| 英文摘要 | Na3V2(PO4)(3) (NVP) has been in the spotlight as a potential candidate of next generation batteries to overcome the limitation of lithium resources on Earth. Here a thin-layer graphene-encapsulated NVP composite (NVP/G) was synthesized by self-assembly of surface modified NVP and graphene oxide and then followed by reduction to compensate for the intrinsic low electronic conductivity of NVP and strengthen its structure stability. The as-synthesized hybrid composite as a cathode for sodium-ion batteries (SIBs) exhibits excellent high specific capacity and superior rate performance with discharge capacities of 115.2 mA h g(-1) at 0.2 C and 70.1 mA h g(-1) at 30 C, It also shows an excellent cycling stability with about 86.0% capacity retention at 5 C after 300 cycles. Ex situ X-ray absorption spectroscopy (XAS) characterization confirmes the local geometrical environment around vanadium is highly conserved during the sodiation/desodiation process, associated with an electrochemically active V3+/V4+ redox couple. Hence the as-prepared hybrid composite can be considered as a promising cathode material for high-rate SIBs, thanks to the effect interface interaction between NVP nanoparticle sand graphene films. |
