DMAIC in Lithium-Ion-Battery Production

DMAIC refers to a data-driven cycle of analysis steps used for improving, optimizing and stabilizing business processes with the steps Define, Measure, Analyze, Improve, and Control (DMAIC). In this paper, we will demonstrate the Define, Measure, and Analyze steps for the calendering step in Lithium-Ion-Battery Production. It appears that the measurement system is at least questionable. Moreover, we identified influential factors for thickness and porosity of the foil.
