Synthesis of carbon coated Li3V2(PO4)3/reduced graphene oxide composite for high-performance lithium ion batteries

Li3V2(PO4)3/graphene nanocomposite as a high performance cathode material for lithium ion battery

“…The diffraction peaks of both samples reveal a single-phase corresponding to the monoclinic structure of LVP and are well indexed to the space group of P2 1 /n, thereby indicating that crystalline LVP can be obtained through the solvothermal method. All peaks in the XRD patterns are also in good agreement with those reported in the literatures [39,40]. Graphene peak is not detected on the XRD pattern of the LVP/graphene nanocomposite sample, which indicates that the graphene nanosheets were randomly distributed between the LVP nanoparticles.…”

In-situ synthesis of reduced graphene oxide modified lithium vanadium phosphate for high-rate lithium-ion batteries via microwave irradiation

“…For the pristine Li 3 V 2 (PO 4 ) 3 , the discharge specific capacity fades down to 135.7 mAh g -1 after 100 cycles with capacity retention of 87.5%. On the contrary, the Li 3 V 2 (PO 4 ) 3 /RGO composite shows higher discharge capacity and better cyclic ability due to the added conductive RGO nanosheets, which is consistent with the related reports [40,44].…”

“…1. As far as we know, such an excellent cycling performance for Li 3 V 2 (PO 4 ) 3 /RGO is seldom in the previously reported results[40,44,45].…”

The high electrochemical performance of Li 3 V 2 (PO 4 ) 3 supported by graphene and carbon-nanofibers for advanced Li-ion batteries

“…Graphene has positive properties in energy storage devices, especially in high surface area and electronic conductivity [27][28][29][30][31][32]. However, their closed-stacking structure can prevent electron transport in the vertical direction and limit the high electrochemical performance.…”
