-rate performance, efficiency, and safety, as high Zn²⁺ transference number minimizes concentration polarization and dendrite formation during high-current cycling. However, reliably measuring the transference number in non-binary electrolytes presents significant experimental challenges due to dynamic Zn metal interfaces, rendering traditional methods ineffective. Here, we use a modified Hittorf-type method to measure Zn²⁺ trans
