摘要：

A Na3V2(PO4)(3)/C cathode synthesized by a polyol-assisted pyro-synthetic reaction and subsequent sintering delivered a discharge capacity of 235 mA h g(-1), corresponding to an extraction of 4 Na per formula with steady capacity retention and impressive rate capabilities that maintain 56% of theoretical capacity at 2.67 C.
