Abstract
- The limited choice of anode materials always challenges the development of high performance aqueous ammonium-ion batteries (AAIBs). Herein, we fabricate amorphous molybdenum oxide (MoO<subscript>x</subscript>) materials and study the NH<subscript>4</subscript><superscript>+</superscript> storage performances. The results indicate that the optimized electrode exhibits high gravimetric/areal capacities of 175 mA h g<superscript>−1</superscript>/1.30 mA h cm<superscript>−2</superscript>, outperforming state-of-the-art anode materials for AAIBs. Our findings indicate that the valence state of Mo and the Mo–O–H content in MoO<subscript>x</subscript> synergistically control the NH<subscript>4</subscript><superscript>+</superscript> storage performances, offering new understanding for rational design of MoO<subscript>x</subscript> materials for energy storage applications.
