Recent advances of organometallic complexes for rechargeable batteries

摘要

Organometallic complexes (OMCs) consisting of organic and metal active moieties have shown immense potential for application in batteries. The diverse structure, rich porosity, and unique charge centers of OMCs enable them to be functional in batteries. In this review, we first classify OMCs into metal-organic frameworks, porphyrin, phthalocyanine, and ferrocene etc. Then, we mainly focus on the recent progress of each type of OMCs in rechargeable batteries. They can serve as electrode or electrolyte materials in a variety of battery systems such as Li, Na, Zn, Li-S, Li-O-2, and redox flow batteries. The performance enhancements in these batteries are closely related to the structures and properties of OMCs. In-depth analyses of the structure-performance relationships is provided. At the end, perspectives on the opportunities and challenges of these materials are given. This review would endow more inspiration on the development of OMCs for advanced batteries.
