摘要：

C@Na3V2(PO4)(2)F-3 samples were synthesized by an emulsion method using oleic acid as a surfactant and Vaseline oil as organic media of the micellar system. Their structural, chemical and morphological properties are determined by at the light of solid-state techniques, including X-ray diffraction, electron microscopy, and Raman and XPS spectroscopies. Electrochemical tests, performed by the galvanostatic method, show that the use of oleic acid as a surfactant improves the electrode kinetic properties and consequently the electrochemical behavior as a cathode for sodium-ion batteries.
