Anion-mediated regulation of open metal sites in metal–organic framework materials or high-performance solid-state electrolytes
In this study, a Cu-MOF was successfully synthesized, and the coordination behavior between its open metal sites (OMSs) and various anions was systematically investigated. It was determined that the NO<sub>3</sub><sup>-</sup> anion exhibits the most effective coordination with the Cu<sup>2+</sup> sites. This optimal interaction endows the resulting LiNO<sub>3</sub>@Cu-MOF with superior electrochemical properties: an ionic conductivity of 1.19 × 10<sup>-3</sup> S cm<sup>-1</sup>, a lithium-ion transference number of 0.69, and stable lithium plating/stripping for 1600 hours at 0.2 mA cm<sup>-2</sup>. This work elucidates the profound role of OMSs in regulating anion coordination and provides a novel design strategy for high-performance, MOF-based solid-state electrolytes.
