Our results provide an efficient and practical approach to enhance commercial MoO 3 materials as high-performance cathodes for AZIBs.īoosting the capacity and stability of a MoO 3 cathode via valence regulation and polypyrrole coating for a rechargeable Zn ion battery Additionally, the fabricated Zn//MoO 3− battery obtains a maximum energy density of 233.6 W h kg −1 and a power density of 11.2 kW kg −1. In contrast, the original commercial MoO 3 sample only obtains a capacity of 99.3 mA h g −1 at 1 A g −1, and a cycling stability of 10% capacity retention over 500 cycles. The as-prepared MoO 3− cathode delivers a high reversible capacity of 212.4 mA h g −1 at 1 A g −1 with good cycling life (more than 75% capacity retention after 500 cycles). MoO 3 nanoparticles with low-valence-state Mo and PPy coating (denoted as MoO 3− are synthesized via a solvothermal method and subsequent electrodeposition process. In this work, we report an effective approach to first synthesise nanosized MoO 3− x materials to provide more active specific surface areas, while improving the capacity and cycle life of MoO 3 by introducing low valence Mo and coated polypyrrole (PPy). Nevertheless, owing to its undesirable electronic transport capability and poor structural stability, the practical capacity and cycling performance of MoO 3 are yet unsatisfactory, which greatly blocks its commercial use. Two different charge storage mechanisms were identified. Half cell measurements revealed electrode capacities up to 135 mAh/cm 3. A ZrO 2 blocking layer was used to prevent oxygen exchange with the atmosphere. Molybdenum trioxide (MoO 3) is emerging as a hugely competitive cathode material for aqueous zinc ion batteries (ZIBs) for its high theoretical capacity and electrochemical activity. open access Highlights Porous La 0.6 Sr 0.4 CoO 3 electrodes were tested in rechargeable oxygen ion batteries.
