Problems solved by technology

Although the tubular plate has a long service life and a large capacity, it has complex production processes, low efficiency, low energy density, and low power. Due to the lack of connection between the lead cores, the tubular structure cannot conduct electricity once the lead core breaks, causing active substances. Inability to take advantage of disadvantages such as
Although the paste-coated plate has the advantages of simple process, high energy density, and high power, it has the disadvantage of short service life because the active material on the positive plate is easy to soften and fall off, causing the battery to fail.

Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 1 to Figure 5 As shown, a positive plate of a lead-acid battery of the present invention includes a grid frame body 1 with tabs, a lead paste 2 and an acid-resistant porous coating layer 3, and horizontal ribs 4 and vertical ribs are interlaced in the grid frame body 1 5. The grid frame body 1 is made of high corrosion resistance and high strength lead alloy material, which is preferably made by die-casting process or gravity casting and then rolling process. Slightly thicker than the transverse rib 4, this manufacturing process can enhance the structural strength of the grid frame 1 and ensure the stability of the positive plate shape and structure during the charging and discharging process of the lead-acid battery.

[0033] As a grid structure, the lead paste 2 is filled and coated in the grid frame 1 with the network struct...

Abstract

The invention discloses a positive plate of a lead-acid storage battery. The positive plate comprises a grid frame body with a tab, lead paste and an acid-resistant porous coating layer, wherein transverse and vertical ribs are arranged in the grid frame body in an intertwined manner; the lead paste, supported by a netty structure consisting of the transverse and vertical ribs, fills the grid frame body, and the acid-resistant porous coating layer is applied to the surface of the lead paste. By combining the structural advantages of a tubular plate and a paste plate, the grid positive plate formed avoids the phenomenon that active substances are softened and fall off, and the service life cycle is effectively prolonged. Meanwhile, the invention further provides a manufacturing method of the positive plate of the lead-acid storage battery. The method has the advantages of mechanical operation, high production efficiency and low input cost and is suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a positive plate of a lead-acid battery and a manufacturing method thereof. Background technique [0002] Lead-acid batteries are widely used due to their low price, simple manufacture, high capacity and stability. Lead-acid batteries for traction are widely used in airports, stations, warehousing, docks, industrial and mining enterprises and other fields. In recent years, due to the continuous growth of market demand, the role of lead-acid batteries has become increasingly prominent. In the production process of lead-acid batteries, the plate is the basic component, and its service life is directly related to the life of the lead-acid battery. The quality of the plate directly affects the quality of the lead-acid battery. Paste plates and tubular plates are two commonly used forms of plates. Although the tubular plate has a long service life and a large capacity, ...
