Synthesis and characterization of argyrodite solid electrolytes for all-solid-state Li-ion batteries

Li₆PS₅X (X = Cl, Br, I) argyrodites possess high ionic conductivity but with rather scattered values due to various processing conditions. In this work, Li₆PS₅X solid electrolytes were prepared by solid-state sintering or mechanical alloying and optimized with or without excess Li₂S....

Lithium halide coating as an effective intergrain engineering for garnet-type solid electrolytes avoiding high temperature sintering

Garnet-type Li₇La₃Zr₂O₁₂ solid electrolytes were commonly prepared by two steps solid-state reaction method, which undergoes high temperature over 1000 °C and thus inevitable for lithium volatilization and formation of secondary phases. Here, we propose a new intergrain architecture engineering of a...
