Enhancement of electrical conductivity and thermal stability of Iron- or Tin- substituted vanadate glass and glass-ceramics nanocomposite to be applied as a high-performance cathode active material in sodium-ion batteries

To explore novel vanadate formulations, i.e. newly effective cathode active material for sodium-ion battery (SIB), relationships among the local structure, electrical conductivity, and cathode performance of xNa2O•10 P2O5•(85-x)V2O5•5Fe2O3 and xNa2O•10 P2O5•(85-x) V2O5•5SnO2 (5
