近期,由葡萄京APP教师魏涛第一作者和通讯作者,研究生王志孟为第二作者等的研究成果“Activated metal-organic frameworks (a-MIL-100 (Fe)) as fillers in polymer electrolyte for high-performance all-solid-state lithium metal batteries”在《Materials Today Communications》上发表。

 

论文简介如下:

As a common filler in polymer electrolytes, Metal-organic frameworks (MOFs) has been studied extensively in recent years. In this study, we propose a novel solid composite electrolytes (SCEs) based on PEO/LiTFSI/a-MIL-100 (Fe)/PVDF by using a straightforward solution-casting method. Unactivated and activated MIL-100 (Fe) (a-MIL-100 (Fe)) as the fillers were compared, and the interactions of functional groups of unactivated MIL-100 (Fe) and a-MIL-100 (Fe) with anions of electrolyte salts through Lewis acid-base interaction are studied with density functional theory (DFT) calculations. The influences of different a-MIL-100 (Fe) contents on electrochemical performances were also examined. The Li/SCEs/LiFePO4 cell displayed high average discharge capacities of 161.8 mAh g?1, 166.8 mAh g?1, 158.9 mAh g?1, 146.2 mAh g?1 and 92.6 mAh g?1 at the rate of 0.1, 0.2, 0.5, 1 and 2 C at 60 , respectively, without liquid electrolytes. This work might provide new insight into the role of activated MOFs fillers in polymer electrolytes..
