“…The good high rate cycling performance and high coulombic efficiency could be attributed to the 3D network structure of Li 3 V 2 (PO 4 ) 3 /C, which could effectively facilitate lithium ion extraction and insertion, leading to the improvement in high rate capacity. Moreover, the long-term cycling stability at high rate of this Li 3 V 2 (PO 4 ) 3 /C compound is much better than those of previous reports using hydrothermal method [18,19,[34][35][36][37] and microwave assisted method [29,30]. For examples, Liu et al [18] reported that nanorod-like Li 3 V 2 (PO 4 ) 3 gave a discharge capacity of 101.1 mAh g -1 at 10 C (1 C = 180 mAh g -1 ) in the voltage of 3.0 -4.6 V, but there were no long tern cycling performance for Li 3 V 2 (PO 4 ) 3 (only 5 cycles).…”

“…In the literature, significant improvements have been observed when LVP bulk materials are engineered to reach the nano-level. The most commonly used methods are traditional solid-state reactions, [96][97][98] sol-gel reactions, [99][100][101] hydrothermal methods, [102][103][104] spray pyrolysis, and other methods. [105][106][107] Compared to the aforementioned methods, sol-gel and hydrothermal reactions are more favorable as they can produce LVP nanoparticles with good homogeneity, uniform morphology and controllable particle size, giving rise to a higher charge/ discharge rate.…”

Vanadium-based materials, such as V2O5, LiV3O8, VO2(B) and Li3V2(PO4)3 are compounds that share the characteristic of intercalation chemistry. Their layered or open frameworks allow facile ion movement through the interspaces, making them promising cathodes for LIB applications. To bypass bottlenecks occurring in the electrochemical performances of vanadium-based cathodes that derive from their intrinsic low electrical conductivity and ion diffusion coefficients, nano-engineering strategies have been implemented to "create" newly emerging properties that are unattainable at the bulk solid level. Integrating this concept into vanadiumbased cathodes represents a promising way to circumvent the aforementioned problems as nanostructuring offers potential improvements in electrochemical performances by providing shorter mass transport distances, higher electrode/electrolyte contact interfaces, and better accommodation of strain upon lithium uptake/ release. The significance of nanoscopic architectures has been exemplified in the literature, showing that the idea of developing vanadium-based nanostructures is an exciting prospect to be explored. In this review, we will be casting light on the recent advances in the synthesis of nanostructured vanadium-based cathodes. Furthermore, efficient strategies such as hybridization with foreign matrices and elemental doping are introduced as a possible way to boost their electrochemical performances (e.g., rate capability, cycling stability) to a higher level. Finally, some suggestions relating to the perspectives for the future developments of vanadium-based cathodes are made to provide insight into their commercialization. through the interspaces, making them promising cathodes for LIB applications.

“…Many reduction and coating agents have been used as a carbon source so far, such as, hydrogen [12], glucose [20], sucrose [21], phenolic resin [22], carbon [14], citric acid [23] and humic acid [24]. For the first time, recently we have reported the adipic acid as a carbon source and as a chelate agent in LiFePO 4 material which was prepared by simple sol-gel and solid state route [25][26][27].…”

Monoclinic Li 3 V 2 (PO 4 ) 3 powders were synthesized with different calcination temperature of 800, 900 and 950 0 C for 8 h in Ar atmosphere by solid state method using adipic acid as a chealting agent. The influence of calcination temperatures of carbon coated Li 3 V 2 (PO 4 ) 3 has been investigated using X-ray diffraction (XRD) and electrochemical methods. The crystalline phase formation was investigated using thermogravimetric-differential thermal analysis (TG-DTA). Among the optimized conditions, the sample prepared with 0.15 molar ratio of adipic acid to total metal ions at the calcination temperature of 900 0 C showed a better electrochemical performance compared to other samples. [8][9][10][11][12][13][14] have been focus of candidate as cathode materials. Among the phosphates above, monoclinic Li 3 V 2 (PO 4 ) 3 is a highly promising material proposed as a cathode for higher voltage rechargeable lithium-ion batteries because of their stable framework, good ion mobility and high reversible capacity. Li 3 V 2 (PO 4 ) 3 contains both mobile Li cations and redox-active metal sites occupied within a rigid phosphate structure. The theoretical capacity for Li 3 V 2 (PO 4 ) 3 is 197 mAh/g, while three Li ions are completely extracted at the voltage of 4.8 V, which is the highest for all phosphate [14]. In the monoclinic Li 3 V 2 (PO 4 ) 3 phase, the first charging an ordered Li phase of intermediate composition [Li 2.5 V 2 (PO 4 ) 3 ]; then the second stage (3.68 to 4.1 V) is related by the removal of Li-ions from the stable tetrahedral sites. Then, the final stage (4.1 to 4.5 V) is due to the change of the V
