ABSTRACT
Rechargeable batteries employing ammonium (NH4+) ions have attracted widespread interest owing to the abundant resources, eco-friendliness, and sustainability of NH4+ ions. Herein, an organic-inorganic hybrid is applied to organic NH4+ ion batteries. A poly (3,4-ethylene dioxythiophene) (PEDOT)-intercalated vanadium oxide nanowire (noted as VO-P-x) is applied for organic NH4+ ion storage. VO-P-x with the optimal content of PEDOT showed an interlayer spacing (d-spacing) expanded to 1.82 nm, exhibiting an ultrahigh initial coulombic efficiency of 91% and a reversible capacity of 163 mA h g-1. A significant improvement in NH4+ ion storage was achieved due to the large interlayer spacing and conductive polymer PEDOT. Combining ex situ X-ray photoelectron spectroscopy (XPS) and multi-sweep cyclic voltammetry tests, the NH4+ ion storage mechanism of VO-P-x was clearly revealed. This study provides a new strategy for designing high-performance organic ammonium batteries.
