Stable and dendrite-free Zn anode with artificial desolvation interface layer toward high-performance Zn-ion capacitor
文献摘要：
Aqueous Zn-based energy storage devices possess tremendous advantages,such as low cost,high safety,and competitive energy density,due to employing a Zn metal anode and aqueous electrolyte.However,the cycling stability and rate ability of a Zn anode are hindered by Zn dendrite growth and sluggish ion transfer in the electrode/electrolyte interface.Herein,the interfacial properties of Zn anodes are improved through the introduction of a silver(Ag)protective layer,which facilitates uniform Zn deposi-tion and regulates Zn ion transport.As a result,Ag-coated Zn anodes display stable cycling performance(600 h at 1 mA cm-2)and low overpotential(150 mV at 50 mA cm-2 after 2000 cycles).The Ag layer in situ electrochemically converts into an AgZn3 layer and promotes Zn ion desolvation and three-dimensional diffusion processes.Moreover,a Zn-ion capacitor assembled with an Ag-coated Zn anode and active carbon cathode shows a capable cycling lifespan and rate performance.This study provides a feasible strategy for constructing a stabilized and dendrite-free Zn anode for the development of high-performance Zn-based energy storage devices.
