Metallic foils for battery electrodes (BE) require highly developed handling techniques to avoid contaminating or damaging the substrate. Additionally, deposition accuracy and cycle times are key requirements for scalable and efficient assembly processes. Within this context, the present research investigates material-adapted electrostatic handling of metallic foils. The newly developed electrostatic gripper (ESG) utilizes Coulomb forces, a low-frequency AC power supply and a polyethylene (PE) dielectric material, enabling high-quality handling without external media consumption. Experimental investigations demonstrate safe handling as well as fast and accurate positioning of sample BE based on lithium foils, opening up future possibilities for industrial use.
