主 题:anti-corrosion aqueous zinc ion battery interfacial protective layer metal passivation technique reconstruction of surface crystal plane
摘 要:For the aqueous Zn-ion battery,dendrite formation,corrosion,and interfacial parasitic reactions are major issues,which greatly inhibits their practical *** to develop a method of Zn construction or treatment to solve these issues for Zn anodes are still great ***,a simple and cheap metal passivation technique is proposed for Zn anodes from a corrosion science *** to the metal anticorrosion engineering,the formed interfacial protective layer in a chemical way can sufficiently solve the corrosion ***,the proposed passivity approach can reconstruct Zn surface-preferred crystal planes,exposing more(002)planes and improving surface hydrophilicity,which inhibits the formation of Zn dendrites and hydrogen evolution *** expected,the passivated Zn achieves outstanding cycling life(1914 h)with low voltage polarization(40 mV).Even at 6 mA cm^(−2) and 3 mA h cm^(−2),it can achieve stable Zn deposition over 460 *** treated Zn anode coupled with MnO_(2) cathode shows prominently reinforced full batteries service life,making it a potential Zn anode candidate for excellent performance aqueous Zn-ion *** proposed passivation approach provides a guideline for other metal electrodes preparation in various batteries and establishes the connections between corrosion science and batteries.
