Zinc battery goes to anode-free

Abstract

The zinc (Zn) batteries have challenges include uncontrollable dendritic growth, unreasonable negative to positive ratio and limited areal capacity. This highlight presents the latest development to resolve the uncontrollable Zn dendrite formation at high areal capacities of 200 mAh·cm–2 through a two-dimensional metal/metal-Zn alloy heterostructured interface. The anode-free Zn batteries with an attractive and practical pouch cell energy density of 62 Wh·kg–1 enlighten an arena towards their commercialization.
