Use of a High Energy-Dense Li Anode Cell for an eVTOL Application

Abstract

Electric vertical take-off and landing (eVTOL) aircraft require sufficient electric energy to complete their missions and sufficient electric power for hover conditions (including standard and degraded modes of operation). When using current battery technology, the energy storage system constitutes a significant portion of the vehicle mass, thereby significantly limiting vehicle performance. Advanced cell technologies using solid lithium (Li) anode technology have the potential to increase energy density as compared to traditional cell-based on graphite anodes. Efforts to develop battery solutions using Li anode technology for an eVTOL application demonstrate reduced battery weight while achieving near-term performance objectives.
