Application of Conductive MOF in Zinc‐Based Batteries

Abstract

The use of conductive MOFs (c‐MOFs) in zinc‐based batteries has been a popular research direction. Zinc‐based batteries are widely used with the advantages of high specific capacity and safety and stability, but they also face many problems. c‐MOFs have excellent conductivity compared with other primitive MOFs, and therefore have better applications in zinc‐based batteries. In this paper, we discuss the transfer mechanisms of the unique charges of c‐MOFs: hop transport and band transport respectively, and further address the way of electron transport. Then, it is introduced that c‐MOFs can be prepared in various ways, among which solvothermal, interfacial synthesis and post‐processing methods are widely used. In addition, the applications of c‐MOFs are discussed in terms of their role and performance in different types of zinc‐based batteries. Finally, the current problems of c‐MOFs and the prospects for their future development are presented.This article is protected by copyright. All rights reserved

Advanced Characterization Techniques on Mechanism Understanding and Effect Evaluation in Zinc Anode Protection

“…Apart from solid electrolyte, metal-organic frameworks (MOFs) have been widely utilized in regulating interfacial ion transport for a long time. [177][178][179] But a novel mechanism to explain the MOF's role in anode protection was proposed through Raman characterization in the poles of MOF. [167] When the solvated Zn 2+ passes through the MOF, most of the solvated water molecules are excluded and only some anions enter as free or coordination anions, thus forming a supersaturated electrolyte layer.…”

Halogen-engineered metal–organic frameworks enable high-performance electrochemical glucose sensing

“…19 Metal-organic frameworks (MOFs) are an emerging class of crystalline porous coordination polymer, 20 which is constructed by organic ligands and metal ions/clusters to yield periodic two-or three-dimensional extend frameworks. 21 Their long-range ordered channels, topological diversity, and chemical tailorability have attracted considerable attention in separations, 22 catalysis, 23 batteries 24 and so forth. The previous works involving the utilization of MOFs in electrochemical glucose sensing showed the grand potential in pushing the performance.…”

Photochromic Ln-Phosphonates Assembled by an Imidazole Derivative: Construction, Crystal Structures, and Light-Enhanced Proton Conductivity

“…Coordination polymers (CPs) assembled with metal ions/clusters and organic ligands are a class of crystalline complexes and have attracted great attention in sensing detection, separation, and adsorption due to their designable and tunable structures and functional porosity. − Recently, CPs have become a new candidate material for proton conduction as the hydrogen-bond networks could be formed through introducing typical ligands with hydrophilic units or proton carriers. − In this way, high-conductivity CPs are constructed with good proton transport paths. Most importantly, the visualization of the structure of CPs provides an opportunity to explore the proton conduction mechanism and pathway, which makes it possible to analyze the structure–property relationship in depth.…”
