摘要

Abstract

Metal-organic frameworks (MOFs) are becoming more and more popular as the fillers in polymer electrolytes in recent years. In this study

a series of MOFs (NH

-MIL-101(Fe)

MIL-101(Fe)

activated NH

-MIL-101(Fe) and activated MIL-101(Fe)) were synthesized and added to PEO-based solid composite electrolytes (SCEs). Furthermore

the role of the —NH

groups and open metal sites (OMSs) were both examined. Different ratios of MOFs

polymers were also studied by the electrochemical characterizations. At last

we successfully designed a novel solid composite electrolyte containing activated NH

-MIL-101(Fe)

PEO

LiTFSI and PVDF for the high-performance all-solid-state lithium-metal batteries. This work might provide new insight to understand the interactions between polymers and functional groups or OMSs of MOFs better.
