Summary: Anode-free all-solid-state batteries (AFASSBs) simplify the manufacturing process by eliminating the lithium anode. This study investigates the effects of different solid electrolytes (SEs) on AFASSBs without stack pressure. The results demonstrate that argyrodites enhance Li plating/stripping, while other SEs degrade quickly. Superionic halogen-rich Li-argyrodites, specifically Li5.5PS4.5Cl1.5, show improved capacity and cyclability, indicating their benefit for AFASSBs. The elimination of the initial Li nucleation reaction further enhances the interfacial stability, and the combination of Li5.5PS4.5Cl1.5 and Ag-C achieves the highest coulombic efficiency.

Summary: Amorphous sulfides are promising solid electrolyte materials due to their deformability and Li-ion conductivity. However, the complex atomic structure of these materials poses challenges in tuning their properties. In this study, structural mapping of glassy sulfide solid electrolytes composed of different anion clusters was performed using X-ray-based pair distribution function (PDF) and reverse Monte-Carlo (RMC) methods, showing potential for tuning Li-ion conductivity. A new glassy sulfide with a mixed anion framework of two halogens (Br and I) showed the highest Li-ion conductivity reported for any glass sulfide. Molecular dynamics simulations confirmed that flexible coordination contributed to the superior Li-ion conductivity.
