A tetraphenylborate-based anionic metal-organic framework as a versatile solid electrolyte for fast Li⁺, Na⁺, K⁺, Mg²⁺, Ca²⁺, and Zn²⁺ transportation.

ABSTRACT: Tetraphenylborate (BPh₄ ^-) has been widely employed in the field of electrolytes and displayed better ionic conductivities in polymer solid-state Li⁺ conductors. However, the fabrication of tetraphenylborate monomers into metal-organic frameworks (MOFs) and the exploration of their potential in solid-state electrolytes have never been reported. In this work, carboxylic acid functionalized lithium tetraphenylborate was purposefully synthesized and employed to construct an anionic MOF as a solid electrolyte. The counter cation Li⁺ was encapsulated into the anionic channel to become the free mobile charge carrier that produced a lithium-ion solid electrolyte with outstanding ion conductivity (2.75 × 10^-3 S cm^-1 at 25 °C), an im
