摘要：
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 similar to 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 center dot center dot center dot H.
