Constructing composite solid electrolytes (CSEs) integrating the merits of inorganic and organic components is a promising approach to developing high-performance all-solid-state lithium metal batteries (ASSLMBs). CSEs are now capable achieving homogeneous fast Li-ion flux, but how escape trade-off between mechanical modulus adhesion still challenge. Herein, strategy address this issue proposed, that is, intercalating highly conductive, homogeneous, viscous-fluid ionic conductors into robust coordination laminar framework construct electrolyte with conduction (LSE-HFC). A 9 µm-thick LSH-HFC, in which poly(ethylene oxide)/succinonitrile adsorbed by metal-organic nanosheets as building blocks, used here an example determine validity. The transfer mechanism verified works across entire LSE-HFC, facilitates flux low migration energy barriers, endowing LSE-HFC high conductivity 5.62 × 10
