“…More importantly, the diameter of the semicircle for the ZnO UNPs@HPCNFs at high frequency does not increase much, even after 500 cycles, thus suggesting the formation of a stable SEI layer on the surface of the electrode in the initial cycles and high structural integrity. [19] The cycling performance of MnO UNPs@HPCNFs and CoO UNPs@HPCNFs at a constant current density of 0.1 A g -1 was further evaluated (Figure 5g), the results of which clearly authenticate their superior cyclability, delivering the discharge capacity of 1118 and 1057 mAh g -1 , respectively, at the end of 100 charge-discharge cycles. By comparison, only a reversible capacity of 104 and 117 mAh g -1 after 100 cycles was observed for pure MnO and ZnO, respectively, coupled with rapid capacity fading.…”

X. (2016). General synthesis of transition metal oxide ultrafine nanoparticles embedded in hierarchically porous carbon nanofibers as advanced electrodes for lithium storage. Advanced Functional Materials, 26 (34),[6188][6189][6190][6191][6192][6193][6194][6195][6196] General synthesis of transition metal oxide ultrafine nanoparticles embedded in hierarchically porous carbon nanofibers as advanced electrodes for lithium storage AbstractA unique general, large-scale, simple, and cost-effective strategy, i.e., foaming-assisted electrospinning, for fabricating various transition metal oxides into ultrafine nanoparticles (TMOs UNPs) that are uniformly embedded in hierarchically porous carbon nanofibers (HPCNFs) has been developed. Taking advantage of the strong repulsive forces of metal azides as the pore generator during carbonization, the formation of uniform TMOs UNPs with homogeneous distribution and HPCNFs is simultaneously implemented. The combination of uniform ultrasmall TMOs UNPs with homogeneous distribution and hierarchically porous carbon nanofibers with interconnected nanostructure can effectively avoid the aggregation, dissolution, and pulverization of TMOs, promote the rapid 3D transport of both Li ions and electrons throughout the whole electrode, and enhance the electrical conductivity and structural integrity of the electrode. As a result, when evaluated as binder-free anode materials in Li-ion batteries, they displayed extraordinary electrochemical properties with outstanding reversible capacity, excellent capacity retention, high Coulombic efficiency, good rate capability, and superior cycling performance at high rates. More importantly, the present work opens up a wide horizon for the fabrication of a wide range of ultrasmall metal/metal oxides distributed in 1D porous carbon structures, leading to advanced performance and enabling their great potential for promising largescale applications.

“…The increase in capacity during cycling is commonly observed in many metal oxide-based anode materials [44, 45]. This phenomenon might be associated with the gradual activation of the Fe 2 O 3 @Co 3 O 4 composite during cycling, which enhances the accessibility of lithium ions in the electrode material [46, 47]. The FESEM and TEM images of the Fe 2 O 3 nanotubes@Co 3 O 4 electrode after cycling are shown in Fig.…”

Transition metal oxides are promising candidates for the high-capacity anode material in lithium-ion batteries. The electrochemical performance of transition metal oxides can be improved by constructing suitable composite architectures. Herein, we demonstrate a metal–organic framework (MOF)-assisted strategy for the synthesis of a hierarchical hybrid nanostructure composed of Fe2O3 nanotubes assembled in Co3O4 host. Starting from MOF composite precursors (Fe-based MOF encapsulated in a Co-based host matrix), a complex structure of Co3O4 host and engulfed Fe2O3 nanotubes was prepared by a simple annealing treatment in air. By virtue of their structural and compositional features, these hierarchical composite particles reveal enhanced lithium storage properties when employed as anodes for lithium-ion batteries.

“…During charging, the process is reversed. [7] Because of its advantages such as a high energy density, a long lifespan, little self-discharge and no memory effects, [214,224,225] the LIB is currently recognized as one of the most popular power sources for portable electronic devices and electric vehicles. [226][227][228][229][230] It is believed that the 3D CNF nanostructures not only facilitate the rapid transport of electrons along the interconnected carbon network, but also provide multidimensional buffer space for relieving the volume changes during the lithiation/ delithiation process, thereby further enhancing Li + storage capacities and improving the life span.…”

Therefore, it is necessary to develop highperformance energy storage devices for facilitating the effective utilization of intermittent renewable energy sources. [7][8][9] Among varieties of electrochemical energy storage devices, supercapacitors (known as electrochemical capacitors) [10,11] and some rechargeable batteries (lithium-ion batteries (LIBs), lithiumsulfur (Li-S) batteries, and metal-O 2 batteries) [12][13][14][15] are at the frontier, because they can transport high power and store high energy. Nowadays, they play an indispensable role in our daily life by powering numerous portable electronic devices (e.g., cell phones and laptops), hybrid electric vehicles, and large-scale electrical grids. [16][17][18][19] It is well accepted that the performance of energy storage devices mainly depended on their electrode materials. [20,21] Owing to the advantages of large surface area, light weight, good electrical conductivity, and high thermal/ chemical stability, carbon materials have been considered as the most important electrode materials of supercapacitors and rechargeable batteries [8,20,21] Hence, various nanostructured carbons, such as carbon/graphene quantum dots, [22,23] carbon nanofiber (CNFs), [16,24] carbon nanotubes (CNTs), [13,25] graphene [26][27][28][29][30][31][32] carbon nanosheets, [33,34] 3D carbon nanostructures, [35][36][37] and porous carbon, [38,39] have gained great attention. Among these materials, 3D carbon nanomaterials have some advantages. The interlinked architecture not only shortens transport distances for ions in the well-interconnected wall structure, but also provides a continuous pathway endowing for the fast electron transport. [40] Moreover, the structural interconnectivities guarantee higher electrical conductivity and better mechanical stability. [36,41] Thereby, the design and fabrication of various 3D carbonbased nanostructures, including carbon nanotube networks, graphene gels, graphene foams, and 3D CNFs, have been intensively investigated.Over the past few years, there are many reviews summarizing the progress of fabricating 3D carbon-based nanomaterials. For example, Schneider et al. overviewed the recent advance in the synthesis of 3D arranged carbon nanotube architectures. [42] Li et al. reviewed the carbon-based 3D nanostructures for supercapacitors. [36] Cao and Gui et al. comprehensively reviewed the recent progress in synthesis, properties, and energy applications of CNT sponges, aerogels, and hierarchical composites. [43] The development of high-performance electrochemical energy storage devices is critical for addressing energy crises and environmental pollution.
