Problems solved by technology

Although these methods can increase the corrosion resistance of the grid, the grid coating process in actual production is complicated, the difficulty and cost of large-scale industrial production are high, and the yield rate of gravity casting of the grid in actual production is low, so it is necessary to purchase continuous punching and rolling The grid production line reduces the price advantage of low-cost lead-acid power batteries compared with lithium-ion batteries

Embodiment Construction

[0016] The present invention will be described in detail below through specific embodiments.

[0017] Such as figure 2 As shown, a new light-weight lead-acid power battery grid is composed of a tab 1, a frame 2, a horizontal rib 3 and a vertical rib 4, and the tab 1 is located on one side edge of the frame 2. The grid body is provided with a number of vertically interwoven vertical ribs 4 and horizontal ribs 3 to form a longitudinal rectangular grid, the spacing of the horizontal ribs 3 is 1.5 to 2.0 times the spacing of the vertical ribs 4, and the number of vertical ribs 4 is the same as that of traditional grids. 2~3 times of that, improve the current converging capacity, make the current transmission distance shorter, and reduce the ohmic voltage drop on the plate.

[0018] The grid body of the novel light-weight lead-acid power battery is rectangular. The grid body is 131-135mm long and 62-65mm wide. mm, reduces the amount of lead used, effectively reduces the weight o...

Abstract

The invention relates to a novel light-weight lead-acid power battery grid; the novel light-weight lead-acid power battery grid is characterized in that the grid is composed of tab 1, a frame 2, transverse ribs 3 and vertical ribs 4, wherein the tab 1 is positioned at the edge of one side of the frame 2; and the vertical ribs 4 and the transverse ribs 3 are vertically interlaced and combined to form a longitudinal rectangular mesh, wherein the distance between the transverse ribs 3 is 1.5-2.0 times of the distance between the vertical ribs 4, and the number of the vertical ribs 4 is 2-3 timesthat of a traditional grid. The grid can be used for preparing a power lead-acid battery, a lead-carbon battery and the like with high rate, high energy density and long cycle life and capability of improving current convergence, so that the current transmission distance is shorter, the ohmic voltage drop on a polar plate is reduced, the grid is safer, and the grid is suitable for popularization and application.

Description

technical field [0001] The invention relates to a component part of a lead-acid storage battery, in particular to a novel light-weight lead-acid power battery grid. Background technique [0002] Lead-acid batteries have experienced nearly 150 years of development, and their power batteries have important commercial value due to their high reliability, low cost, excellent high and low temperature performance, and a recovery rate of more than 98%. Fields (such as electric mopeds, electric motorcycles, etc.) still occupy a major market share. However, the traditional lead-acid power battery monomer (12V20Ah) has short cycle life (80% DOD, ~300 cycles), high monomer weight (~7.2kg), low power and poor high and low temperature performance (Southeast Asia and China The northern cold region), which limits the application development of this low-speed power vehicle with high safety, low cost and great commercial value. [0003] Faced with this challenge, most researchers have devo...
