Electric Vertical Takeoff and Landing (eVTOL) aircraft represent a transformative advance in urban mobility, promising to decongest ground traffic and reduce urban transit times. However, the widespread adoption and operational efficiency of eVTOLs hinge significantly on advancements in battery technology. Solid-state batteries (SSBs) emerge as a pivotal innovation in this regard, potentially extending the range and enhancing the safety of eVTOLs.
