Problems solved by technology

[0003] However, there are still some problems in the existing above-mentioned pole plates in use: 1. The grid of the pole plate is in the shape of a fence. When energized, the current flows through the grid, and the active material in the through hole on the grid Because the resistance is large and the current flowing through is small, the reaction utilization rate of the active material at this place is low; 2. Because the plate needs to be treated with acid, curing and other processes when filling the active material, so the existing The grid of the electrode plate cannot be made of lead, which has the best charge and discharge effect, and can only be made of lead alloy with relatively high strength. However, once the lead alloy plate is deeply discharged, the alloy elements of the positive grid will be released. It directly affects the battery life and capacity, so its service life is also extremely short, generally around 200 to 300 times

Embodiment 1

[0029] like figure 1 As shown, the high lead ion energy plate includes a plate-shaped main body and a tab 4 for connecting with the positive pole or negative pole of the storage battery. The main body includes a conductive plate 1 and a The grid 2 on the side and the tab 4 are connected to one end of the conductive plate 1 . Wherein, the grid 2 and the conductive plate 1 have the same size and are stacked correspondingly. A plurality of through holes 3 are opened on the grid 2 along a direction perpendicular to the conductive plate 1 , and the surface of the grid 2 and the through holes 3 are filled with active materials 5 in contact with the conductive plate 1 . In this embodiment, the active material 5 is a plate material that generates electrical energy through a chemical reaction when the battery is discharged, and returns to its original composition when the battery is charged.

[0030] like image 3 As shown, the conductive plate 1 is in the shape of a plate as a whol...

Embodiment 2

[0037] like figure 2 and Figure 4 As shown, the technical solution of this embodiment is substantially the same as that of Embodiment 1, the difference is that the tab 4 connected to the conductive plate 1 is in the shape of a plate, and the width of the tab 4 is the same as that of the conductive plate 1 . When the pole plate of this embodiment is applied to a unipolar storage battery, its stacking method and sequence are the same as in Embodiment 1, but because the tab 4 is in the shape of a plate, the conductive plate 1 with negative grids on both sides and the conductive plate 1 on both sides Two sides of the inner core of the battery are separately provided for the tabs 4 on the conductive plate 1 of the positive grid.

[0038] In addition, the high lead ion energy pole plate can also be applied to bipolar storage batteries. At this time, the stacking order of the battery inner core of the bipolar battery is as follows: rubber layer (this layer can also be omitted du...

Description

technical field [0001] The invention belongs to the technical field of accumulators, and relates to a pole plate of a lead-acid battery, in particular to a pole plate with high lead ion energy. Background technique [0002] The pole plates in the existing battery case generally include a fence-shaped grid made of conductive material, lead paste and metal tabs connected to the grid, wherein the lead paste is filled on the surface of the grid and the grid The active material that can carry out the redox reaction is formed after acid leaching, curing and other processes in the through hole on the battery, and the metal tab is connected to the positive pole or negative pole of the battery through the bus bar. When the battery is connected to the circuit and used, the fence-shaped grid is energized, and the active material coated on the grid reacts through the electrolyte to realize charging or discharging. This kind of plate has dominated the history of lead-acid batteries for ...
