A functionalized metal organic framework-laden nanoporous polymer electrolyte for exceptionally stable lithium electrodeposition

A nanoporous all-solid-state MOF-laden polymer electrolyte that is simply mediated by an electronic effect shows remarkably high lithium electrodeposition stability of hundreds of charge-discharge cycles and over 1500 operating hours, while maintaining a very small voltage polarization. This result is a significant improvement relative to conventional PEO and, when used in an all-solid-state battery (ASSB), this electrolyte enabled enhanced cycle life. This new all-solid-state electrolyte shows a promising rational design for the emerging microporous polymeric materials as novel SPEs in ASSBs.
