The meshed polar plate of the lead-acid battery comprises a pole lug, a grid border and grid meshes arranged in the grid border. In particular, the grid meshes consist of main ribs and auxiliary ribs; wherein the main ribs are connected to form a cellular network; and the auxiliary ribs are connected to form a regular hexagonal radiating grid pattern within the cellular network. The utility model has the advantages of high utilization rate of grid meshes on the polar plate, uniform consumption and uniform heat generation. Simultaneously, the utility model can effectively eliminate the expansion and deformation of the polar plate, ensure the electric performance of the lead-acid battery, and prolong the service life of the lead-acid battery.

Description

The netted pole plate of lead acid accumulator

Technical field

The utility model relates to the netted pole plate of paste spread type that a kind of lead acid accumulator is used.

Background technology

Lead acid accumulator is cheap, be widely used, and is the storage battery of current production rate maximum.The lead acid accumulator critical piece has: positive plate, negative plate, electrolyte, dividing plate, battery case etc. also have some accessories such as terminal, intercell connector, blow-cook etc. in addition.And that positive/negative plate generally can be made is netted, with the augmenting response area.Have the electrode plate structure of general lead acid accumulator now, as shown in Figure 1, lug is arranged on the grid frame, and be provided with aperture plate in the grid frame, the form of aperture plate is: horizontal network equidistantly distributes, portrait network points to lug, radially distributes, and portrait network and horizontal network form the trapezium grid shape of interconnection jointly.Such pole plate, find following problem in use for some time: 1) utilance of the active material of aperture plate each several part is inhomogeneous: near the active material utilization height the lug on the aperture plate, the aperture plate seriously corroded, and maintain the original state away from the position of lug; 2) the dilatancy situation is serious: because grid shape does not have stability under loading, and active material utilization is inhomogeneous to cause each position heating of aperture plate inhomogeneous, so the dilatancy of 8～10mm can take place even reach for the transverse width of grid frame and vertical height.Use the storage battery of this pole plate, its useful life and serviceability obviously can not arrive optimization.

Summary of the invention

The purpose of this utility model be to provide a kind of active material utilization high and evenly, structural capacity is strong, and then can improve the novel pole plate of service life of lead accumulator and performance.

For achieving the above object, the utility model has been taked following technical scheme:

The netted pole plate of lead acid accumulator comprises lug, grid frame and is arranged on the interior aperture plate of grid frame that especially, described aperture plate is connected and composed by main rib and secondary rib; Described main rib connects and composes Cellular Networks; Described secondary rib connects and composes the grid line in the honeycomb grid.

Grid line in the honeycomb grid that described secondary rib connects and composes is that regular hexagon is radial, or,

Grid line in the honeycomb grid that described secondary rib connects and composes is that hexagon is radial.

The area of section of described main rib equals the area of section of secondary rib, and perhaps, the area of section of described main rib is greater than the area of section of secondary rib.

The cross sectional shape of secondary rib can have multiple variation.

Be reinforced company's relay, the radial grid line of described regular hexagon, its regular hexagon have one group of symmetric angle to be connected to each other.

Described aperture plate has also comprised the additional rib of supplemental support effect.

Each point on the aperture plate that above technical scheme constitutes is more than existing common aperture plate to the passage of lug, thereby utilance is both high also even, and it is also even to generate heat, and the syndeton power of honeycomb grid is fine, can effectively eliminate the dilatancy problem of plate.

Technique effect of the present utility model is: the utilance height of aperture plate on the pole plate, consume evenly, it is also even generate heat, can effectively eliminate the dilatancy problem of pole plate simultaneously, makes lead acid accumulator can bring into play better electrical performance and acquisition longer useful life.
