This thesis project investigates the best testing quality control setup to measure the adhesion of the interface coating/metallic foil of electrodes in lithium-ion battery cells. In fact, there is no specific standard (ISO/ASTM) for this kind of adhesion testing to date. Firstly, a review of the literature concerning lithium-ion batteries and adhesion test methods is given. The importance of the coating adhesion of electrodes is described. In fact, it is a critical mechanical property of the electrodes as it affects the electrochemical lifetime, cycle performance and stability of battery cells. Secondly, three different tests were studied in more detail: the 180° peel test, the 90° peel test and the z-direction pull test.
