A multi-functional protective material with atomically dispersed zincophilic sites enabling long-life zinc anodes.

ABSTRACT: Parasitic side reactions and the formation of zinc dendrites in aqueous solutions severely hinder the practical application of Zn metal anodes. Carbon materials with high electrical conductivity and mechanical robustness are promising protective materials for Zn anodes. However, the zincophobic nature of carbon materials impedes the cycling stability of zinc-ion batteries. Herein, a versatile design strategy is proposed utilizing carbon doped with single atoms with atomically dispersed zincophilic sites as a multi-functional protective material for high-performance zinc anodes. Taking bismuth-single-atom-doped carbon (Bi SAs) as an example, density functional calculations verify that the introduction of bismuth single atoms can enhance zincophilicity, promote robust adhesion to zinc foil,
