Solid-state lithium metal batteries (SSLMBs) are drawing worldwide attention as a next-generation technology that promises higher energy density and greater safety than today’s lithium-ion batteries. Among the most promising candidates for their solid electrolytes is the garnet-type oxide Li₇La₃Zr₂O₁₂ (LLZO), which combines high ionic conductivity with strong chemical stability. However, fabricating thin, dense, and defect-free ceramic membranes has long posed a challenge, limiting large-scale application.
