** Building three electrode laboratory cells with metallic lithium reference electrode: Three-electrode electrochemical tests were carried out in ECC-PAT-Core test cells, supplied by EL-CELL GmbH. From a battery cell opened at discharged state, the electrodes were harvested. To achieve electrical contact from the backside, the coating was removed from one of the sides of the electrode sheets, and discs were punched out. Besides the electrodes, a lithium reference electrode, integrated into a glass fiber 260 µm separator, a 200 µm plunger, and 150 µl of the electrolyte LP57 (1M LiPF<sub>6</sub> in EMC/EC solution, with a weight ratio of 7:3, supplied by BASF) was used to build a test cell. Thereby, the individual electrodes’ potentials became accessible for investigation. | ** Building three electrode laboratory cells with metallic lithium reference electrode: Three-electrode electrochemical tests were carried out in ECC-PAT-Core test cells, supplied by EL-CELL GmbH.

Characterization data was obtained from the following sources: | |||
* Cell tests / Cycling at Fraunhofer ISC during public funded projects and PhD Thesis project of Lukas Gold | * Cell tests / Cycling at Fraunhofer ISC during public funded projects and PhD Thesis project of Lukas Gold | ||
* Electrochemical tests: All electrochemical tests were conducted within a controlled environment at a constant temperature of 25 °C. Depending on space requirements and duration of the experiment, a Vötsch VT<sup>3</sup> 4018-S, a Vötsch VT 4021-S, a Weiss WKL 34/70, or a Memmert IPP 260<sup>PLUS</sup> were used to control ambient conditions. A Maccor Series 4000 galvanostat was used to perform cycling tests. | * Electrochemical tests: All electrochemical tests were conducted within a controlled environment at a constant temperature of 25 °C.
