Identification of ageing process using Electrochemical Impedance Spectroscopy

Within this project, systematic ageing tests, measurements of impedance during the ageing tests and an analysis of the major ageing effects and processes in lithium batteries have been performed. Based on these activities it was possible to understand better the impedance spectra and to correlate them with ageing processes inside the batteries. Therefore it is now possible to use the impedance spectroscopy as an important tool to develop and analyse lithium batteries with regard to ageing.
