In cooperation with ZSW the pulsed formation protocol was scaled up to application orientated cell format of prismatic 25Ah PHEV1 format cells. For these tests the pulse configuration with C/5.7 was used as it shows low variance and good results before. Figure presents the voltage over the area specific capacity of CC and pulsed formation for 5 cells of coin cells in a) and PHEV1 cells in b). For coin cells presented in Figure a) the areal capacity rises around 2.5 mAh/cm 2 with smaller differences between pulsed and CC formation despite the higher pulse current.
