Building a multifunctional Cu 2 Se@biomass carbon composite interfacial layer on a zinc anode for stable aqueous zinc-ion batteries

Cu 2 Se@BC was constructed to improve the structural stability of Zn anodes. It can induce the preferential orientation of zinc ions on the Zn (002) crystal plane. The AZIBs assembled with the Cu 2 Se@BC–Zn anode showed good electrochemical performance.
