“…: 80-1515). The results are similar with that of previous literatures [6][7][8]10,14]. Moreover, no diffraction peak related to B-GS can be detected based on the XRD analysis, which may be due to the low content of the added B-GS.…”

“…Unfortunately, the major challenge for Li 3 V 2 (PO 4 ) 3 cathode is the poor cycling stability due to the low electronic conductivity (2.0 x 10 -8 S cm -1 ) [5]. Over the past decade, several approaches have been adopted to overcome this obstacle such as scaling down the particle size, doping with metal ions or coating with conducting materials [6][7][8].…”

The boron-doped graphene decorated Li 3 V 2 (PO 4) 3 composite (Li 3 V 2 (PO 4) 3 /B-GS) has been successfully synthesized for the first time using a facile method. The effects of B-GS on the structure, morphology and electrochemical performance of Li 3 V 2 (PO 4) 3 cathode are investigated. The results show that the nano-sized Li 3 V 2 (PO 4) 3 particles are about 80 nm on an average and are uniformly dispersed on the conducting B-GS. This combined favorable

“…Even though, there is a small difference between the both values after all. The reason for this is that photoelectron signals of XPS are hindered by the existence of carbon and CeO 2 on the surface of LVP [34]. Initial charge/discharge profiles are shown in Fig.…”

“…Analogous to other cathode materials, metallic oxides coatings are chosen to overcome this instability. For example, RuO 2 [203], SiO 2 [201,239], MgO [202], ZrO 2 [240], Al 2 O 3 [241], CeO 2 [242] and MnO [243] are used to modify the surface of LVP. Besides, the sample b also has twice the ionic conductivity of LVP/C.…”

Lithium ion batteries are essential energy storage devices that power the electronics that let us share information and connect with people anywhere at any time. As the demand for uninterrupted energy performance rises, corresponding challenges need to be overcome in both industry and academia. Currently, cathode performance limits energy-power density in Li-ion batteries. Materials chemists and scientists have devoted much effort to explore cathodes with higher capacities and electrochemical potentials. Lithium vanadium phosphate, a rising star in the cathode family, has attracted more attention in recent years because it can display a high average potential (>4.0 V) and specific capacity (197 mAh/g) with excellent structural stability during cycling. However, the separated VO 6 octahedra intrinsically limit electrical conductivity, which hurts the rate capability. This review focuses on the fundamental issues in lithium vanadium phosphate and summarizes its crystal structure, ion diffusion, and electrochemical characteristics. Three synthetic aspects are described carefully: doping, composite and designing microstructures. At the same time, some rules are distilled from the report results, which may be referred to in order to tune the electrochemical performance in electrode materials.
