摘要： A battery module for an electrically-driven aircraft is disclosed. The battery module can house multiple battery cells and prevent a battery cell fire or explosion from one battery cell from damaging neighboring battery cells. The battery module includes: a housing; a plurality of cell tubes housing a plurality of battery cells, each cell tube having an elongated surface and being positioned in the housing spaced apart from each other; a heat absorbing member comprising a heat absorbing material, wherein the heat absorbing member is arranged between at least two neighboring cell tubes; and the heat absorbing material being configured to undergo a phase transition from an initial state of matter into a final state of matter when at least one of the plurality of cell tubes exceeds a predetermined temperature in case of explosion or fire of at least one of the plurality of battery cells.
