3D Artificial Array Interface Engineering Enabling Dendrite-Free Stable Zn Metal Anode

Abstract

Highlights The design concept of 3D artificial array interface engineering was proposed to achieve eliminated volume stress, preferred orientation growth and dendrite-free Zn metal anode. The mechanism of MXene array interface on modulating the growth kinetics and deposition behavior of Zn atoms were firstly uncovered at a multiscale level. The engineered electrode exhibits comprehensive enhancements in the resistance of corrosion and hydrogen evolution reaction, as well as the rate capability and cyclic stability. 3D MXene array@Zn/VO2 batteries with enhanced rate performance (214.1 mAh g−1 at 10 A g−1) and cycle lifespan can be demonstrated.
