Tuning Anode Morphology Through Strategic Cathode (Global) Current Manipulation: A Modeling and Simulation Study

Year: 2025

Type: article

Abstract: The evolution of metal anode–electrolyte interfaces critically impacts the safety and performance of metal anode batteries. We present a two-dimensional moving boundary model that simulates zinc anode morphology under high discharge–low charge (HD–LC) and low discharge–low charge (LD–LC) protocols. The model predicts interface flattening with HD–LC cycling, validated by symmetric cell experiments. LD–LC, however, does not show any change in interface morphology. Our findings highlight that cathode current modulation can effectively control interfacial morphology, offering a simple, yet powerful strategy to suppress dendrite growth and enhance metal anode battery safety through current control.
