“…It is generally accepted that lithium ions can be accommodated in the aromatic ring of organic materials theoretically. [13][14][15] Each C 6 aromatic ring can accept as many as 6l ithium ions to form a1 :1 Li/C complex.

Recently, carboxylate metal‐organic framework (MOF) materials were reported to perform well as anode materials for lithium‐ion batteries (LIBs); however, the presumed lithium storage mechanism of MOFs is controversial. To gain insight into the mechanism of MOFs as anode materials for LIBs, a self‐supported Cu‐TCNQ (TCNQ: 7,7,8,8‐tetracyanoquinodimethane) film was fabricated via an in situ redox routine, and directly used as electrode for LIBs. The first discharge and charge specific capacities of the self‐supported Cu‐TCNQ electrode are 373.4 and 219.4 mAh g−1, respectively. After 500 cycles, the reversible specific capacity of Cu‐TCNQ reaches 280.9 mAh g−1 at a current density of 100 mA g−1. Mutually validated data reveal that the high capacity is ascribed to the multiple‐electron redox conversion of both metal ions and ligands, as well as the reversible insertion and desertion of Li+ ions into the benzene rings of ligands. This work raises the expectation for MOFs as electrode materials of LIBs by utilizing multiple active sites and provides new clues for designing improved electrode materials for LIBs.

“…The mixed valence dimer related to the Fe(III)/Fe(II) (Figure b) localized states produced fractional crystallographic sites for the insertion of lithium, leading to the stabilization of a delocalized electronic state for metallic molecular orbitals. Shen et al revealed that both the Fe cluster and organic ligand (O‐Li + interaction) could conduce to the lithiation/delithiation behaviors . The Li‐induced insertion mechanism could deliver powerful tools to design new Fe‐MOFs‐based electrodes and envisage ligand functionalization for the improvement of electrochemical efficiency.…”

Among uncountable MOF materials, iron-containing metal organic frameworks (Fe-MOFs) have excellent potential in practical applications owing to their many fascinating properties, such as diverse structure types, low toxicity, preferable stability, and tailored functionality. Here, recent research progresses of Fe-MOFs in attractive features, synthesis, and multifunctional applications are described. Fe-MOFs with porosity and tailored functionality are discussed according to the design of building blocks. Four types of synthetic methods including solvothermal, hydrothermal, microwave, and dry gel conversion synthesis are illustrated. Finally, the applications of Fe-MOFs in Li-ion batteries, sensors, gas storage, separation in gas and liquid phases, and catalysis are elucidated, focusing on the mechanism. The aim is to provide prospects for extending Fe-MOFs in more practical applications.Iron-Based Metal Organic Frameworks www.advancedsciencenews.com

“…Since MOF has a large accessible surface area and porosity, which is much larger than the porosity of porous materials such as zeolite, it is particularly useful for rapid mass transfer of related substances in electrochemical applications.

In recent years, lithium‐ion batteries (LIBs) have been widely used in many fields, and research on LIBs electrode materials have attracted much attention. Among them, transition metal selenides (TMSs) are the most promising candidates in the next generation LIBs due to their high theoretical specific capacity and electrical conductivity. However, poor cycle stability and severe volume variation result in serious capacity decay during the charge/discharge process, limiting the practical application. In this paper, CoSe2−MnSe2 composites are synthesized via Co−Mn‐based metal‐organic framework (MOF) precursor. Meanwhile, three types of materials are successfully synthesized including CoSe2‐MnSe2@reduced graphene oxide (rGO), CoSe2‐MnSe2@polypyrrole (PPy), and CoSe2‐MnSe2/glucose (C). According to the electrochemical test results, it can be seen that the electrochemical performance of CoSe2−MnSe2 has been improved significantly. CoSe2‐MnSe2@rGO electrode materials, in particular, of which the inactivation defect sites and special carbon structure of rGO could provide more attachment points for ions. Due to the perfect combination of rGO and CoSe2−MnSe2, the CoSe2‐MnSe2@rGO composites display outstanding rate performance (1266 mA h g−1 at current densities of 100 mA g−1) and high reversible capacity (1169 after 150 cycles at 100 mA g−1). We believe that CoSe2‐MnSe2@rGO is a kind of very promising anode material.
