About:Energy has characterised the P45B high-power battery cell from Molicel being used in several eVTOL designs (writes Nick Flaherty).
The P45B has a 10C pulse discharge capability and a 3C charge capability but can still provide a 242 Wh/kg nominal specific energy. Its low DC internal resistance is measured by About:Energy at 13.8 mΩ (7.86 mΩ for 0.2 seconds) bodes well for high C-rate use cases, particularly where the thermal management system is constrained.
