Innovative 2D dioxonium vanadium oxide: enhancing stability in aqueous zinc-ion battery cathodes.

ABSTRACT: Vanadium oxide-based compounds have attracted significant interest as battery materials, especially in aqueous Zn-ion batteries, due to favorable properties and compatibility in Zn-ion systems. In a simple hydrothermal method with moderate conditions, a novel vanadium oxide compound has been synthesized using ammonium metavanadate with oxalic acid as a reducing agent. Various characterization techniques confirmed the formation of layered V₃O₈(H₃O)₂ nanoplatelets with a tetragonal crystal structure. The as-prepared cathode material was tested in coin cells against a Zn metal anode in two aqueous electrolytes of the same concentration: ZnSO₄·7H₂O and Zn(CF₃SO₃)₂. Electrochemical results showed
