All-Vanadium-Flow-Energiespeicherprojekte haben Landanforderungen
XPS technique was used to elucidate the chemical composition of the samples and the tungsten oxidation state (stoichiometric vs reduced). Fig. 2 a and b demonstrates the W 4f and O 1s core-level spectra of the different tungsten oxide nanostructures. For the WpNFs prepared at pH = 2 and pH = 5, respectively, in Fig. 2 a-1 and 2a-2 four peaks are observed in
What is vanadium flow battery (VFB)?
