| Abstract: | A rheological phase-assisted ball milling method was developed to synthesize of flower-like Li3V2(PO4)3/C composites consisting of nanofibers and nanoplate porous microstructure. The flower-like Li3V2(PO4)3/C composite delivered specific capacities of 120 and 108 mAh g?1 at 0.5 and 10 C rates, respectively. A capacity retention of 99.5 % was sustained after 100 cycles at a 10-C cycling rate. The remarkable performance was attributed to the porous nanostructures that provide short electron/ion diffusion distance and large electrode/electrolyte contact area. |
