Aqueous zinc-ion batteries (AZIBs) have gradually become the focus of energy storage research due to high security and low cost. However, inferior reversibility of Zn metal anodes due to severe side reactions and zinc dendrites often leads to unsatisfactory battery performance. Herein, a BiOIO 3 nanosheets modified glass fiber (GF) separator (denoted as BiOIO 3 @GF) was developed to tailor ion transport, thereby reinforcing Zn metal anode. In addition to well filling within the pores of GF, remarkable properties of spontaneous polarization effe...
