“…(3) Conductivity. The majority of MOF-based materials deliver poor electric conductivity because of insulating organic ligands and the limited overlap between the p orbitals of organic linkers and the d orbitals of the metal ions [ 85 , 86 ]. In combination with other conductive materials such as rGO, it will make their widespread use cost prohibitive.…”

Aqueous zinc-ion batteries (AZIBs) are promising for large-scale energy storage systems due to their high safety, large capacity, cost-effectiveness, and environmental friendliness. However, their commercialization is currently hindered by several challenging issues, including cathode degradation and zinc dendrite growth. Recently, metal-organic frameworks (MOFs) and their derivatives have gained significant attention and are widely used in AZIBs due to their highly porous structures, large specific surface area, and ability to design frameworks for Zn2+ shuttle. Based on preceding contributions, this review aims to generalize two design principles for MOF-based materials in AZIBs: cathode preparation and anode protection. For cathode preparation, we mainly introduce novel MOF-based electrode materials such as pure MOFs, porous carbon materials, metal oxides, and their compounds, focusing on the analysis of the specific capacity of AZIBs. For anode protection, we systematically analyze MOF-based materials used as 3D Zn architecture, solid electrolyte interfaces, novel separators, and solid-state electrolytes, highlighting the improvement in the cyclic stability of Zn anodes. Finally, we propose the future development of MOF-based materials in AZIBs. Our work can give some clues for raising the practical application level of aqueous ZIBs.

“…As an alternative to synthetic templates, MOF-derived porous materials as ideal electrodes for ZIB, exhibiting the advantages of controllable porous structures without the need for additional templates or cumbersome procedures, have been investigated in recent years. This is owing to their persistent inherent porosity and metal species [43,46]. As organic-inorganic hybrid materials with intramolecular pores, MOFs consist of the self-assembly of organic ligands and coordination bonds of metal ions or clusters [47].…”

Porous materials as electrode materials have demonstrated numerous benefits for high-performance Zn-ion batteries in recent years. In brief, porous materials as positive electrodes provide distinctive features such as faster electron transport, shorter ion diffusion distance, and richer electroactive reaction sites, which improve the kinetics of positive electrode reactions and achieve higher rate capacity. On the other hand, the porous structures as negative electrodes also exhibit electrochemical properties possessing higher surface area and reducing local current density, which favors the uniform Zn deposition and restrains the dendrite formation. In view of their advantages, porous electrode materials for ZIB are expected to be extensively applied in electric and hybrid electric vehicles and portable electronic devices. In this review, we highlight the methods of synthesizing porous electrode materials and discuss the mechanism of action of porous structures as electrodes on their electrochemical properties. At the end of this review, the perspectives on the future development of porous materials in the field of electrochemical energy storage are also discussed.

“…However, the low capacity (≤320 mA h g –1 ) and poor cycle life (≤1000 cycles) inhibited its development in AZIBs . Therefore, it is necessary to look for electrodes with high capacity and long lifespan from the perspective of metal and organic ligands. , In addition, the mechanism of MOF-based electrodes for AZIBs is ambiguous because of complex reaction and processes, the need for in-depth characterization and analysis mechanism is very urgent. − …”

Widespread interest has been generated by aqueous zinc batteries (AZIBs), which have excellent theoretical capacities (820 mA h g–1), a low redox potential (−0.76 V vs SHE of Zn metal), and high security. Suitable cathodes for constructing high performance AZIBs are of great signification. Metal–organic frameworks (MOFs) with adjustable structure via metals and organic units show great potential in AZIBs. In this work, ZnMn-Squaric acid (ZnMn-SQ) was synthesized using squaric acid through coprecipitation and served as the cathode for AZIBs. The ZnMn-SQ electrode demonstrated a high capacity of 489.1 mA h g–1 at 0.2 A g–1. Meanwhile, ZnMn-SQ can obtain 80.7 mA h g–1 after 1300 cycles, showing an outstanding long cycle life. More importantly, ex situ characterizations of XRD, XPS, and FT-IR revealed that ZnMn-SQ undergoes a structural transformation from the initial ZnMn-SQ framework to manganese oxide accompanied by Zn-SQ and then reduced to MnOOH, ZnMn2O4, and Zn4SO4(OH)6·5H2O (ZHS) in subsequent cycles. In addition, a modified zinc anode using cubic porous Zn-SQ-3d was used to construct ZnMn-SQ // Zn-SQ-3d@Zn(Zn-SQ-3d-coated Zn) high performance AZIBs, the capacity of which reaches 171.3 mA h g–1 at 1 A g–1 after 660 cycles. This work provided chances for constructing high-performance zinc ion batteries using MOF compounds.
