Recent advances in MOFs/MOF derived nanomaterials toward high-efficiency aqueous zinc ion batteries

Aqueous zinc ion batteries (AZIBs) with cost-effectiveness, intrinsic safety, environmental benignity, easy manufacturing and high specific and volumetric capacity are considered one of alternatives with the best prospects for next-generation secondary batteries. However, current AZIBs are still difficult to meet large-scale commercial applications, constrained by major challenges from the cathode, electrolyte and zinc anode. Recently, due to the flourishing porous structure, abundant active sites, and versatile functionalization, metal–organic framework (MOF)/MOF-derived nanomaterials have been extensively investigated in AZIBs, and many significant developments have been witnessed. In this review, the components and energy storage mechanisms of AZIBs are firstly presented. Moreover, recent developments in MOF/MOF-derived nanomaterials in AZIBs are summarized in detail, and the relationship between the structure and composites of MOF/MOF-derived nanomaterials and the electrochemical performance of AZIBs is highlighted. Finally, the research directions and perspectives of MOFs/MOF-derived nanomaterials for advanced AZIBs are proposed. This review will provide instructive guidance for the rational design of MOFs or MOF-derived nanomaterials in AZIBs.
