ECS and the ECS Pacific Northwest Section presented Prof. Xiulei “David” Ji’s webinar, “Aqueous Battery Chemistry: Considerations from a Reaction’s Perspective” on March 4, 2021. His answers to questions following the presentation are provided below. The webinar is now available for viewing.

Xiulei “David” Ji is an Associate Professor of Chemistry at Oregon State University, U.S. His research focuses on design principles of materials chemistry for electrochemical energy storage. Ji received a 2016 NSF CAREER Award and was a Web of Science Group Highly Cited Researcher in 2019 and 2020. He is currently an Associate Editor of Carbon Energy. He completed his PhD in Materials Chemistry at the University of Waterloo, Canada, in 2009. From 2010-2012, he was an NSERC Postdoctoral Fellow at the University of California, Santa Barbara, U.S.

“Aqueous Battery Chemistry: Considerations from a Reaction’s Perspective” summarizes five dimensions of considerations for the design of storage battery chemistries from a chemical reaction’s point of view. Different types of batteries including rocking-chair batteries, dual-ion batteries, and reverse dual-ion batteries are discussed. Ji also reviews recent conceptual advances on storage batteries that employ non-metal charge carriers such as proton, ammonium, halides, and superhalides.

The design of storage batteries entails a holistic view. This webinar summarizes five dimensions of considerations for the design of storage battery chemistries from a chemical reaction’s point of view. Electrode materials and ion charge carriers are the reactants; electrolytes are the reaction medium; battery configurations describe the operation fashion of the reactors; the electrode-ion chemical bonding reflects the nature of the chemical reaction, which affects the thermodynamic and kinetic properties of batteries. The permutations of these five dimensions result in ten unique approaches. The chemical-reaction nature of batteries can be a vantage that unifies rather than compartmentalizes a new paradigm of storage battery research. (more…)
