Graphical Abstract

Will behave well if treated well: A simple chemical modification strategy was designed for the preparation of a polymer–alloy hybrid layer on lithium metal for dendrite-free anodes. Treated lithium anodes exhibited outstanding cycling performance in Li–S and Li–LiFePO4 full cells and retained good electrochemical performance after exposure to humid air (see picture).

Abstract

Lithium-metal anodes are recognized as the most promising next-generation anodes for high-energy-storage batteries. However, lithium dendrites lead to irreversible capacity decay in lithium-metal batteries (LMBs). Besides, the strict assembly-environment conditions of LMBs are regarded as a challenge for practical applications. In this study, a workable lithium-metal anode with an artificial hybrid layer composed of a polymer and an alloy was designed and prepared by a simple chemical-modification strategy. Treated lithium anodes remained dendrite-free for over 1000 h in a Li–Li symmetric cell and exhibited outstanding cycle performance in high-areal-loading Li–S and Li–LiFePO4 full cells. Moreover, the treated lithium showed improved moisture stability that benefits from the hydrophobicity of the polymer, thus retaining good electrochemical performance after exposure to humid air.
