The invention discloses a cover assembly, a battery cell shell, a battery cell, a battery pack, an automobile and a correction method, a cover plate and a pole are compositely connected with a transition connection material, and the pole and the cover plate are connected through the respective composite transition connection material, so that a rigid connection mode of the pole and the cover plate in the prior art is improved into a flexible connection mode; therefore, the height of the pole protruding out of the cover plate can be reduced, the effective space of the battery cell is not occupied, the overall height space of the battery cell is small, and the energy density of the whole battery pack in a limited volume can be improved.
本发明公开了一种盖组件、电芯壳体、电芯、电池包、汽车和修正方法,通过在盖板和极柱上均复合连接过渡衔接材料,极柱和盖板之间通过各自复合的过渡衔接材料来进行连接,以将现有技术中极柱与盖板的刚性连接方式改进为柔性连接,这样可以降低极柱凸出盖板的高度,从而不会占用电芯有效空间,电芯整体高度空间占用小,这样能够提高整体电池包在限定体积内的能量密度。
