Abstract
The production of lithium-ion batteries is highly complex and characterized by continuous as well as discrete material flows and processes. A first step towards controlling the complexity of battery production is to create transparency through data collection. Electrodes as one of the key elements in a battery cell play a decisive role for the battery performance. The allocation of production data to electrodes enables a detailed digital twin and an individual grading system. This paper presents a concept for the marking of electrode sheets and requirements on markers as well as on marking technologies due to boundary conditions.
