摘要

A LLZTO-2wt.% Li 3 OCl composite solid electrolyte (LC) layer was attached to the surface of a Limetal electrode through a glass-fiber-paper (GF)-supported method to form a stable in situ reactioninterfacial layer between the Li metal anode and an organic liquid electrolyte in Li metal batteries. TheLi metal anode modified by GF-LC showed excellent cycling stability in a Li metal symmetric battery(over 1100 h stable cycles at 1 mA cm -2 / 1 mA h cm -2 with less corrosion of Li metal anode) and Li-Cu battery (over 300 h cycles at 1 mA cm -2 / 1 mA h cm -2 with Coulombic efficiency of 99.0%). Thesuperior stability and dendrite-free mechanism of the GF-LC-modified Li metal anode is related to thereduced direct contact area and less corrosive side reactions between the organic electrolyte and the Limetal anode. Based on the excellent stability of the GF-LC-modified Li metal anode, a Li-S batterywas assembled to research the effect of the GF-LC modified Li metal anode on cycling stability.Compared with Li-S batteries modified by pristine and GF-modified Li metal anodes, the GF-LC-modified Li-S battery showed better cycling stability and longer cycling life.
