Necklace-like NiCo<sub>2</sub>O<sub>4</sub>@carbon composite nanofibers derived from metal–organic framework compounds for high-rate lithium storage

Electrospinning has rapidly progressed over the past few decades as an easy and versatile way to fabricate fibers with diameters ranging from micrometers to tens of nanometers that present unique and intricate morphologies. This has led to the conception of new technologies and diverse methods that exploit the basic electrohydrodynamic phenomena of the electrospinning process, which has in turn led to the invention of novel apparatuses that have reshaped the field. Research on revamping conventional electrospinning has principally focused on achieving three key objectives: upscaling the process while retaining consistent morphological traits, developing 3D nanofibrous macrostructures, and formulating novel fiber configurations. This review introduces an extensive group of diverse electrospinning techniques and presents a comperative study based on the apparatus type and output. Then, each process's advantages and limitations are critically assessed to identify the bona fide practicability and relevance of each technological breakthrough. Finally, the outlook on future developments of advanced electrospinning technologies is outlined, with an emphasis on upscaling, translational research, sustainable manufacturing and prospective solutions to current shortcomings.

or loop shapes. The particles (i.e., building blocks) could be spherical spheres, cubes, rods, disks, bipyramids, etc. Another type of NNs are formed when the particles are connected by linkers or threaded onto a string or stem (type II). The strings or stems could be polymer chains, nanowires, nanorods, nanotubes, nanobelts, etc. The third type of NNs is comprised of particles that are deposited on a robust support to form a periodic arrangement that resembles a necklace (type III). The supports could be polymers, nanorods, nanotubes, nanofibers, etc.Although these three types of necklacelike nanostructures are quite different from each other in shape and morphology, they all possess some common features, such as intrinsic high surface area, abundant transport channels, exposure of each component to the surface, and multiscale roughness of the surface (as compared to other 1D nanogeometries such as rods, wires, fibers, tubes, and belts). Most type I necklace-like nanostructures are discontinuous structures that consist of 1D aligned building blocks. The interparticle distance between the building blocks is crucial to the properties of the necklace-like nanostructures. When the interparticle distance is sufficiently short, coherent optical properties are obtained through near-field coupling of their surface plasmon resonances. [11] Additionally, electromagnetic coupling between isolated nanoparticles (NPs) is much lower than the electromagnetic interactions between NPs in close proximity in a necklace-like nanostructure. [12] The static electromagnetic interactions between neighboring metallic NPs in necklacelike nanostructures may contribute to an enhancement of nonlinear optical properties and surface-enhanced Raman scattering (SERS) effect. For type II necklace-like nanostructures, the bead-on-string architecture may provide facile electron transfer and percolation, an open scaffold for ion accessibility, maximized surface area to volume ratio, and good strain tolerance, all of which are highly conducive to energy storage. [13] For type III necklace-like nanostructures, the percolating clusters of metallic or semiconductor NPs show different electrical properties because of their interparticle electron transport. [14] Thus, decorating metallic or semiconductor NPs over a robust support to form necklace-like structures is a promising strategy to craft single-electron devices. [15] Notably, NNs possess a unique surface morphology that is distinctly different from the smooth surface of nanorods, nanotubes, and nanowires. Necklace-like structures possess multiscale roughness, which renders themThe shape-controlled synthesis of nanocrystals remains a hot research topic in nanotechnology. Particularly, the fabrication of 1D structures such as wires, rods, belts, and tubes has been an interesting and important subject within nanoscience in the last few decades. 1D necklace-like micro/nanostructures are a sophisticated geometry that has attracted increasing attention due to their anisotropic and periodic structure, in...

“…Among them, the performance of NiÀ Co TMOs is particularly outstanding, compared with pure Co or Ni TMOs. The two redox pairs Ni 2 + /Ni 3 + and Co 2 + /Co 3 + found in NiÀ Co TMOs provide active centers for generating pseudo-capacitance and stronger electrochemical activity [5,6]. However, during the process of battery charging and discharging, the material volume expansion inevitably causes serious deformation of its microstructure, which seriously affects its electrochemical performances and may cause irreversible damage to the battery [7].…”

Due to excellent electrochemical performances, mixed transition metal oxides (TMOs) as electrode materials have attracted scholarly attention. However, the issues of volume expansion, unstable structure, and low electrical conductivity have limited their development for lithium battery (LIB). Drawing on the strategy of MOFs derivation synthesis combined with low temperature hydrothermal method, this study successfully synthesized the three‐dimensional (3D) NiCo2O4@Fe2O3 with a flower‐like crossing channel and a surface crumpled structure. As anode for LIBs, NiCo2O4@Fe2O3 exhibits more reliable performance than Ni−Co oxides. Our experiments verified that the Ni−Co composite electrical conductivity and cycling stability were both improved by the Fe2O3 coating. Under the high current density of 1000 mA g−1, the capacity decay rate of NiCo2O4@Fe2O3 tends to be stable after 60 cycles, and the capacity remains at 945 mAh g−1 after 400 cycles. Besides, the specific crossing porous‐channel structure mode improved the composite's carrier transport efficiency, and coulombic efficiency reached 100 % after 400 cycles. Noteworthy is the fact that the crumpled surface structure formed by the 2D Ni−Co nanosheets promotes the construction of heterostructures, further enhances the interface capacitance effect, and strengthens the rating capacity.
