· JVASP-30541· V4O9

V4O9 is a vanadium oxide ceramic compound belonging to the family of mixed-valence vanadium oxides, which exhibit interesting electrochemical and structural properties. This material is primarily investigated in research contexts for energy storage applications, particularly as a cathode material in battery systems and as a component in electrochromic devices, where its ability to undergo reversible oxidation-reduction reactions is advantageous. V4O9 is notable within the vanadium oxide family for its potential to balance electrochemical activity with structural stability, making it of interest to researchers developing next-generation batteries and smart window technologies, though industrial deployment remains limited compared to more mature oxide ceramics.
