Problems solved by technology

[0010] (2) The process requirements for applying different lead pastes on both sides of the same current collector are too high, because the formulations of the positive and negative lead pastes are different, as long as the lead pastes on both sides of the current collector are in contact during the process, the electrode will be reduced. board quality or even scrapped
[0011] (3) The chemical reaction efficiency of the positive and negative lead paste active substances of the lead-acid battery is different, so the amount of lead paste that needs to be matched on both sides of the collector is different, that is, the two sides of the collector need to be coated with different amounts of lead paste, and the poles with different paste amounts are different. When the plate is cured, different temperature control procedures and curing time are required. If lead paste with different paste amounts is applied to both sides of the same current collector, the temperature control program and curing time reference for the plate curing will be at a loss, and it is difficult to ensure the synchronization of the positive electrode and the solidification time. The quality of the negative electrode

Embodiment 1

[0085] Embodiment 1, make the battery pack that 48V power is used, and the two poles of battery pack are drawn from the mount top, as Figure 13 Battery pack lead terminal configuration shown. The positive / negative pole of the battery pack is designed to extend from the single pole to the current collector 1 / 3 of the positive / negative plate as the lead 11 / 12, and is drawn from the top of the stand.

[0086] Firstly, a unipolar positive plate is fabricated, and the current collector 1 of the positive plate is made of a conventional lead alloy plate, which has a square plate structure of 150×150 mm and a thickness of 1.2 mm. One side of the current collector plate is flat, and the other side is pressed with 30 cylindrical teeth with a diameter of 1 mm and a height of 2 mm. The toothed side of the current collector is coated with conventional positive plate lead paste 2 . Similarly, the current collector 3 of the unipolar negative plate is made of a conventional lead alloy plate...

Embodiment 2

[0089] Embodiment 2, the lead pole of the battery pack of embodiment 1 and the external connection position are deformed and implemented, and the two poles of the battery pack are drawn from the two ends of the side of the seat frame, that is, the lead poles of the pole plates used for the positive terminal 11 / negative terminal 12 are Lead out from the side design of 1 / 3 of the collector, such as Figure 14 shown. The rest of the data and manufacturing method are similar to those of Example 1, and the obtained 48V10Ah battery pack is similar to that of Example 1.

Embodiment 3

[0090] Embodiment 3. The shape of the battery pack in Embodiment 1 and the shape of the inner plates were deformed, and the current collectors of the positive and negative electrodes were changed from a square structure of 150×150 mm to a circular structure with a radius of 85 mm. In order to make the combination and installation of the dipole pairs convenient, the current collecting surfaces of the positive and negative electrodes are made into several pieces of concavity and convexity, the concave surface of the positive electrode current collector is complementary to the convex surface of the negative electrode current collector, and the rest of the data and manufacturing method are similar to those in Example 1. The obtained 48V10Ah battery pack is similar to the battery pack in Example 1.
