As the energy crisis turning out to be more and more serious, an interest in renewable energy sources is also increasing. [3] Researchers around the world have been devoting themselves to developing a high-performance electric energy storage material [4] to meet the demand for ecofriendly, sustainable, and low-cost energy. Among several kinds of electrical energy storage systems, lithiumion batteries have been developed as largescale energy storage units [5] and energy storage medium in electric vehicles, [6] smart grids, and other clean energy systems such as solar and wind since 1990s. [7] The lithium ion battery is identified as one of the ideal candidates to meet these requirements due to its desired energy density, superior voltage, and light weight. [8] However, extensive application of lithium ion batteries faces challenges related to the availability and cost of lithium. Scientists have their eyes on making sodium ion batteries as an alternative, because sodium is more abundant than lithium. Except that, it is also cheaper and easy to recover. [9] So nowadays, studying new kinds of electrode materials for lithium ion batteries and sodium ion batteries can be a rewarding work.During the last few decades, LiFePO 4 has attracted much attention, which was reported as a positive electrode for rechargeable lithium ion batteries first by Good-enough and co-workers in 1990s. [10] Nowadays, thousands of research publications have been authored on LiFePO 4 , [11] such as graphene-encapsulated LiFePO 4 composite, [12] pure LiFePO 4 , and LiFePO 4 /C, [13] 3D porous LiFePO 4 , [14] olivine LiFePO 4 , [15] mesoporous carboncoated LiFePO 4 , [16] graphene-modified LiFePO 4 , [17] LiFePO 4 / reduced graphene oxide hybrid, [18] and so on. LiFePO 4 owns favorable kinetics of the lithium intercalation/deintercalation process [19,20] and its nanocrystal size and shape can be easily controlled, [21] especially when it is complexed with carbon-based materials or other elements, the electrochemical properties of the composite material can be greatly improved. [22,23] It also has advantages of atop safety, environmental friendliness, affordability, as well as its comparatively reasonable electrochemical performance. [24][25][26][27] Until now, many researchers have examined LiFePO 4 as next generation cathode material. [28] Since FePO 4 also shows intrinsically poor ionic and electrical conductivity, small tap density which influences its electrochemical performance, [29] LiFePO 4 will not be further discussed in this article.High-performance electric energy storage material has recently developed due to the attention for sustainable development. As ecofriendly energy storage device, lithium ion batteries and sodium ion batteries deserve more concern today. FePO 4 and NaFePO 4 share similar advantages such as easy preparation, abundant, and inexpensive, so they can be ideal materials for lithium/sodium ion batteries. This review is focused on recent progresses in nanostructured FePO 4 /NaFePO 4 -based nanomaterial as cathode ma...

“…have observed that, under N 2 atmosphere, the chain‐stripping elimination of H 2 O is completed at 350°C while PVA is converted into an un‐saturated aliphatic polymer, which is further decomposed into a char at 700–800°C with about 4% carbon residue . Such a considerable carbon residual behavior have attracted much attention from various research fields, especially for some battery electrode materials with a low electronic conductivity, such as LiFePO 4 and Li 3 V 2 (PO 4 ) 3 because it can form a carbon coating on the particles of these phosphate materials and significantly improve their electrochemical performances. Besides, the formation of un‐saturated polymer intermediate product upon the elimination of H 2 O from PVA is favorable to produce more graphitic carbon due to the presence of conjugating ‐C=C‐C=C‐ carbon chains.…”

Four different high‐valent transition metal oxides (VO2, Nb2O5, Ta2O5 and WO3) are investigated for the catalytic effect on the carbonization of polyvinyl alcohol. X‐ray diffraction, infrared carbon‐sulfur analyzer, transmission electron microscopy and Raman spectroscopy are employed to study the compositions and structures of the residual carbon and resulted metal oxides. The roles of different high‐valent transition metal oxides and specific surface areas are discussed in the high temperature carbon thermal reduction process for the residue and form of carbon. It is found that VO2 as the most effective catalyst and polyvinyl alcohol as the carbon source leads to the highest amount of carbon residue (21.34 wt%) and the lowest ratio of sp3 to sp2 (0.18).

“…It is acknowledged that the cathode materials play a key role in high-performance SIBs. Hence, the reports on cathode materials, such as Na x MnO 2 [10], NaFeF 3 [11], NaCrO 2 [12], NaMPO 4 [13,14], Na 0.67 Mn 0.65 Fe 0.2 Ni 0.15 O 2 [15], V 2 O 5 [16], used for sodium ion batteries is continuously growing. Among these, Na 3 V 2 (PO 4 ) 3 (NVP), a NASICON-structure with open three dimensional framework, has an excellent ionic conductivity and good thermal stability, allowing it to be used as a suitable cathode material for sodium ion battery systems [17].…”

This work focuses on the preparation of a 3D flexible Na 3 V 2 (PO 4 ) 3 /C fiber membrane, as selfstanding cathode for Na-ion batteries, via a facile and simple electrospinning method, is followed by a hot-pressing process. A series of heat treatment temperatures are studied in detail, it is found that the temperature of the thermal process is a key parameter for controlling the structural organization of the material, as well as the size and dispersion of Na 3 V 2 (PO 4 ) 3 nanoparticles on the carbon surface. Hence, Na 3 V 2 (PO 4 ) 3 nanoparticles, with a size of 40 nm and highly disperse on the carbon nanofibers, are obtained after calcination at 800°C. In addition, this sample (Na 3 V 2 (PO 4 ) 3 /C Nanofiber-800) exhibits the best electrochemical performances among all the samples. For instance, it displays a considerably high initial discharge capacity of 109, 84, 77, and 71 mA h g −1 at a current density of 0.1, 10, 20, and 30 C, respectively. Moreover, the Na 3 V 2 (PO 4 ) 3 /C Nanofiber-800 shows notable cycle stability with about 95.3% capacity retention of its initial capacity after 1000 cycles at 2 C, These high performances is attributed to the unique nanofiber structure and uniform distribution of Na 3 V 2 (PO 4 ) 3 nanoparticles in the highly conductive carbon matrix.
