The thickness of solid-state electrolytes (SSEs) significantly affects the energy density and safety performance of all-solid-state lithium batteries. However, a sufficient understanding of the reactivity toward lithium metal of ultrathin SSEs (<100 μm) based on NASICON remains lacking. Herein, for the first time, a self-standing and ultrathin (70 μm) NASICON-type Li1.5Al0.5Ge1.5(PO4)3 (LAGP) electrolyte via a scalable solution process is developed, and X-ray photoelectron spectroscopy reveals that changes in LAGP at the metastable Li-LAGP interface during battery operation is temperature dependent. Severe germanium reduction and decrease in LAGP particle size are detected at the Li-LAGP interface at elevated temperature. As a result, oriented plating of lithium metal on its preferred (110) face occurs during in situ X-ray diffraction cycling.
