Measuring Zn Transference with Precision: Insights for Dendrite‐Free Zinc Metal Anodes (Adv. Mater. 46/2025)

Measuring Zn Transference This study shows that Zn ion transport critically governs Zn battery performance. While adding potassium co-salt boosts conductivity, it lowers Zn ion transference, causing concentration gradients and unstable plating (dendrites). Conversely, higher Zn ion transport facilitates uniform deposits and durable cycling — highlighting that conductivity alone cannot guarantee dendrite-free Zn anodes. More details can be found in the Research Article by Maria R. Lukatskaya and co-workers (10.1002/adma.202502245).
