摘　　要：The rising demand for high-energy-density storage solutions has catalyzed extensive research into solid-state lithiumoxygen(Li-O_(2))batteries.These batteries offer enhanced safety,stability,and potential for high energy density,addressing limitations of conventional liquid-state designs,such as flammability and side reactions under operational conditions.This perspective reviews the latest advancements in solid-state Li-O_(2)batteries,focusing on performance metrics such as cycle life,areal capacity,and current density.Material selections from recent studies are examined.Key reporting practices,such as liquid content,operation temperature,availability of differential electrochemical mass spectrometry results,and reporting completeness on loading information are summarized.Additionally,relationships among various performance metrics are explored.Despite significant progress,solid-state Li-O_(2)batteries continue to face limitations with low current densities and limited cycle capacities,indicating that existing materials and designs have yet to fully exploit the technology’s theoretical potential.This analysis highlights areas for future research,particularly in stability and interfacial engineering,to bridge the gap toward commercially viable,high-energy-density solidstate Li-O_(2)batteries.
