摘要

金属有机框架(MOFs)因其结构多样性和多孔性而被视为潜在的固态电解质(SSE)材料。在 MOF 的阴离子框架中加入锂离子并实现单离子传输是提高 SSE 材料离子导电性能的有效方法。本文通过离子交换策略合成了一种在晶格孔隙中含有锂离子的各向离子MOF(Li+[Cu-BTC]-),该MOF在宽温度范围内表现出优异的锂离子传导性能(离子电导率:-40至100 ℃温度范围内为0.11-2.96 × 10-3 S cm-1)。在阴离子金属有机框架内注入 Li+ 的策略为探索先进的 SSE 提供了新的机遇。

Enhancing the performance of ionic conductivity for solid-state electrolytes: an effective strategy of injecting lithium ions within anionic metal–organic frameworks†

Metal–organic frameworks (MOFs) are considered as potential solid-state electrolyte (SSE) materials due to their structural diversity and porosity. Adding lithium ions into the anionic frameworks of MOFs and then realizing single-ion transport is an efficient way to enhance the performance of ionic conductivity of SSE materials. Herein, an ionotropic MOF (Li+[Cu-BTC]) with lithium ions in the pores of the lattice was synthesized through an ion exchange strategy, which exhibits outstanding lithium ionic conducting properties over a wide temperature range (ionic conductivity: 0.11–2.96 × 10−3 S cm−1 in the temperature range of −40 to 100 °C). The strategy of injecting Li+ within anionic metal–organic frameworks provides a new opportunity for exploring advanced SSEs.
