As the demand for energy increases, large-scale energy storage systems will be required. Rechargeable aqueous zinc battery (RAZB) systems are promising systems for large-scale electrochemical energy storage especially due to the appropriate reduction potential and low cost of zinc and inherently safer operation from the non-flammable aqueous electrolyte. Further, with appropriate materials selection, there is opportunity for high specific capacity. Specifically, the oxide and sulfide analogs of manganese and molybdenum-based positive electrode materials are appealing for RAZBs, as they are low cost and environmentally friendly, and can be produced through scalable synthesis methods. The electrochemical versatility of Mn- and Mo-based materials as redox-active materials and catalysts in RAZBs will be highlighted in this presentation, including materials synthesis, electrode preparation, characterization, and electrochemistry results.<br/><br/>References:<br/>(1) Kuang, Jason; Yan, Shan; Housel, Lisa M.; Ehrlich, Steven N.; Ma, Lu; Takeuchi, Kenneth J.; Takeuchi, Esther S.; Marschilok, Amy C.; Wang, Lei.“Manganese Molybdate Cathodes with Dual-Redox Centers for Aqueous Zinc-Ion Batteries: Impact of Electrolyte on Electrochemistry,” ACS Sustainable Chemistry & Engineering, 2022, 10(49), 16197-16213.<br/>(2) Dunkin, Mikaela R.; Kuang, Jason; Yan, Shan; King, Steven T.; Housel, Lisa M.; Ma, Lu; Ehrlich, Steven N.; Okasinski, John S.; Takeuchi, Kenneth J.; Takeuchi, Esther S.; Marschilok, Amy C.; Wang, Lei. “ Unveiling Charge Transport and Degradation Mechanisms of Aqueous Zn|α-MoO3 Batteries in Conventional Concentration and Water-in-Salt Electrolytes: A Multi-Modal In Situ and Operando Study,” Advanced Materials Interfaces, 2022, 9(29), 2201125.<br/>(3) Kuang, Jason; Renderos, Genesis D.; Takeuchi, Kenneth J.; Takeuchi, Esther S.; Marschilok, Amy C.; Wang, Lei; “Zinc-air batteries in neutral/near-neutral electrolytes,” Functional Materials Letters, 2021, 14(7), 2130012.
