Central to the continued integration of Li-ion batteries, is a better understanding of their kinetics. Kinetics determine a batteries maximum rate of charge and discharge, which ultimately decides the material’s viability for different applications. Traditional methodologies for examining the kinetics in these complex systems suffer from interference at the electrode. This limits the utility of the data obtained from these measurements. In the Schougaard lab we are developing a system capable of probing these kinetics, without interference, employing dielectric spectroscopy. This unique system leverages prior research by Kuss et al. to provide in-situ measurements of battery materials during charging. The instrumentation also allows us to examine how these kinetics evolve with temperatures. This is specifically germane to examining current Li-ion battery materials and the effect phase transitions have on ionic transport.
