Physically based Impedance Modelling of Lithium-Ion Cells

Download or read book Physically based Impedance Modelling of Lithium-Ion Cells written by Illig, Joerg and published by KIT Scientific Publishing. This book was released on 2014-09-19 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, a new procedure to analyze lithium-ion cells is introduced. The cells are disassembled to analyze their components in experimental cell housings. Then, Electrochemical Impedance Spectroscopy, time domain measurements and the Distribution function of Relaxation Times are applied to obtain a deep understanding of the relevant loss processes. This procedure yields a notable surplus of information about the electrode contributions to the overall internal resistance of the cell.
