dc.description.abstractAnode-free all-solid-state batteries (AFASSBs) have the advantages of a simplified manufacturing process because of the absence of a lithium anode. Here, we systematically investigate the effect of various solid electrolytes (SEs) on the electrochemical properties of AFASSBs without stack pressure. The results show that argyrodites promote Li plating/stripping, whereas other SEs are rapidly degraded. Interestingly, Li5.5PS4.5Cl1.5, with an ionic conductivity of 9.8 mS cm(-1), provides better capacity and cyclability than Li6PS5Cl (4.3 mS cm(-1)), indicating that superionic halogen-rich Li-argyrodites are beneficial for AFASSBs. A model study based on a prelithiated current collector reveals that the elimination of the initial Li nucleation reaction further improves the interfacial stability of Li5.5PS4.5Cl1.5. Consequently, the combination of Li5.5PS4.5Cl1.5 and Ag-C achieves the highest coulombic efficiency owing to the synergistic effect of a chlorine-rich SE and an Li-alloying interlayer. These findings show the potential of utilizing superionic halogen-rich Li-argyrodites and alleviating the Li nucleation overpotential in AFASSBs.-
