The lead-acid storage battery belongs to a reversible direct-current power supply, can convert chemical energy into electric energy, and can also convert the electric energy into chemical energy. The lead-acid storage battery mainly comprises electrolyte, a tank cover and a polar group, wherein the electrolyte of the lead-acid storage battery is sulfuric acid solution, the polar group mainly comprises a positive plate, a negative plate and a separator, and the separator mainly stores the electrolyte and serves as a gas channel for oxygen recombination to prevent active substances from falling off and prevent short circuit between the positive electrode and the negative electrode.

Disclosure of Invention
Aiming at the problems of longer current conduction path and larger internal pressure drop of the grid in the prior art, the utility model provides the lead storage battery grid, which has short current conduction path and small internal resistance.
The utility model provides a lead accumulator grid, includes the frame that comprises last frame rib, lower frame rib and two vertical frame ribs, and horizontal rib and the vertical rib of crisscross formation network structure in the frame to and set up the utmost point ear on last frame rib, vertical rib draws in to the slope of the position that utmost point ear is located, and their extension line intersects in a point, and this intersection is located the utmost point ear directly over, and the interval of upper and lower frame rib and the ratio of this intersection and the interval of lower frame rib are golden section proportion. I.e., the ratio of the spacing of the upper and lower rim ribs to the spacing of the intersection point and the lower rim rib is about 0.618. The end points of all the longitudinal ribs are straight line segments from the intersection points, the distance between the straight line segments is shortest, the resistance is proportional to the length of the ribs, the distance is shortest, and the internal resistance is smallest. If the longitudinal ribs are prolonged and finally do not intersect at one point, the current conducting paths finally become a dispersed state, the conducting paths are dispersed to lead the conducting current values to be dispersed, and the current in the dispersed state is unfavorable for the instant discharging of the storage battery. When the longitudinal ribs are prolonged and finally intersected at one point, the current value of the point is the sum of the current of the whole polar plate, so that the instant current value is increased, and the high-current discharge performance is improved. When the storage battery is discharged, the discharge performance and the service life of the storage battery are important indexes. If the depth of discharge per unit time is too large, the lifetime is reduced. And when the discharge capacity of the storage battery is 60% -65% of the whole storage battery, the storage battery is charged so as to ensure the service life.
The included angle between two adjacent longitudinal ribs is 3 degrees.
The height of the electrode lug is H, the distance between the outer edge of the electrode lug and the middle point of the upper frame rib is L, and the intersection point of the electrode lug and the upper frame rib is an elliptic focus taking 2L as a long axis and 2H as a short axis.

The longitudinal ribs between the lower frame rib and the adjacent transverse ribs are connected end to end in a zigzag mode. The bottom of the accumulator is easy to be damaged in the process of manufacturing the polar plate and when the accumulator is vibrated, so the design is more beneficial to the effective maintenance of active substances.
The width of the longitudinal ribs gradually increases from the lower frame rib to the upper frame rib. Because the utilization rate of active substances at the upper part of the polar plate is higher, thickening of the longitudinal ribs at the upper part can reduce internal resistance, and is favorable for instant current collection.
The upper frame rib and the vertical frame rib close to the tab are thicker than the lower frame rib and the other vertical frame rib. The utilization rate of active substances of the upper frame rib and the vertical frame rib close to the tab is high, so that thickening can reduce internal resistance and is beneficial to instant current collection.
The widths of the upper frame rib and the vertical frame rib close to the tab are 3mm, and the widths of the lower frame rib and the other vertical frame rib are 2mm.
One end of each transverse rib is a tapered section with gradually changed width. One side close to the conical section is a grid casting port, and the side close to the casting port of the transverse rib is thickened to form the conical section, so that the quantity of lead flowing in per unit time in the casting process is increased, thereby being beneficial to casting and forming and being beneficial to keeping active substances in the vertical direction of the polar plate.

Detailed Description
Example 1
As shown in fig. 1, a lead storage battery grid comprises a frame composed of an upper frame rib 1, a lower frame rib 2 and two vertical frame ribs, transverse ribs 5 and longitudinal ribs 6 which are crisscross to form a net structure in the frame, and a tab 7 arranged on the upper frame rib 1, wherein the two vertical frame ribs are respectively a vertical frame rib 3 far away from the tab 7 and a vertical frame rib 4 close to the tab.
In order to enhance the connection effect of the tab 7 and the upper frame rib 1, deformation and cracks are not easily caused by heat generated during the working of the storage battery, and the width of the base part of the tab 7 is gradually increased. The bottom of the accumulator is easy to be damaged in the process of manufacturing the polar plate and when the accumulator is vibrated, so that the longitudinal ribs 8 between the lower frame rib 2 and the adjacent transverse ribs 5 are in a zigzag shape in order to be more beneficial to the effective retention of active substances. In order to increase the utilization rate of active substances at the upper part of the polar plate, the width of the longitudinal ribs 6 is gradually increased from the lower frame rib 2 to the upper frame rib 1, so that instant current collection is facilitated.
The utilization rate of active substances of the upper frame rib 1 and the vertical frame rib 4 close to the pole lug is high, the upper frame rib 1 and the vertical frame rib 4 close to the pole lug 7 are designed to be thicker than the lower frame rib 2 and the other vertical frame rib 3, internal resistance can be reduced by thickening, and instant current collection is facilitated. In one embodiment, the widths of the upper frame rib 1 and the vertical frame rib 4 adjacent to the tab 7 are 3mm, and the widths of the lower frame rib 2 and the other vertical frame rib 3 are 2mm.
The transverse ribs 5 have one end with a tapered section 9 of gradually changing width. The side close to the conical section 9 is a grid casting port, and the side close to the casting port of the transverse rib 5 is thickened to form the conical section 9, so that the amount of lead liquid flowing in unit time in the casting process is increased, thereby being beneficial to casting and forming and also beneficial to keeping active substances in the vertical direction of the polar plate.
As shown in fig. 2, the longitudinal ribs 6 are inclined toward the direction in which the tab 7 is located, and their extension lines intersect at a point O which is located directly above the tab 7. The angle between two adjacent longitudinal ribs 6 is 3 degrees. The end points of all the longitudinal ribs 6 to the intersection point O are straight line segments, the distance between the straight line segments is shortest, the resistance is proportional to the length of the ribs, the distance is shortest, and the internal resistance is smallest. If the longitudinal ribs 6 are not intersected at one point, the current conducting paths are dispersed, so that the conducting current values are dispersed due to the dispersion of the conducting paths, and the instant discharge of the storage battery is not facilitated by the current in the dispersed state. When the longitudinal ribs 6 are lengthened and finally intersected at a point, the current value of the point is the sum of the current of the whole polar plate, so that the instant current value is increased, and the high-current discharge performance is improved.
The spacing L1 between the upper rim rib 1 and the lower rim rib 2, the spacing L2 between the intersection point O and the lower rim rib 2, and the ratio of L1 to L2 are the golden section ratio, which is about 0.618. When the storage battery is discharged, the discharging performance and the service life of the storage battery are important indexes, if the discharging depth in unit time is too large, the service life can be shortened, and when the discharging capacity of the storage battery is 60% -65% of the whole storage battery, the storage battery is charged to ensure the service life.
As shown in fig. 3, the height of the tab 7 is H, the distance between the outer edge of the tab 7 and the midpoint of the upper rim rib 1 is L, and the intersection point of the tab 7 and the upper rim rib 1 is the focal point of an ellipse with 2L as the major axis and 2H as the minor axis. All the current of the polar plates is finally conducted through the polar lugs, and after the positive polar plates and the negative polar plates are assembled into a polar group, the two current collecting points are just positioned at the focal point of the ellipse. When the storage battery is discharged, current flows from the negative electrode to the positive electrode, and when the storage battery is charged, current flows from the positive electrode to the negative electrode. When the current collection point is positioned at the focal point of the ellipse, the electric field curve at the focal point is the most dense, and the electric field intensity is the strongest at the place where the electric field curve is dense. The electric field lines of one focus of the ellipse are totally reflected to the other focus through the ellipse surface, which means that the current generated by the anode and the cathode is 100% utilized no matter charging or discharging, so the instant current value generated by the grid designed by the ellipse focus is obviously improved.

After the two grids are assembled into a 6-EVF-200 storage battery, the high-current discharge conditions at different temperatures are detected, the measured data are shown in table 1, and the time of the high-current discharge is longer than that of a storage battery prepared by using the grids in example 1 in comparison group.
