[0019] The present invention is further described below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 2 As shown, the present invention is an AGM separator 1000 for a lead-acid battery, having a length direction X, a width direction Y and a height direction Z, wherein the length direction X and the width direction Y form a front surface 1 and a rear surface 2, the width direction Y and the height direction Z form an upper surface 3 and a lower surface 4, and the length direction X and the height direction Z form a left surface 5 and a right surface 6. The AGM separator 1000 forms front and rear pores 100 penetrating the front surface 1 and the rear surface 2, and the front and rear pores 100 are oxygen recombination channels when the lead-acid battery is charged. Figure 1 , Figure 6 , Figure 7 As shown, the dotted line 204X indicates that when the separator 1000 covers the positive electrode plate 200, the position of the transverse rib 204 of the grid 201 is projected on the front surface 1 or the rear surface 2 of the separator 1000 along the width direction Z of the separator 1000, Figure 1 , Figure 6 , Figure 7 Two dotted lines 204X are shown in the figure. The dotted line 205X ​​indicates that when the separator 1000 covers the positive electrode plate 200, the vertical ribs 205 of the grid 201 are projected onto the front surface 1 or the rear surface 2 of the separator 1000 along the width direction Z of the separator 1000. Figure 1 , Figure 6 , Figure 7 Two dotted lines 205X ​​are shown in FIG. The length direction of the AGM separator 1000 is greater than the width direction, and the width direction is greater than the height direction.

[0021] like Figure 3As shown, the front and rear pores 100 have an inner surface 101, the front and rear pores 100 are formed with a center line 103, and a hydrophobic material 102 for enhancing the hydrophobicity of the front and rear pores 100 is formed on the inner surface 101 of the front and rear pores 100. Since the hydrophobic material 102 is formed on the inner surface 101 of the front and rear pores 100, during charging, it is beneficial for oxygen to pass through the front and rear pores 100 from the positive electrode to the negative electrode, thereby improving the efficiency of oxygen recombination, reducing water loss, and ensuring the life of the AGM lead-acid battery.

[0022] like Figure 4-Figure 5 As shown, the positive electrode plate 200 coated with the AGM separator 1000 of the present invention includes a grid 201, and the grid 201 includes a wide surface 202 and a narrow surface 203. The wide surface 202 is composed of ribs, and the ribs include horizontal ribs 204 and vertical ribs 205. When the AGM separator 1000 coats the positive electrode plate 200, the center line 103 of the front and rear pores 100 is perpendicular to the wide surface 202 of the grid 201.

[0023] A first embodiment of the present invention is as follows Figure 6 As shown, the front and rear apertures 100 include a first aperture 100a and a second aperture 100b, and the center line of the first aperture 100a ( Figure 6 The center line of the second pore 100b (not shown) does not pass through the ribs of the grid 201 after extending, that is, the first pore 100a is not located on the dotted line 204X and the dotted line 205X, and the center line of the second pore 100b ( Figure 6 The first pore 100a is located on the dotted line 204X or the dotted line 205X. The volume of the first pore 100a is greater than the volume of the second pore 100b. It is best that the average pore diameter of the first pore 100a is greater than the average pore diameter of the second pore 100b. Compared with the second pore 100b, during charging, the first pore 100a is conducive to oxygen passing through and reaching the negative electrode from the positive electrode, and the oxygen recombination efficiency is high. The second pore 100b is located on the dotted line 204X or the dotted line 205X. The volume of the second pore 100b is smaller than that of the first pore 100a, which can reduce the corrosion of the grid ribs. The center line of the second pore 100b ( Figure 6 The second pore 100b extending through the transverse rib 204 of the grid 201 is a second transverse pore 100b1. The center line of the second pore 100b ( Figure 6The second pores 100b extending through the vertical ribs 205 of the grid 201 (not shown) are second vertical pores 100b2. The size relationship between the volume of the second vertical pores 100b2 and the volume of the second transverse pores 100b1 can be set arbitrarily as needed. Similarly, the size relationship between the average pore diameter of the second vertical pores 100b2 and the average pore diameter of the second transverse pores 100b1 can be set arbitrarily as needed. The second transverse pores 100b1 are arranged in sequence along the width direction Y of the AGM separator 1000 to form an arrangement direction along the width direction of the AGM separator. In the arrangement direction formed by the second transverse pores 100b1, it is best to form a partition layer transverse pore group that partitions the upper and lower parts of the AGM separator 1000 in the length direction X, such as Figure 6 As shown, the number of transverse pore groups of the partition layer set in the length direction X can be set according to the number of transverse ribs of the grid, and can be equal to the number of transverse ribs of the grid. Preferably, the volume of the second vertical pore 100b2 is larger than the volume of the second transverse pore 100b1, and the average pore diameter of the second vertical pore 100b2 is larger than the average pore diameter of the second transverse pore 100b1. Preferably, the volume of the second vertical pore 100b2 is larger than the volume of the second transverse pore 100b1. In this way, the corrosion ability of the second transverse pore 100b1 to the transverse ribs of the grid is less than the corrosion ability of the second vertical pore 100b2 to the grid, and the acid stratification phenomenon is also reduced. In order to better avoid the acid stratification phenomenon and better reduce the corrosion of the transverse ribs of the positive grid, it is best that the volume of the second transverse pore 100b1 is 0, that is, the average pore diameter of the second transverse pore 100b1 is 0, that is, the interior of the second transverse pore 100b1 is completely filled with hydrophobic material 102. The volume of the second vertical pore 100b2 is preferably larger than the volume of the second horizontal pore 100b1 and smaller than the volume of the first pore 100a, so that the second vertical pore 100b2 can reduce the corrosion of the vertical ribs of the grid while retaining a part of the oxygen recombination capacity, and also ensure the flow of the acid in the Y direction.

[0024] A second embodiment of the present invention is as follows Figure 7 As shown, the front and rear apertures 100' include a first aperture 100a' and a second aperture 100b', and the center line of the first aperture 100a' ( Figure 7 The center line of the second pore 100b' (not shown) does not pass through the ribs of the grid 201 after extending, that is, the first pore 100a' is not located on the dotted line 204X or the dotted line 205X, and the center line of the second pore 100b' ( Figure 7The second pore 100b' includes a second transverse pore 100b1' and a second vertical pore 100b2'. The center line (not shown) of the second transverse pore 100b1' extends through the transverse rib 204 of the grid 201. The center line (not shown) of the second transverse pore 100b1' extends through the transverse rib 204 of the grid 201. The center line ( Figure 7 The second vertical pores 100b2' include second vertical partition pores 100b21' and second vertical non-partition pores 100b22', and the first pores 100a' include partition pores 100a1' and non-partition pores 100a2'. The partition pores 100a1' are arranged in sequence along the width direction Y of the AGM separator 1000 to form an arrangement direction along the width direction of the AGM separator, and together with the second vertical partition pores 100b21' located in the arrangement direction of the partition pores 100a1', form a partition layer pore group that separates the upper and lower parts of the AGM separator 1000 in the length direction X, as shown in FIG. Figure 7As shown, the number of the pore groups of the partition layer in the length direction X is set as needed, the volume of the second vertical non-partitioning pore 100b22' and the volume of the second horizontal pore 100b1' of the second pore 100b2' are greater than the volume of the partitioning pore 100a1' and the volume of the second vertical partitioning pore 100b21' of the first pore 100a', and are smaller than the volume of the non-partitioning pore 100a2' of the first pore 100a'. It is best that the diameter of the second vertical non-partitioning pore 100b22' and the diameter of the second horizontal pore 100b1' of the second pore 100b2' are greater than the diameter of the partitioning pore 100a1' and the diameter of the second vertical non-partitioning pore 100b21'. The diameter of the partition pore 100b21' is smaller than the diameter of the non-partition pore 100a2'. The partition pore group reduces the acid stratification phenomenon. It is best that the volume of the partition pore 100a1' is 0, that is, the average pore diameter of the partition pore 100a1' is 0, that is, the interior of the partition pore 100a1' is completely filled with hydrophobic material 102, and the volume of the second vertical partition pore 100b21' is 0, that is, the average pore diameter of the second vertical partition pore 100b21' is 0, that is, the interior of the second vertical partition pore 100b21' is completely filled with hydrophobic material 102, which can better avoid the acid stratification phenomenon. In this way, the second horizontal pore 100b1' of the second pore 100b' and the second vertical non-partitioning pore 100b22' can reduce the corrosion of the vertical ribs of the grid while retaining a part of the oxygen recombination ability, and also ensure the flow of the acid in the Y direction. The second vertical partitioning pore 100b21' and the partitioning pore 100a1' of the first pore 100a' form a partitioning layer pore group, which can reduce the acid stratification. The non-partitioning pore 100a2' of the first pore 100a' has a strong oxygen recombination ability. The partitioning pore 100a1' of the first pore 100a' and the second vertical partitioning pore 100b21' form a partitioning layer pore group, which can reduce the acid stratification.
