Stabilized Molybdenum Trioxide Nanowires as Novel Ultrahigh-Capacity Cathode for Rechargeable Zinc Ion Battery.

ABSTRACT: Exploration of high-performance cathode materials for rechargeable aqueous Zn ion batteries (ZIBs) is highly desirable. The potential of molybdenum trioxide (MoO₃) in other electrochemical energy storage devices has been revealed but held understudied in ZIBs. Herein, a demonstration of orthorhombic MoO₃ as an ultrahigh-capacity cathode material in ZIBs is presented. The energy storage mechanism of the MoO₃ nanowires based on Zn²⁺ intercalation/deintercalation and its electrochemical instability mechanism are particularly investigated and elucidated. The severe capacity decay of the MoO₃ nanowires during charging/discharging cycles arises from the dissolution and the structural collapse of MoO₃ in aqueous electrolyte. To thi
