Abstract A stable interfacial design bridging Li metal and sulfide solid electrolytes is imperative for deploying practical all‐solid‐state batteries. Despite the extensive exploration of interlayer materials, including inorganic substances, lithiophilic metals, their composites, a comprehensive understanding stability chemo‐mechanical evolution, particularly those influenced by cell fabrication processes, remains unexplored. Herein, it meticulously investigate formation evolution LiF, Mg, conversion‐type multicomponent MgF 2 ultrathin interlayers, each fabricated via thermal evaporation deposition. Unexpectedly, LiF Mg fail to enhance performance, with notably susceptible external pressures during fabrication, leading serious current constriction, while deposition results in Li‐rich solution. Remarkably, coatings demonstrate substantially superior performance both Li|Li 6 PS 5 Cl|Li symmetric cells (up 2000 h) LiNi 0.70 Co 0.15 Mn O |Li full‐cells (82% capacity retention after 800 cycles) at 30 °C. These are attributed in‐situ x nanograins through conversion reaction, which, repeated cycling, maintains fixed position interface ensuring uniform + flux. Supported analyses, these findings highlight pivotal role interlayers mitigating side reactions preventing penetration.
