A prelithiated Sn (LiSn) anode was developed for sulfide-based all-solid-state Li batteries (ASSLBs), demonstrating high compatibility with LiPSCl sulfide electrolyte. The LiSn|NCM811 cell achieved 163 mA h g capacity (0.1C) and 91% retention after 650 cycles (1C). Prelithiation compensated Li loss and mitigated volume expansion, enabling high-performance ASSLBs.

Achieving high ionic conductivities in solid state electrolytes is crucial for the development of efficient all-solid-state-batteries. Considering future availability and sustainability, sodium materials hold promises for an alternative for lithium materials in all-solid-state batteries, due to the higher abundance. Here we report on a sodium phosphide ion conductor Na8SnP4 with a conductivity of 0.

All-solid-state lithium-sulfur batteries (ASSLSBs) using inorganic solid-state electrolytes can effectively alleviate the polysulfide shuttle effect in liquid electrolytes and improve the energy density. However, the electrochemical window of sulfide-based catholytes in composite cathodes is relatively narrow, which makes the evaluation of electrochemical performance of sulfur cathodes in ASSLSBs complicated. The decomposition of the sulfide catholytes increases the interfacial resistance, thus reducing the battery cycle life.

Argyrodite-based sulfide electrolytes have received considerable attention in all-solid-state lithium metal batteries owing to their high ionic conductivity and good mechanical property. However, the reactivity between sulfide electrolytes and lithium anode leads to continuous interfacial reactions and dendrites growth, which severely hinders their practical applications. We propose an electron localization strategy by modulating the d-p orbital hybridization within the PS tetrahedral structure of LiPSCl through homogeneous incorporation of yttrium (Y) and oxygen (O).

Argyrodites are among the most promising sulfide-based solid electrolytes (SEs) due to their high ionic conductivity and ductility. However, the poor atmospheric stability of sulfide-based SEs caused by the side reaction with moisture, which generates toxic HS gas and degrades its high ionic conductivity and low electronic conductivity, has limited the commercialization of ASSBs. Herein, the preparation of sulfide-based SEs consisting of a LiPSCl (LPSCl) core and fluoride-rich LPSCl shell are described using a facial fluorine treatment following an annealing process to improve atmospheric stability.
