Lithium-ion batteries (LiBs) industrial production requires a large number of skills in many scientific fields. The process starts from the electrodes manufacturing and ends with the battery formation. Electrodes cutting is undoubtedly a crucial step as it could turn out to be one of the bottlenecks for a fast and efficient production. In this paper, we propose a quicker and cheaper method to evaluate the electrical contact resistance between coating and current collector (R Contact ) by using impedance spectroscopy (EIS) to compare different cutting methods. The results show the existence of a cutting technique—cell performance relationship.
