The Electrochemical Society hosted Prof. Raphaële J. Clément’s live online webinar, “From order to disorder: NMR insights into ionic conduction in battery materials,” on October 27, 2021. Below are answers to questions posed during the presentation.

NOTE: Registration is required to view the webinar.

Raphaële Clément is an Assistant Professor in the Materials Department at the University of California, Santa Barbara (UCSB), U.S. She received her PhD in Chemistry in 2016 from the University of Cambridge, UK, working under the supervision of Prof. Clare Grey. Her doctoral work focused on the study of layered sodium transition metal oxide cathodes for Na-ion secondary batteries. She then joined Prof. Gerbrand Ceder’s group at the University of California, Berkeley (UC Berkeley), U.S., focusing on cation-disordered rock salt oxyfluorides for Li-ion battery applications. She joined the UCSB faculty in 2018. Her primary research focus is the development and implementation of magnetic resonance techniques (experimental and computational) for the study of battery materials and beyond, with a strong emphasis on operando tools. She is an Associate Editor for Battery Energy, a new open access journal by Wiley. (more…)

Electric VehicleThe U.S. Department of Energy (DOE) recently announced $209 million in funding for 26 new laboratory projects focusing on electric vehicles, advanced batteries, and connected vehicles. DOE’s Argonne National Laboratory introduced Li-Bridge, a new public-private partnership to bridge gaps in the domestic lithium battery supply chain. Advanced lithium-based batteries play an integral role in 21st century technologies such as electric vehicles, stationary grid storage, and defense applications that are critical to securing a clean energy future. The projects support goals to make the United States a global leader in electric vehicle and battery innovation; advance the development of these technologies to save families money; lower carbon pollution; and create high-quality jobs.

During battery (dis)charging, lithium (de)intercalation in electrodes is usually spatially non-uniform across multiple length scales. Such a phenomenon is a major impediment to battery performance and life as it causes energy under-utilization and induces over-(dis)charging, etc. While reaction heterogeneity is often attributed to mass transport limitation, this talk highlights the important roles of thermodynamic factors including elastic energy and phase transformations, the understanding of which is important for the development of mitigation strategies. Through combined modeling and characterization, how stress could destabilize the lithium (de)lithiation front in single crystalline and polycrystalline intercalation compounds is elucidated. Also, a fundamental driving force for dendrite growth on the lithium metal anode during electrodeposition is provided. Stress relief thus offers a promising approach to improving reaction uniformity at the particle level. At the cell level, the reaction distribution that within the porous electrode is strongly influenced by how the electrode’s equilibrium potential varies with the state of charge, is discovered. Two types of prototypical reaction behavior emerge from common electrode materials with significant impact on the thick electrode performance. This finding leads to an efficient analytical model for optimizing battery configurations in place of common battery cell simulations. (more…)

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…)
