Study on the Structure-effect Relationship of Cu-Zn Anode in Zinc Ion Battery
Aqueous zinc ion batteries(AZIBs)have the advantages of high safety,low cost and green,etc.In AZIBs,the anode zinc foil material is one of the key factors to improve the cycle life of zinc ion batteries.In this paper,a more stable copper-zinc composite negative electrode material was prepared by electrochemical deposition method,and the button cell can be stably operated for 100 cycles at 100％high DOD by experimental test.The results show that the Cu-Zn composite anode effectively improves the electron transfer rate and prevents the growth of dendrites on the surface of the zinc anode,and this work provides theoretical support for the optimisation of anode materials for zinc ion batteries.
