Abstract

Abstract : We fabricated a series of amorphous molybdenum oxide materials for aqueous NH4 + storage. The valence state of Mo and the content of Mo–OH component in MoO x synergistically control the NH4 + storage performance of Mo-based materials. 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 x ) materials and study the NH4 + storage performances. The results indicate that the optimized electrode exhibits high gravimetric/areal capacities of 175 mA h g −1 /1.30 mA h cm −2, 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 x synergistically control the NH4 + storage performances, offering new understanding for rational design of MoO x materials for energy storage applications.
