ABSTRACTTo better understand the condition of commercial batteries used in Tesla EVs and stationary applications under real performing situations, this article focuses on tracking the temperature of commercial batteries during varying cycling conditions. We have found evidence of significant impact of cycling methods on batteries in ionic conductivity, inner impedance development, and structural change in both cathode and anode electrodes, which will be further analyzed by electrochemical impedance spectroscopy technique in the following research.

Bare silicon and 20% yttria stabilized ceria on a silicon substrate are annealed. The annealed substrates are analyzed at varying temperatures using electrochemical impedance spectroscopy. The impedance data is fitted against appropriate equivalent circuits and the fitted data is characterized with an Arrhenius plot and a plot of the ionic conductivity against temperature. The 20% YDC sample is found to have a high ionic conductivity, and therefore should be studied further in order to determine the practicality of using YDC as an electrolyte.
