Abstract
Abstract The development of Zn-free anodes to inhibit Zn dendrite formation and modulate high-capacity Zn batteries is highly applauded yet very challenging. Here, we design a robust two-dimensional antimony/antimony-zinc alloy heterostructured interface to regulate Zn plating. Benefiting from the stronger adsorption and homogeneous electric field distribution of the Sb/Sb 2 Zn 3 -heterostructured interface in Zn plating, the Zn anode enables an ultrahigh areal capacity of 200 mAh cm −2 with an overpotential of 112 mV and a Coulombic efficiency of 98.5%. An anode-free Zn-Br 2 battery using the Sb/Sb 2 Zn 3 -heterostructured interface@Cu anode shows an attractive energy density of 274 Wh kg −1 with a practical…
