How the Kinetic Balance Between Charge-Transfer and Mass-Transfer Influences Zinc Anode Stability: An Ultramicroelectrode Study.

ABSTRACT: Aqueous zinc-metal batteries (AZMBs) represent a promising frontier in battery technology, offering sustainable and safe alternatives to traditional non-aqueous batteries. Despite their potential, understanding the kinetics of zinc electrodeposition-a critical factor in AZMB performance-remains underexplored. Utilizing voltammetry on ultramicroelectrodes, we investigate how scan rate influences key processes of nucleation and growth during Zn²⁺ electrodeposition. The findings highlight the efficacy of the Butler-Volmer formulation in capturing electron-transfer kinetics, contrasting with complex electron transfer kinetic models used for non-aqueous battery chemistries. We clearly demonstrate that there is a strong dependence of scan rate on the measured value of kinetic paramete
