A review of safety considerations for batteries in aircraft with electric propulsion

Shashank Sripad et al.

Summary: Modern aircraft designs use large battery packs for electric and fully electric aircraft, which require careful consideration of safety concerns unique to aviation. The main safety concerns related to batteries in this context include thermal issues and functional issues, which can lead to power loss and safety hazards. Internal short circuits and excessive heat generation are major risks for battery failure and potential fire hazards in aviation use.
