Embodiment 1

[0058] Step 1: On the frame of the side negative plate, the length of 1mm from the frame of the side negative plate is used as the bending point, and the tabs at this distance have no horizontal offset;

[0059] Step 2: Bending the tab at the bending point in step 1, the bending angle is 120°, and the length B of the bent tab in the vertical direction is 4mm;

[0060] Step 3: On the basis of step 2, bend the upper part of the tab of the side negative plate. The horizontal offset distance of the tab of this section is 0.5mm, and the tab is pinched to complete.

Embodiment 2

[0062] Step 1: On the frame of the side negative plate, the length of 3mm from the frame of the side negative plate is used as the bending point, and the tabs at this distance have no horizontal offset;

[0063] Step 2: Bending the tab at the bending point in step 1, the bending angle is 140°, and the length B of the bent tab in the vertical direction is 4.5mm;

[0064] Step 3: On the basis of step 2, bend the upper part of the tab of the side negative plate. The horizontal offset distance of the tab of this section is 1mm, and the tab is pinched to complete.

Embodiment 3

[0066] Step 1: On the frame of the side negative plate, the length of 2mm from the frame of the side negative plate is used as the bending point, and the tabs at this distance have no horizontal offset;

[0067] Step 2: Bending the tab at the bending point in step 1, the bending angle is 135°, and the length B of the bent tab in the vertical direction is 4.2 mm;

[0068] Step 3: On the basis of step 2, bend the upper part of the tab of the side negative plate. The horizontal offset distance of the tab of this section is 0.8mm, and the tab is pinched to complete.

[0069] Another embodiment of the present invention discloses a storage battery, which includes a casing and a battery electrode group disposed inside the casing. The tabs of the negative plate on the side of the battery electrode group are kneaded by the method of Embodiments 1 to 3.

[0070] Specifically, the battery electrode group in this embodiment includes positive plates, negative plates, positive tabs, negativ...

Abstract

The invention relates to a battery and a method for pinching a tab on the side negative electrode plate of a battery, and belongs to the technical field of battery manufacturing to solve the problem that the effect of pinching the tab on the side negative electrode plate is unstable and affects the battery life in the prior art. The method for pinching the tab on the side negative electrode platecomprises the following steps of 1: selecting a bending point over a side negative electrode plate upper frame, wherein the bending point is a certain distance to the side negative electrode plate upper frame and the tab in the distance is not horizontally offset; 2, bending the tab at the bending point in the step 1, and controlling a bending angle and the length of the bent tab in the vertical direction; and 3, on the basis of step 2, bending the upper part of the tab on the side negative electrode plate, and controlling the horizontal offset distance of the tab in this section to complete the pinching. The battery includes a casing and a battery pole group disposed inside the casing, and the tab on the side negative electrode plate of the battery pole group is pinched by the above method. The method improves the effect of pinching the tab on the side negative electrode plate and prolongs the service life of the battery.

Description

technical field [0001] The invention relates to the field of storage battery manufacturing, in particular to a storage battery and a method for pinching tabs on side and negative plates of the storage battery. Background technique [0002] With the implementation of the new national standard for lead-acid batteries, improving the specific energy of batteries has become an urgent task for the lead-acid battery industry. [0003] Among them, changing the battery from bridge welding to direct connection welding is a feasible solution to increase the specific energy of the battery, which not only reduces the amount of lead used in the busbar, but also reduces the length of the busbar, and the internal resistance of the battery is reduced. However, in the actual production process, the battery semi-finished products after direct continuous casting and welding are prone to the problem of side negative board glue climbing in the process of glue sealing, the utilization rate of acti...
