Battery-powered aircraft and drones have unique requirements to ensure that the batteries used in these vehicles perform to their highest capabilities yet do not pose a safety hazard to passengers or equipment. The biggest issue when dealing with aviation batteries has to do with heat. Charging, discharging, or even normal flight operations can produce heat in amounts that will cause hot spots in the cells. This uneven distribution of heat results in the shortening of useful cell lifetime or, in extreme cases, can lead to a cascading failure where every cell in a module catches fire in a thermal propagation event, also known as thermal runaway.
Flexible graphite heat spreaders efficiently eliminate hot spots from the cells and then spread them to an outside heat sink. Building on a long and successful history in the EV and maritime industries, flexible graphite is a lightweight, thin, and permanent thermal solution. GraFoil® graphite gaskets efficiently seal battery modules to prevent the escape of hot gases while remaining flexible and reusable.
