“…43,44 The valence of vanadium remains unchanged even with the introduction of several heteroatoms, and one pair of peaks at 523.9 eV and 516.8 eV can point to the V 3+ 2p 1/2 and V 3+ 2p 3/2 orbits reected in the spectrum. 42,45,46 Furthermore, the spectrum of the phosphorous element can be tted into two peaks at 134.7 eV and 133.4 eV, and this result agrees well with other related research. 47 For a specic survey of morphology regulation by the multiple ions, the exact pore distribution and the Brunauer-Emmett-Teller (BET) surface area test of KLS were studied by nitrogen de/absorption.…”

“…The shallower the extraction/insertion degree of sodium ions, the less damage to the material structure. Similar results are often reported by other researchers. ,, From the above discussion, anyone can safely conclude that NVPF@C-T prepared by introducing TA in two steps has a higher capacity and better cycle performance than NVPF@C-O prepared by introducing TA in one step. Moreover, compared with other works, ,− NVPF@C-T still delivers a relatively larger capacity and higher capacity retention (Table ).…”

Carbon-coated Na3V2(PO4)2F3 (NVPF@C) composites are prepared using tannic acid as a chelating agent and carbon source via a sol–gel process-assisted solid-state reaction for the first time. When introducing tannic acid in two steps, a complete and uniform carbon coating layer can be successfully fabricated because the tannic acid added in the second step can repair the discontinuous and uneven coating obtained by the first coating. This uniform carbon layer can not only effectively improve the electronic conductivity of NVPF and accelerate Na+-ion diffusion but also prevent NVPF from being corroded by the electrolyte. As a result, the carbon-coated NVPF composite prepared by introducing tannic acid in two steps has a higher initial capacity (124.5 mAh g–1 at 0.2 C) and a better cycle stability (94.8% capacity retention ratio over 300 cycles at 10 C) compared to pristine NVPF and another carbon-coated NVPF composite prepared by introducing tannic acid in one step. Therefore, this work not only finds a cheap chelating agent for the sol–gel process but also develops an effective strategy for coating materials with poor electronic conductivity.

“…The size, morphology and structure of the nanomaterials can then be regulated by controlling the composition and structure of the microreactor [66][67][68]. Salehi et al have synthesized NVP nanoparticles by using CTAB as a template at the appropriate concentration [69]. In the solution where the appropriate concentration is probed, spherical micelles with positively charged surfaces are formed.…”

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.
