Rechargeable aqueous Zn-ion batteries (ZIBs) have sparked substantial attention as prospective Lithium-ion battery replacements because of its low cost, large theoretical capacity, low redox potential, and environmental friendliness. However, various disadvantages associated with Zn metal anodes, including dendritic formation, hydrogen evolution, and corrosion, significantly limit ZIB performance. To solve the aforementioned issues and improve the reversibility of Zn anodes during long-term cycling, bimodal BaTiO3 particles have been produced as increasing dielectric characteristics in artificial layers on Zn-metal. In an external electric field, the bimodal BaTiO3 layer works as an electric polarizer, forcing the Zn ions to migrate successively towards the Zn anode side. Furthermore, the mechanical property reduces the volume fluctuations between the BaTiO3 artificial layer and the Zn-metal.
