For the CC C/20 coin cells show low variance in course and shoulders can be observed around 3.55 V and 3.65 V. For the pulsed formed coin cells, a similar but 100 mV shifted course between 3.55 V to 3.9 V can be calculated. Certain SEI products could benefit from this higher hysteresis and be preferably formed during the formation, also hinting towards potential differences in the SEI. The charge part of both reference and pulsed formation of PHEV1 cells in figure ) also reaches up to 2.5 mAh/cm 2 while showing low course variance for both formation strategies. Apart from a small dip in the reference cells referring to the sealing of the cells after initial degassing, the courses of reference and pulsed is similar to the coin cells including the same shoulders and the shift to higher voltages of the pulsed cells but only in the range of 3.55 V to 3.75 V. The discharge curve is nearly matching for CC and pulsed PHEV1 cells as well as the following vertical CV-part of the discharge but with a shorter CV part compared to the coin cells.
