Resumen

The electrochemicalperformanceof two Na2/3Ni1/3Mn2/3O2samples,preparedthroughan oleic-assistedemulsionproce-dure, is examined.The effect of cosurfactantswith either short(methylamine)or long (octylamine)chains is determinedfortheir applicabilityas cathodematerialsfor sodium-ionbatteries.Their structuraland morphologicalpropertiesare studiedby X-ray diffractionand electronmicroscopy.The electrochemicalperformanceis determinedby cyclingsodiumhalf-cellswiththe galvanostaticmethod.Particularinterestis devotedto theirkinetic propertiesevaluatedby using impedancespectroscopy
