Abstract

The development of intercalation anodes with high capacity is key to promote the progress of "rocking-chair" Zn-ion batteries (ZIBs). Here, layered BiOI is considered as a promising electrode in ZIBs due to its large interlayer distance (0.976 nm) and low Zn2+ diffusion barrier (0.57 eV) obtained by density functional theory, and a free-standing BiOI nanopaper is designed. The process and mechanism of Zn(H2O)n2+ insertion in BiOI are proved by ex situ X-ray diffraction, Raman, and X-ray photoelectron spectroscopy. The suitable potential (0.6 V vs Zn/Zn2+), high reversible capacity (253 mAh g-1), good rate performance (171 mAh g-1 at 10 A long cyclic life (113 mAh g-1 after 5000 cycles at 5 A g-1), and dendrite-free operation of BiOI nanopaper prove its potential as a superior anode. When it is coupled with Mn3O4 cathode, the quasi-solid-state battery exhibits a high initial capacity of 149 mAh g-1 (for anode) and a good capacity retention of 70 mAh g-1 after 400 cycles. The self-assembled flexible battery also shows stable charge-discharge during the cyclic test. This work shows the feasibility of BiOX anode for dendrite-free ZIBs.
