Abstract

Abstract : Layered polyaniline intercalated V2 O5 with an expanded layer of ∼1.55 nm exhibits an extremely high ammonium storage capacity. Abstract : A 1.55 nm-interlayer spacing-expanded polyaniline-intercalated vanadium oxide, as a new electrode material for NH4 + -ion batteries, exhibits the highest ever reported capacity of ∼307 mA h g −1 at a current density of 0.5 A g −1 . In situ FT-IR and XPS studies confirm the reversible NH4 + storage is accompanied by H bond formation/breaking within the functional group of –VO···H.
