Abstract Sulfide electrolytes are considered the most promising technique for all‐solid‐state lithium–sulfur batteries (ASLSBs) due to relatively high ionic conductivity and superior chemical compatibility with composite sulfur cathodes. However, cathodes based on sulfide feature large volume expansion, unstable interfacial contact, inherent insulating nature, which impedes practical application of ASLSBs. Therefore, a systematic design cathode side ASLSBs is crucial ensuring well‐contacted, electrochemically stable cathode–electrolyte interface, an effective ion‐electron transfer network. Here, comprehensive discussion latest strategies will be delivered, highlighting their effectiveness in improving performances First, major challenges including slow oxidation kinetics significant expansion dissected. Then, focus shifted degradation processes at interface between electrolyte. Subsequently, improvement stability by structural modulation elaborated. Finally, progress, we present new perspective constructing efficient transport network cathode‐electrolyte offers insights directions achieving future.

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 anode leads continuous interfacial reactions dendrites growth, which severely hinders practical applications. We propose an electron localization strategy by modulating d-p orbital hybridization within PS4 tetrahedral structure of Li6PS5Cl through homogeneous incorporation yttrium (Y) oxygen (O). The introduction Y strengthens Madelung energy with sulfur (S) atom induces electronic S atom, suppresses interaction tetrahedron. air-stability is also enhanced due introduction. Furthermore, situ formation Li2O interphase acts as a protective barrier, synergistically mitigating Li6PS5Cl. Li symmetric cell modulated electrolyte achieves stable plating/stripping for over 4800 h. LiCoO2/Li-In electrode display remarkable long cycle performance 100% retention after 1300 cycles at 0.5 C. This study presents distinct that employs driven achieve ultrastable interface sulfide-based batteries.

ABSTRACT Solid‐state electrolyte (SSE) is a potential way to solve the safety problems of lithium metal batteries (LMBs), and Li 6.5 La 3 Zr 1.5 Ta 0.5 O 12 (LLZTO) one most extensive research SSEs due its good air stability wide electrochemical window. However, residual alkali on LLZTO surface limits application with polyvinylidene difluoride (PVDF)‐contained binders, uncontrollable dendrites growing between grain boundaries particles would lead rapid capacity fading short circuit risk. Herein, by in situ coating PO 4 (LPO) (LLZTO@LPO) evenly, neutralized pH value reduced 8.84. The modified can be mixed PVDF solution shows fluidity without cross‐linking reaction, making subsequent ceramic separator feasible. LLZTO@LPO polyethylene (PE) achieve 1400 h (115% increase) stable cycling under 1 mA cm −2 current density Li∥Li symmetrical cell 80% retention after 260 cycles (NCM622‐Li coin mAh loading). Furthermore, SSE pellets were prepared assembled cell. critical (CCD) result increases from 0.7 1.6 owing that LPO effectively inhibits formation through boundaries. This work provides strategy for fabricating layer improve LMBs.
