The Synthesis of Manganese Hydroxide Nanowire Arrays for a High-Performance Zinc-Ion Battery.

ABSTRACT: The morphology, microstructure as well as the orientation of cathodic materials are the key issues when preparing high-performance aqueous zinc-ion batteries (ZIBs). In this paper, binder-free electrode Mn(OH)₂ nanowire arrays were facilely synthesized via electrodeposition. The nanowires were aligned vertically on a carbon cloth. The as-prepared Mn(OH)₂ nanowire arrays were used as cathode to fabricate rechargeable ZIBs. The vertically aligned configuration is beneficial to electron transport and the free space between the nanowires can provide more ion-diffusion pathways. As a result, Mn(OH)₂ nanowire arrays yield a high specific capacitance of 146.3 Ma h g^-1 at a current density of 0.5 A g^-1. They also demonstrates ultra-high diffus
