“…Figures 1I,J show the morphology of ZnO@C ZIF-8 . After pyrolysis treatment, the spherical structure was preserved, and the surface became rougher, which is ascribed to the decomposition of the organic-functional groups in ZIF-8 ( Li et al, 2020 ). The average size of ZnO@C ZIF-8 is about 600 nm.…”

“…The result indicates that the samples mainly comprise a mesoporous structure (2–50 nm). The formation of mesoporous structure for ZnO@C ZIF-8 is ascribed to the release of gas-phase compounds in the ZIF-8 during the carbonization ( Li et al, 2020 ). The structural characteristics of mesoporous are helpful for the transportation of Li + ions and the improvement of the active site.…”

“…Zeolitic-imidazolate frameworks (ZIFs) are novel 3D framework materials that have received wide attention due to their well-designed morphology, ordered pore structure, and high stability ( Lin et al, 2020 ; Huo et al, 2021 ; Xu et al, 2022 ). The pyrolysis product of ZIFs is a porous carbon material with a considerable specific area and conductivity under anaerobic conditions ( Jiang et al, 2017 ; Li et al, 2020 ). Based on the aforementioned summary, we successfully synthesized a unique hierarchical ZnO nanosphere coated with ZIF-8 inherently derived porous carbon shell (ZnO@C ZIF-8 ) by using a simple hydrothermal method following pyrolysis.…”

Nickel–zinc (Ni-Zn) secondary battery that is environmentally friendly and inexpensive has been regarded as a promising rechargeable battery system. However, the generation of deformation and dendrites of the traditional zinc anode during the cycling can cause capacity degradation and impede its practical application. Herein, we design a hierarchical ZnO nanosphere coated with an inherently derived ZIF-8 porous carbon shell (ZnO@CZIF-8) using a simple controllable method. The conductive carbon shell and porous ZnO core can provide more active sites, allow the fast transfer of electrons, and buffer the volume expansion of the electrode effectively. Benefiting from the synergistic effect amid the inherently ZIF-8–derived carbon shell and ZnO core, ZnO@CZIF-8 nanospheres exhibit a satisfying capacity of 316 mAh g−1 at a current density of 1 A g−1 after 50 cycles and an outstanding rate capacity when acting as the anode for a Ni-Zn secondary battery with merchant agglomerative Ni(OH)2 as the cathode. These results imply that the ZnO@CZIF-8 nanosphere is a hopeful anode for a high-energy Ni-Zn secondary battery.

“…This is mainly because CNFs can not only improve the conductivity of the electrodes, but its internal pores can also facilitate the reversible embed/de-embed of Li + ions. In addition, FeS 2 nanoparticles can be uniformly distributed in the pores, increasing the contact area between the FeS 2 and Li + ions, and effectively prevent the dissolution of polysulfides generated during the discharge process (Li et al, 2020). 2FeS 2 @CNFs also have many pores, but the content of FeS 2 is relatively low, so the specific capacity is less than that of 3FeS 2 @CNFs.…”

Pyrite (FeS2) is one of the potential candidates for advanced rechargeable Li-ion batteries (LIBs) owing to its inherent capacity (849 mAh g−1), environmental friendliness, and abundant natural resources. However, the volume expansion of FeS2 and the dissolution of polysulfide in the electrochemical reaction severely limit its application in the field of energy conversion and storage. Herein, FeS2 nanoparticles are encapsulated in S/N co-doped three-dimensional multi-channel structural carbon nanofibers (FeS2@CNFs) through the electrospinning method. As a cathode material for LIBs, FeS2@CNFs demonstrated excellent rate property and cyclic stability. The 3FeS2@CNFs (weight ratio of FeS2 is 30%) present the initial capacity of 1,336.7 mAh g−1 and the remaining 856.5 mAh g−1 at 0.02A g−1 after 100 circles. The favorable electrochemical properties have confirmed that carbon nanofibers can enhance the electroconductivity of electrodes, reduce the volume collapse of FeS2, and remit the dissolution of polysulfide during the Li+ ions insertion/de-insertion process. In addition, co-doped S/N can supply abundant active sites for electrochemical reactions, providing enough space for Li+ ion storage. The results indicate that 3FeS2@CNFs is a cathode with a developmental prospect for LIBs.

“…The resulting composites have the same hollow, ball-in-ball structure as their MOF precursor 140 ZnO@PAN composite nanofibers retained reversible specific capacities of 506.6 and 455.4 mAhg À1 at 1000 mAg À1 after 500 cycles, respectively. 144 Transition metal phosphides are also considered as remarkable anode material for high energy LIBs. 145 Nonetheless, lowering of capacity during the charging/ discharging cycles due to the mechanical pulverization is limiting their further progress in the area of LIBs applications.…”

Summary Lithium‐ion batteries (LIBs) have drawn extensive research interests due to their noticeably enhanced gravimetric energy density relative to other chemical batteries. The potential utility of metal‐organic frameworks (MOFs) and their derivatives has recently been recognized as highly effective anode components for LIBs because they can be tuned to select specific metal sites and/or to adjust pore sizes. In this work, their electrochemical performance as anodic materials is carefully evaluated with respect to lithium‐ions storage capacity, energy/power, stability, and flexibility. Furthermore, through the coordination of the organic linker and metal center, MOFs can benefit from enhanced catalytic activities in the design of advanced LIBs. For future research for next‐generation LIBs, scientific focus should be placed on the development of diverse features of MOF‐based composites such as core‐shell MOFs, mono/bi‐metal doped MOFs, dual organic linker‐based MOFs, MOFs@MOFs core shell structure, and dual organic ligands‐based MOF. As such, MOF‐based LIB electrode materials are expected to expand their utility with the improvement in topology and functionality in association with the dimensionality, pore size, and surface area.
