Recent progress in Co–based metal–organic framework derivatives for advanced batteries

Bimetallic electronic effects of Mn-doped Ni-MOF shuttle-like nanosheets remarkably enhance the supercapacitive performance

“…8 Therefore, a possible way to obtain high specific energy of SCs without compromising specific power is to assemble well-matched HSCs comprising of one EDLC-type electrode and battery-type electrode. 9,10 Among them, the battery-type Faraday electrode significantly improves the specific energy through its inherent tremendous charge storage capacity, while the capacitive EDLC electrode is to maintain the advantages of high specific power and long cycle life. [11][12][13] It is worth noting that the hybridization of two different electrodes operating in different potential windows will expand the working voltage and thus achieve higher specific energy.…”

Ligand-Assisted Controllable Growth of Self-Supporting Ultrathin Two-Dimensional Metal–Organic Framework Nanosheet Electrodes for an Efficient Oxygen Evolution Reaction

“…Numerous studies have been reported to fully demonstrate that MOFs have become excellent precursors and templates for most metal/metal oxides/metal hydroxides/porous carbon nanocomposites, and as-prepared 2D MOF nanosheets can also be carbonized to their corresponding 3D mixed metal oxides@porous carbon arrays on various conductive substrates, which can directly serve as an ideal electrode to be applied to electrochemical testing. In particular, the MOF-derived porous carbon obtained after pyrolysis can not only promote the accessibility of catalytically active sites but also improve the electrical conductivity, resulting in a significant improvement in catalytic performance. − The samples were continuously annealed at 600 °C for 2 h (named UNi-MOFNs-2@NC, Ni-MOFNs-50@NC, and Ni-MOFNs-100@NC) with a kind of indexable metallic Ni phase of a strong and wide diffraction peak attributed to amorphous carbon. The overall morphologies of UNi-MOFNs-2@NC were characterized by SEM (Figures a and S7).…”

Recent advances in Fe-based metal–organic framework derivatives for battery applications

“…18,19 However, most MOFs exhibit poor conductivity, which limits their practical application as battery modules. 20 In order to address these shortcomings of pristine MOFs, the corresponding derivatives prepared by heat treatment of MOF precursors oen have excellent conductivity as well as many metal centers with dynamic valence, which greatly improves the performance of the material and makes Fe-MOF-derived materials as materials of great interest. 21 Fe-MOF-derived materials inherit the high surface area, uniform active heteroatom doping and stable porous structure of Fe-MOFs, showing good electrochemical performance.…”
