Enhanced Reversible Zinc Ion Intercalation in Deficient Ammonium Vanadate for High-Performance Aqueous Zinc-Ion Battery.

ABSTRACT: Ammonium vanadate with bronze structure (NH₄V₄O₁₀) is a promising cathode material for zinc-ion batteries due to its high specific capacity and low cost. However, the extraction of [Formula: see text] at a high voltage during charge/discharge processes leads to irreversible reaction and structure degradation. In this work, partial [Formula: see text] ions were pre-removed from NH₄V₄O₁₀ through heat treatment; NH₄V₄O₁₀ nanosheets were directly grown on carbon cloth through hydrothermal method. Deficient NH₄V₄O₁₀ (denoted as NVO), with enlarged interlayer spacing, facilitated fast zinc ions transport and high storage capacity and ensured the highly reversible el
