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 -VO···H.

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...
