High-performance magnesium metal batteries <i>via</i> switching the passivation film into a solid electrolyte interphase

Abstract

Mg²⁺ electroplating has been an obstacle for Mg metal batteries due to the passivating nature of Mg metal. Here, a unique current collector based on an amorphous MgO-wrapped Zn-skeleton enabled Mg²⁺ electroplating for a high-voltage Mg metal battery.
