Embodiment 1
[0031] A secondary battery such as figure 1 As shown, it includes a cover plate 1 , a connector, a tab lead-out device, a second gasket 3 , and a winding core 7 . The tab lead-out device includes an insulating gasket 6 and a first gasket 5, wherein the insulating gasket 6 forms an insulating layer, and the first gasket 5 forms a conductive layer. The connecting piece includes a nut 2 and a screw 502 fixed on the first washer. The battery plate is wound into a cylindrical core 7, and there are multiple tabs 4 protruding from the core 7 at both ends. The tabs at one end are positive tabs, and the other ends are negative tabs. The connecting structure of the cover plate is the same.
[0032] The insulating spacer 6 is circular and is placed on the end face of the winding core 7. The structure of the insulating spacer 6 is as follows: figure 2 As shown, a hole 601 is opened thereon, and the hole 601 is a discontinuous sector. A first gasket 5 is stacked above the insulating g...
Embodiment 2
[0038] A secondary battery, including a cover plate, a connector, a tab lead-out device, a second gasket, and a winding core, the difference from Example 2 is that the tab lead-out device is a composite of an insulating layer and a conductive layer Structure. Such as Figure 7 As shown, the tab lead-out device is divided into upper and lower layers, the upper layer is a conductive layer, and the lower layer is an insulating layer, and the tab passes through the hole on the tab lead-out device from below the insulating layer and is welded above the conductive layer.
Embodiment 3
[0040] A secondary battery, including a cover plate, a connector, a tab lead-out device, a second gasket, and a winding core. The difference between it and Embodiment 2 is that there is no hole on the tab lead-out device, such as Figure 8 As shown, the tab protrudes from the edge of the tab lead-out device from below the insulating layer and is welded above the conductive layer.
