| 英文摘要 | Aqueous zinc metal batteries (ZMBs) are vital to potable electronics and electric energy infrastructures because of their high energy conversion efficiency, high energy density, and environmental friendliness. However, rampant zinc dendrite growth and side reactions on the Zn anode seriously impede the practical application of ZMBs. In this work, morpholine-crosslinked polyacrylamide hydrogel electrolytes (ploy(acrylamide), 6m-PAM) are successfully developed to simultaneously regulate solvation shell to suppress side reactions and homogenize Zn2* ion migration for dendrite-free ZMBs. Notably, the 6m- PAM electrolyte exhibits excellent mechanical strength of 50.6 kPa, high Zn2* ion conductivity of 52 mS cm 1 at room temperature, and fast self-healing ability, providing stable and adaptable electrolyte-anode interfaces. Experimental and theoretical calculation results reveal that Zn2*-N (morpholine) coordination interaction effectively reshapes the primary solvation shell of Zn2*, suppressing the activity of free water and Zn dendrites. As a result, the 6m-PAM electrolyte endows symmetric zinc cells with a long-term cycling life of 2000 h at 7.5 mA cm 2 . Notably, Zn/Polyaniline (PANI) batteries equipped with 6m-PAM electrolytes also exhibit a high capacity of 124 mA h g 1 at 1 A g 1 and a long cycling life of 4000 times with a high-capacity retention of 98.3%. This functional crosslinked hydrogel electrolyte paves a new way to construct durable dendrite-free ZMBs. (c) 2024 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
