This paper explores how the physical architecture of a zinc anode—specifically its porosity and connectivity—influences battery efficiency. Using COMSOL Multiphysics, the researchers developed a 3D model based on tomography images to compare different microstructures (lamellar vs. cellular). The study highlights how realistic 3D modeling can predict local reaction kinetics, ion transport, and pore clogging, providing a roadmap for designing longer-lasting, rechargeable zinc-air batteries.
