| 1 | The electrolyte comprising more robust water and superhalides transforms Zn-metal anode reversibly and dendrite-free显示文摘A great challenge for all aqueous batteries,including Zn-metal batteries,is the parasitic hydrogen evolution reaction on the low-potential anode.Herein,we report the formula of a highly concentrated aqueous electrolyte that mitigates hydrogen evolution by transforming water molecules more inert.The electrolyte comprises primarily ZnCl_(2) and LiCl as an additive,both of which are inexpensive salts.The O-H covalent bonds in water get strengthened in a chemical environment that has fewer hydrogen bonding interactions and a greater number of Zn-Cl superhalides,as suggested by integrated characterization and simulation.As a result,the average Coulombic efficiency of zincmetal anode is raised to an unprecedented>99.7%at 1mA cm^(−2).In the new electrolyte,the plating/stripping processes leave the zinc-metal anode dendrite-free,and the zinc-metal anode delivers stable plating/stripping cycles for 4000 hours with an areal capacity of 4 mAh cm^(−2) at 2mA cm^(−2).Furthermore,the high Coulombic efficiency of zinc-metal anode in the ZnCl_(2)-LiCl mixture electrolyte is demonstrated in full cells with a limited anode.The V_(2)O_(5)·H_(2)O||Zn full cell with an N/P mass ratio of 1.2 delivers a stable life of more than 2500 cycles,and the LiMn_(2)O_(4)||Zn hybrid cell with an N/P mass ratio of 0.6 exhibits 1500 cycles in its stable life. | Chong Zhang Woochul Shin Liangdong Zhu Cheng Chen Joerg C.Neuefeind Yunkai Xu Sarah I.Allec Cong Liu Zhixuan Wei Aigerim Daniyar Jia‐Xing Jiang Chong Fang P.Alex Greaney Xiulei Ji | 2021 | Carbon Energy2021，3，2： | 3 |
