The invention relates to a traction battery for a motor vehicle, comprising: a plurality of battery cells; a battery housing having a plurality of housing walls, wherein the housing walls surround a receiving space for receiving the battery cells and wherein at least one housing wall has a degassing unit for discharging hot gas of at least one battery cell from the receiving space; and a degassing collector provided outside the accommodation space and having a degassing space, the degassing space being expandable by the hot gas in order to accommodate the hot gas released from the accommodation space. The degassing space is defined by at least one housing wall of the battery housing having the degassing unit and a plate-like, at least partially thermally conductive heat shield. The heat shield is mounted so as to be linearly displaceable relative to the housing wall, can be pushed away from the housing wall by the hot gas in order to expand the degassing space, and is designed to cool the hot gas by distributing heat transported by the hot gas in the degassing space. The invention also relates to a motor vehicle.

    本发明涉及用于机动车的牵引电池,具有:多个电池单体;带有多个壳体壁的电池壳体,壳体壁包围用于容纳电池单体的容纳空间并且其中至少一个壳体壁具有用于将至少一个电池单体的热气体从容纳空间中排出的除气单元;和设置在容纳空间外部的具有除气空间的除气收集器,除气空间为了容纳从容纳空间中释放的热气体而能够通过该热气体膨胀。除气空间由电池壳体的具有除气单元的至少一个壳体壁以及板状的能至少部分地导热的热屏蔽部限定。热屏蔽部相对于壳体壁可线性移动地支承、能通过热气体被推离壳体壁以使除气空间膨胀,并且该热屏蔽部设计用于通过使由热气体运输的热量分布在除气空间中来冷却热气体。本发明还涉及机动车。
