“…In addition, the lattice stripe spacing of Se–CoSe 2 /CNFs-12 composites is slightly increased compared with CoSe 2 standard cards, which can be attributed to the widening of the expansion of the carbon interlayer distance caused by Se-doping. 42 This also matches the XRD results depicted in Fig. 2(b).…”

With the rapid development of sodium-ion batteries (SIBs), it is urgent to exploit the cathode materials with good rate capability, attractive high energy density and considerable long cycle performance. Na3V2(PO4)3 (NVP), as a NASICON-type electrode material, is one of the cathode materials with great potential for application because of its good thermal stability and stable. However, NVP has the inherent problem of low electronic conductivity, and various strategies are proposed to improve it, moreover, nanotechnology or nanostructure are involved in these strategies, the construction of nanostructured active particles and nanocomposites with conductive carbon networks have been shown to be effective in improving the electrical conductivity of NVP. Herein, we review the research progress of NVP performance improvement strategies from the perspective of nanostructures and classifies the prepared nanomaterials according to their different nano-dimension. In addition, NVP nanocomposites are reviewed in terms of both preparation methods and promotion effects, and examples of NVP nanocomposites at different nano-dimension are given. Finally, some personal views are presented to provide reasonable guidance for the research and design of high-performance polyanionic cathode materials of SIBs.

“…Furthermore, compared to other systems that have also garnered significant research interest, such as zinc-ion batteries (ZIBs) and potassium-ion batteries (KIBs), the charge–discharge mechanisms of sodium-ion batteries (SIBs) and lithium-ion batteries (LIBs) are similar, resembling a “rocking-chair” structure. − Consequently, SIBs possess significant application prospects as a new generation of batteries. − The active materials in the anode of LIBs/SIBs can be categorized into types of intercalation, conversion, and alloying, based on their distinct electrochemical mechanisms . Primarily, intercalation-type anode materials comprise carbon materials. − Following the advancement of nanotechnology, carbon nanomaterials have been increasingly applied to the anodes of SIBs. − Carbon nanomaterials, such as carbon nanotubes and graphene, boast a large specific surface area and excellent electrical conductivity. , Although converted and alloying reaction materials exhibit significantly higher specific capacities than carbon electrodes, their volume often undergoes dramatic changes, leading to the loss of active materials and a consequent sharp decline in capacity. , Consequently, researchers often combine carbon with conversion or alloying reaction materials to synthesize nanoparticle-doped carbon nanomaterials that offer enhanced electrical conductivity and mitigate the volume changes associated with the reactions of active materials. Among these, one-dimensional nanomaterials, characterized by their large specific surface area, excellent conductivity, and short ion diffusion paths, have garnered significant attention from researchers. − Besides active materials, traditional electrodes also incorporate conductive agents, binders, and current collectors with a limited content of active materials.…”

The development of wearable devices requires flexible batteries that can be bent and folded. However, deficiencies in material flexibility, conductivity, and other aspects can affect the performance of a flexible electrode. One-dimensional nanofibers possess high specific surface area, high conductivity, and a 3D network structure that enables them to buffer stress and strain. Consequently, they hold significant potential in the field of electrochemical energy storage as flexible electrode materials. In this study, we utilized polyvinylpyrrolidone (PVP) as a template to form a supramolecular polymer (PNDS) through hydrogen bonding between 1,4,5,8-naphthalene tetracarboxylic acid (NTCA) and 3,3′-diaminobenzidine (DAB) monomers. Through core−shell electrospinning and carbonization, PNDS precursors were used to prepare polybis(benzimidazobenzophenanthroline-dione) (BBB)-based carbon nanofibers featuring a core−shell structure. The BBB polymer, featuring a continuous aromatic ring structure, undergoes conversion into a highly graphitic carbon skeleton upon carbonization at 1000 °C. This transformation enhances the conductivity of flexible electrodes, improves the current collection effect under high currents, and ensures stability in the charge−discharge cycle. The iron-containing polymers within the shell layer ultimately transform into iron oxide and iron carbide nanoparticles encapsulated within the carbon fibers, compensating for the lower specific capacity characteristic of pure carbon materials. Serving as a SIB flexible anode, the specific capacity can achieve 250 mAh g −1 after 950 cycles at 0.2 A g −1 , with negligible attenuation throughout the cycling process. This study demonstrates that BBB-based carbon nanofibers featuring core−shell structures exhibit excellent electrochemical performance while retaining flexibility, presenting clear advantages over traditional electrodes characterized by complicated processes and limited active substance content.
