Solid‐state electrolytes are the key to the development of lithium‐based batteries with dramatically improved energy density and safety. Inspired by ionic channels in biological systems, a novel class of pseudo solid‐state electrolytes with biomimetic ionic channels is reported herein. This is achieved by complexing the anions of an electrolyte to the open metal sites of metal–organic frameworks (MOFs), which transforms the MOF scaffolds into ionic‐channel analogs with lithium‐ion conduction and low activation energy. This work suggests the emergence of a new class of pseudo solid‐state lithium‐ion conducting electrolytes.

在金属有机框架中利用仿生离子通道创建锂离子电解质

固态电解质是锂基电池发展的关键，它大大提高了能量密度和安全性。受生物系统中离子通道的启发，本文报道了一类新型的具有仿生离子通道的伪固态电解质。这是通过将电解质的阴离子与金属有机骨架（MOF）的开放金属位点络合而实现的，这会将MOF支架转变为具有锂离子传导性和低活化能的离子通道类似物。这项工作表明出现了新型的伪固态锂离子导电电解质。
