Then all the tabs 121 penetrate through the mounting holes 1111 in the insulating support 111 to complete the mounting of the insulating support 111; then, a positive tab and a negative tab (it should be understood that the tabs 121 subjected to the bending operation are both pointed out of the mounting holes 1111) on the middle cell can be respectively bent towards the two sides of the cell; in one case, the positive tab 121 on the middle cell is bent toward the first cell, and at this time, the negative tab on the first cell is also bent toward the middle cell, and the positive tab and the negative tab after being bent can be partially overlapped together, specifically, when the tab 121 is bent, the tab 121 can be attached to the second side surface of the insulating support 111 to increase the overlapped portion of the positive tab and the negative tab overlapped together, thereby ensuring sufficient contact between the tabs 121 and providing reliable electric transmission between the two cells.

Specifically, when two tabs 121 with the same position on two adjacent battery cells in the width direction of the battery cell respectively penetrate out of the first mounting hole 1111a and the second mounting hole 1111b, and are stacked on the second side surface of the insulating support 111 between the first mounting hole 1111a and the second mounting hole 1111b, the hollow portion 1112 between the first mounting hole 1111a and the second mounting hole 1111b is located just under the two stacked tabs 121, even if the two overlapped tabs 121 are partially in a suspended state, so that when the welding operation between the two stacked tabs 121 is subsequently performed, the two overlapped tabs 121 are ensured not to be in contact with the insulating support 111, and the insulating support 111 is protected. In practice, to further ensure that the welding operation does not damage the insulating support 111, the opening of the hollowed-out portion 1112 may be designed to be slightly larger, so that the portion to be welded between the two stacked tabs 121 is located directly above the hollowed-out portion 1112.
