Abstract

A battery for an aircraft. The present embodiments further relate to an aircraft with at least one such battery. The battery may include a battery casing with a casing wall that forms an interior volume, a plurality of battery cells that is arranged in the interior volume, and a functional layer that is arranged at the casing wall between the plurality of battery cells and the battery casing. The functional layer may include an intumescent material that, in case of a breach of the battery casing, is adapted to ensuring flame containment within the interior volume and mitigation of uncontrolled heat and gas emission from the interior volume through the breach of the battery casing.
