Advancing the Research on Metal-ion Batteries with Magnetic Resonance

From Feb 7 2023
Advancing the Research on Metal-ion Batteries with Magnetic Resonance

Summary

Metal-ion batteries have changed our everyday lives. The research on the electrode materials for metal-ion batteries is the key to improving the performance of the battery. Magnetic resonance, including nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR), has been continuously improved during the past three decades and has gradually become one of the important technologies to study the structure-performance relationship of electrode materials.

This webinar will help to grasp the important value of NMR and EPR techniques for battery research, which will promote the further development of advanced magnetic resonance technology. Prof. Hu will present unique examples of in-situ EPR and EPR imaging methods to study bulk and dendritic lithium deposits, dissolution of Cr-ions in Na-batteries, detection, and monitoring oxygen species, such as molecular and singlet oxygen in new cathode materials. A novel approach of using EPR employed together with NMR to analyze and understand electrochemical reaction mechanisms and structural electrode changes is the key to further improving battery performance.

Speakers

Prof. Bing-Wen Hu

Shanghai Key Laboratory of Magnetic Resonance, East China Normal University

Prof. Hu studied at Fudan University from 1999 to 2006, and from 2006 to 2009 at the French Ultra high-Field Nuclear Magnetic Resonance Research Center at the University of Lille, France, where he was engaged in the development of new NMR methods. After his return to China, he focuses on the development of new technologies for NMR and EPR and their application in lithium-ion and sodium-ion battery systems. He has published more than 150 articles. He was a recipient of YuanZhi EPR (CHINA) award in 2022. He is currently the deputy director of the Shanghai Key Laboratory of Magnetic Resonance. He now holds a position of Full Professor at East China Normal University.

Dr. Sylwia Kacprzak

Market Product Manager

Sylwia Kacprzak received her M.Sc. degree in Chemistry at the University of Maria Curie Sklodowska in Poland. Her EPR career began during her Ph. D. research at the University of Würzburg with a focus on investigations of the electron paramagnetic resonance parameters of bioradicals by density functional methods. Two postdoctoral positions followed at FU Berlin and University of Freiburg, where she gained extensive expertise in CW-EPR and FT-EPR techniques taking advantage of her theoretical background. In 2016, Sylwia joined Bruker as an Applications Scientist.
