主　　题：Aqueous Zn ion battery Bi_(2)S_(3) Good stability 

摘      要：Aqueous Zn ion batteries(ZIBs)are promising in energy storage due to the low cost,high safety,and material *** development of metal oxides as the cathode for ZIBs is limited by the strong electrostatic forces between O2−and Zn2+which leads to poor cyclic ***,Bi2S3 is proposed as a promising cathode material for rechargeable aqueous *** cyclic stability and fast diffusion of Zn2+is ***,the layered structure of Bi2S3 with the weak van der Waals interaction between layers offers paths for diffusion and occupancy of Zn2+.As a result,the Zn/Bi2S3 battery delivers high capacity of 161 mAh g−1 at 0.2 A g−1 and good cycling stability up to 100 cycles with ca.100%*** battery also demonstrates good cyclic performance of ca.80.3%over 2000 cycles at 1 A g−*** storage mechanism in the Bi2S3 cathode is related to the reversible Zn ion intercalation/extraction reactions and the capacitive *** work indicates that Bi2S3 shows great potential as the cathode of ZIBs with good performance and stability.
