The invention relates to a cell arrangement (20) for a motor vehicle, comprising a plurality of cells (22), each having two cell electrodes (32a, 32b), a first side (24), a second side (26), a height (H) in the direction from the second side to the first side, and an openable venting opening (32c) for venting gas (40) from the associated cell in the event of thermal runaway, in the event of thermal runaway, the respective cell has at least one hot spot region (34) which is provided by at least one of the cell electrodes and/or by the vent opening, and the cell arrangement (20) has at least one filling layer (36) in which the section (A) of the respective cell is embedded in the height direction. At least one hot spot region is embedded in a filler layer which is formed by a filler (38) in order to thermally shield the cell in the event of thermal runaway.

    本发明涉及一种用于机动车的电芯装置(20),其具有多个电芯(22),电芯分别具有两个电芯电极(32a、32b)、第一侧(24)、第二侧(26)、在从第二侧到第一侧的方向上的高度(H)和可开启的排气开口(32c),该排气开口用于在热失控的情况下从相关的电芯中排出气体(40),相应的电芯在热失控的情况下具有至少一个热的热点区域(34),其由电芯电极中的至少一个电芯电极和/或由排气开口提供,电芯装置(20)具有至少一个填料层(36),在高度的方向上,相应的电芯的部段(A)被埋入在该填料层中。至少一个热的热点区域被埋入在填料层中,填料层通过填料(38)形成,用以在热失控的情况下使电芯热屏蔽。
