The effect of interface heterogeneity on zinc metal anode cyclability

                The surface of a zinc metal anode was mapped using SECM. Slow Zn
                2+
                transport can be caused by an insulating SEI (ZHS or ZnO) or horizontally plated zinc. Fast Zn
                2+
                transport can be caused by a protruding morphology or a more conducting SEI.
