“…Olivine-type LiFePO 4 (LFP) and monoclinic Li 3 V 2 (PO 4 ) 3 (LVP) are the two typical representatives. Compared with LFP, LVP exhibits better ionic conductivity because it has a threedimensional path for lithium ion diffusion [12,13], while LFP only has one-dimensional curved channel [14,15]. Furthermore, the theoretical capacity of LVP calculated by three Li ions completely extracted is much higher than that of LFP.…”

“…Electrostatic spray deposition happens between nozzles and ground substrate using a high-voltage direct current (DC) voltage, which causes the precursor solution to be atomized to form an aerosol. Wang et al have synthesized LVP/C film via electrostatic spray deposition, in which the precursor solution NH 4 VO 3 , LiNO 3· H2O, H 3 PO 4 , and glucose were dissolved in a mixed solvent containing distilled water, alcohol, and 1,2-propylene glycol [85]. While applying a DC voltage of 12.5 kV between the substrate and the needle, the flow rate to feed the precursor solution was controlled at 2 ml/min by a syringe pump.…”

“…Recent results have demonstrated that carbon coating is primarily dependent on the carbon source. Therefore, various carbon sources have been employed for carbon-coated LVP, such as glucose [12,40,85,[107][108][109], sucrose [110][111][112], maltose [113], citric acid [47,[114][115][116], starch [117], carbon black [118], EDTA [119], PS spheres [71,120], β-cyclodextrin [121], carboxy methyl cellulose (CMC) [122], PEG-400 [123], and PEG-10,000 [124], etc.…”

Lithium vanadium phosphate (Li 3 V 2 (PO 4 ) 3 ) has been extensively studied because of its application as a cathode material in rechargeable lithium ion batteries due to its attractive electrochemical properties, including high specific energy, high working voltage, good cycle stability, and low price. In this review, the preparation of technology, structure, Li + insertion/extraction mechanism, and electrochemical properties of Li 3 V 2 (PO 4 ) 3 are introduced, and with particular focus on the relationship of these topics each other. The synthetic techniques of Li 3 V 2 (PO 4 ) 3 , such as high-temperature solid-state method, sol-gel method, hydrothermal method, etc. And progress of techniques in modification, such as coating and elemental doping, is reviewed. Finally, the directions for further development and prospective applications for the material are proposed.

“…However, in order to apply it in hybrid electrical vehicles (HEV), the current major issue needed to be resolved is how to improve its discharge capacity and poor cycle stability at high discharge rate. On the other hand, Li 3 V 2 (PO 4 ) 3 , which was reported almost at the same time, has a large theoretical specific capacity and excellent cycle stability, thereby drawing much attention [6,7]. In recent years, a lot of progress has been made concerning Li 3 V 2 (PO 4 ) 3 as cathode materials [8][9][10][11], in terms of its complicated internal reaction mechanism and structural transformation under different charging and discharging voltages [12]; the industrial development of Li 3 V 2 (PO 4 ) 3 has not been reported yet, just staying on the stage of experimental research.…”

Hybrid materials xLiFePO 4 ·(1−x)Li 3 V 2 (PO 4 ) 3 were synthesized by sol-gel method, with phenolic resin as carbon source and chelating agent, methylglycol as surfactant. The crystal structure, morphology and electrochemical performance of the prepared samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV), galvanostatic charge-discharge test and particle size analysis. The results show that LiFePO 4 and Li 3 V 2 (PO 4 ) 3 co-exist in hybrid materials, but react in single phase. Compared with individual LiFePO 4 and Li 3 V 2 (PO 4 ) 3 samples, hybrid materials have smaller particle size and more uniform grain distribution. This structure can facilitate Li ions extraction and insertion, which greatly improves the electrochemical properties. The sample 0.7LiFePO 4 ·0.3Li 3 V 2 (PO 4 ) 3 retains the advantages of LiFePO 4 and Li 3 V 2 (PO 4 ) 3 , obtaining an initial discharge capacity of 166 mA h/g at 0.1 C rate and 109 mA h/g at 20 C rate, with a capacity retention rate of 73.3% and an excellent cycle stability.
