Coin cells (CR2032) were automatically assembled by the in-house developed robotic AutoBASS-system in a nitrogen-filled glovebox with H2O and O2 levels below 0.1ppm . The coin cell parts were washed with isopropanol in an ultrasonic bath and dried in an oven at 80°C overnight before the assembly. The NMC (622) cathodes were cut in 14 mm discs, graphite anodes in 15 mm discs and Celgard ® 2325 separator(25 µm microporous trilayer Membrane (Polypropylene / Polyethylene/ Polypropylene) in 16 mm discs. 35 µL of 1M LiPF6 in EC:EMC (3:7 wt:wt) from manufacturer E-Lyte was used as electrolyte. The nominal capacity cnom for all cells was calculated to be 3.28 mAh based on the areal cathode discharge capacity of 2.14 mAh/cm 2 at 1C discharge given by the supplier ZSW. All cells went through a 24 h wetting at a controlled temperature of 20°C before starting tests with the anode facing down. Tests were performed on an Arbin battery cycler (LBT21084-5).
