摘要	Sulfide solid electrolytes (SSEs) exhibit exceptional ionic conductivity and processing advantages for all-solid-state lithium metal batteries (ASSLBs), but their commercialization is constrained by ambient hydrolysis-induced H2S generation and lithium dendrite formation at electrolyte/anode interfaces. Herein, a Ce/O co substitution strategy is employed to synthesize argyrodite-type Li5.4+xP1-xCexS4.4 2xO2xCl1.6 (0 ≤ x ≤ 0.05) solid electrolytes. The substitution of P5+ with Ce4+ and S2- with O2- in the PS43- structure forms stable CeS44- and PS3O3- groups and enhances structural integrity. Simultaneously, the incorporation of Ce4+ expands the lattice spacing and facilitates Li+ transport. Optimized Li5.42P0.98Ce0.02S4.36O0.04Cl1.6 electrolyte exhibits superior ionic conductivity (7.13 mS cm-1) and excellent air stability (H2S emission: 0.36 cm3 g-1 after 30 minutes in 30% RH). The electrolyte demonstrates an enhanced critical current density of 1.3 mA cm-2 and stable lithium plating/stripping over 5000 h at 0.1 mA cm−2. ASSLBs with LiNbO3@NCM622 cathodes deliver an initial discharge capacity of 128.19 mAh g-1 and 99.49% retention after 300 cycles. This work provides a Ce/O co-substitution strategy for designing high performance SSEs toward practical all-solid-state lithium metal batteries.
