Th.ugh.th. current research.on vanadium-based glass electrodes h.s made great progress, th. conductivity th.ory of V-based glasses h.s not been obviously improved and crystals cannot be positioned precisely. Th. ch.nges in th. valence state of V3+, V4+and V5+are regulated by th. strong reducing agent Fe2P to realize valence bond transformation of th. amorph.us electrode, explore th. redox process of multi-electron reactions and furth.r optimize th. conductivity of electrode materials. VPFe2 and VPFe3 precipitate VO2crystals and VPFe4 precipitates VO2and V6O11crystals. Electron back-scattered diffraction was used to accurately identify th. distribution and specific positions of both.types of crystals. V6O11crystals exh.bit a strong texture according to pole figure and inverse pole figure. XPS reveals th.t Fe2P and V2O5, undergo a redox reaction during th. h.gh.emperature melting process, wh.re V5+is reduced to V4+and V3+and V4+renders a positive influence on conductivity. Th. addition of Fe2P increases th. content of V4+in th. glass and VPFe3 glass contains th. h.gh.st content of V4+, leading to th. h.gh.st electronic conductivity. V2O5transforms into VO2crystals and VO2transforms into V6O11with.th. increase of Fe2P content. Th. type of nanocrystal precipitation in glass affects electronic conductivity.
