Highlights A vanadium oxide (TMPA-VOH) is synthesized with trimethylphenylammonium cations chemically pre-inserted into hydrated vanadium oxide. The pre-intercalation of weakly polarized organic cations strategically utilizes both ionic and molecular pre-intercalation effects. TMPA-VOH, with modified crystal structure and morphology, increased V4+ content, and weakened electrostatic interactions between Zn2+ and the V-O lattice, demonstrates enhanced voltage, storage capacity, structural stability, and reaction kinetics.
