Solid-state batteries (SSBs) hold immense potential for improved energy density and safety compared to traditional batteries. However, existing solid-state electrolytes (SSEs) face challenges in meeting the complex operational requirements of SSBs. This study introduces a novel approach address this issue by developing metal-organic framework (MOF) with customized bilayer zwitterionic nanochannels (MOF-BZN) as high-performance SSEs. The BZN consist rigid anionic MOF channel chemically grafted soft multicationic oligomers (MCOs) on pore wall. design enables selective superionic conduction, MCOs restricting movement anions while coulombic interaction between promoting dissociation Li+ . MOF-BZN exhibits remarkable conductivity (8.76 × 10-4 S cm-1 ), high transference number (0.75), wide electrochemical window up 4.9 V at 30 °C. Ultimately, SSB utilizing flame retarded achieves an impressive specific 419.6 Wh kganode+cathode+electrolyte-1 under constrained conditions cathode loading (20.1 mg cm-2 ) limited lithium metal source. constructed MOFs present pioneering strategy advanced SSEs highly efficient

Composite-polymer-electrolytes (CPEs) embedded with advanced filler materials offer great promise for fast and preferential Li+ conduction. The surface chemistry determines the interaction electrolyte molecules thus critically regulates behaviors at interfaces. Herein, we probe into role of electrolyte/filler interfaces (EFI) in CPEs promote conduction by introducing an unsaturated coordination Prussian blue analog (UCPBA) filler. Combining scanning transmission X-ray microscope stack imaging studies first-principle calculations, is revealed only achievable a chemically stable EFI, which can be established Co-O UCPBA to circumvent side reactions. Moreover, as-exposed Lewis-acid metal centers efficiently attract Lewis-base anions Li salts, facilitates disassociation enhances its transference number (tLi+). Attributed these superiorities, obtained realize high room-temperature ionic conductivity up 0.36 mS cm-1 tLi+ 0.6, enabling excellent cyclability lithium electrodes over 4,000 h as well remarkable capacity retention 97.6% 180 cycles 0.5 C solid-state lithium-sulfur batteries. This work highlights crucial EFI developing highly conductive high-performance

Solid polymer electrolytes (SPEs) for lithium metal batteries have garnered considerable interests owing to their low cost, flexibility, lightweight, and favorable interfacial compatibility with battery electrodes. Their soft mechanical nature compared solid inorganic give them a large advantage be used in pressure solid-state batteries, which can avoid the cost weight of cages. However, application SPEs is hindered by relatively ionic conductivity. In addressing this limitation, enormous efforts are devoted experimental investigation theoretical calculations/simulation new classes. Recently, metal-organic frameworks (MOFs) been shown effective enhancing ion transport SPEs. mechanisms Li
