Open frameworks materials towards stable aqueous zinc-ion batteries
摘要
Aqueous zinc-ion batteries (AZIBs) have drawn much attention due to their low cost, environmental friendliness and safety. However, the formation of zinc dendrites remains a central challenge, leading to battery short-circuiting and reduced the cycle life. Open Frameworks Materials (OFMs), mainly including covalent organic frameworks (COFs) and metal–organic frameworks (MOFs), demonstrated great potential for electrochemical energy storage and conversion systems. In AZIBs, OFMs with ordered porous structures and tunable chemical functionalities have been extensively applied in the electrodes, separators, electrolytes and so forth. Previous researches have shown that OFMs could effectively regulate ionic transport behavior, inhibit the dendritic growth, and enhance the cycle stability and rate performance of AZIBs. A comprehensive discussion on the roles of OFMs in AZIBs is of great significance for the development of aqueous secondary batteries. In this review, the advantages of OFMs are discussed firstly. Then, the applications of OFMs for cathodes, anodes, separators as well as electrolytes and solid electrolyte interphase are reviewed in detail. Lastly, some future perspectives of OFMs for AZIBs are proposed. This study may provide some inspiration for the development of advanced aqueous energy storage and conversion devices.
