Energy dispersive X-ray spectroscopy (EDS) mapping showed that V-ions are not incorporated into the main structure of the nanorods but rather V behaves as a flux agent during the growth of the nanorods. The cyclic voltammetry (CV) analysis of the samples shows changes in the redox peaks as a function of V content. Our detailed ex situ X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray absorption spectroscopy (XAS) analyses after 1000 cycles show that the degradation mechanism is the formation of various titanium oxide impurity phases which inhibits the Na-ion diffusion.eninfo:eu-repo/semantics/openAccessCathode MaterialSodium StorageAnode MaterialIonLithiumNanomaterialsChallengesTitanatesArticle22142483249010.1039/c9ce01955c2-s2.0-85083079502Q2WOS:000527016600008Q1
