Abstract

Abstract: Lithium (Li) metal is considered as the most promising anode material for rechargeable high‐energy batteries. Nevertheless, the practical implement of Li anodes is significantly hindered by the growth of Li dendrites, which can cause severe safety issues. To inhibit the formation of Li dendrites, coating an artificial layer on the Li metal anode has been shown to be a facile and effective approach. This review mainly focuses on recent advances in artificial layers for stable Li metal anodes. It summarizes the progress in this area and discusses the different types of artificial layers according to their mechanisms for Li dendrite inhibition, including regulation of uniform deposition of Li metal and suppression of Li dendrite growth. By doing this, it is hoped that this contribution will provide instructional guidance for the future design of new artificial layers. Abstract : Anode layering : An artificial layer coated on an anode can effectively inhibit Li dendrites by efficiently regulating the uniform deposition of Li and/or mechanically suppressing the growth of Li dendrites, which enables a stable Li metal anode for high‐performance rechargeable batteries.
