Be it improving energy density or cycle life or reducing cost, understanding the failure modes of batteries in a non-destructive mode is critical during the design, product development, and manufacturing of lithium ion batteries. Electrochemical impedance spectroscopy (EIS) provides the ability to access and decouple the failure modes based on the processes’ time scale. Analysis of recorded EIS can be done either through phenomenological modelling or equivalent circuit modelling, with each having its own pros and cons.

This webinar reviews the basics of applying EIS for understanding the phenomena in lithium ion batteries, the experimental details and protocols, and the types of models with a few case studies. (more…)

Our world has no shortage of problems to solve. We now stand at a critical juncture for global action to address our most pressing challenges; from the COVID pandemic to climate change and so much more.

IBM has long recognized the urgency to find more sustainable solutions to tackle these problems (The Urgency of Science). For the first time in history we have the right tools at our disposable to do so. AI (artificial intelligence)—combined with advanced computing and access to enormous volumes of data via a secure and open hybrid cloud—can significantly accelerate the process of scientific discovery and the creation of more sustainable materials for use across a broad range of industries, including energy and batteries. 

Better batteries for cleaner energy

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.
