8.5 <b>µ</b> m‐Thick Flexible‐Rigid Hybrid Solid–Electrolyte/Lithium Integration for Air‐Stable and Interface‐Compatible All‐Solid‐State Lithium Metal Batteries (Adv. Energy Mater. 24/2022)

Li Metal Anodes In article number 2200368, Xinran Wang, Ying Bai, Chuan Wu and co-workers develop air-stable and interface-compatible PEGMA-Li1.5Al0.5Ge1.5(PO4)3-lithium integration, taking advantage of a record-breaking thin layer, sufficiently high ionic conductivity, and flexible-rigid mechanical properties that synergistically solve problems encountered by all solid-state lithium metal batteries (ASSLMBs). This first-of-its-kind integrated structure provides a new paradigm to assemble ASSLMBs in ambient condition, paving the way toward ASSLMBs with high safety and high energy density.
