Lead-acid battery grid with half-ribsarranged inpositive and reverse staggered mode

Abstract

The invention discloses a lead-acid battery grid with half-ribsarranged in apositive and reverse staggered mode. The lead-acid battery grid with the half-ribsarranged in the positive and reverse staggered mode comprises a battery tab, transverse borders, vertical borders, short transverse ribs, vertical ribs, positive transverse ribs, and reverse transverse ribs; the short transverse ribs are interposed between adjacent positive transverse ribs and reverse transverse ribs, the inner side of the vertical border provided with the battery tab is transversely connected to one ends of the short transverse ribs, and 4 to 6 ribs are connected to connecting positions of the vertical border and are symmetrical with respect to the battery tab; and cross sections of the positive transverse ribs and the reverse transverse ribs are both triangular, the vertex angles of the positive transverse ribs are upward, the vertex angles of the reverse transverse ribs are downward, and the positive transverseribs and the reverse transverse ribs are arranged inside a rectangular formed by the vertical borders and the transverse borders in an alternative and staggered mode. According to the lead-acid battery grid with the half-ribsarranged in the positive and reverse staggered mode, on one hand, total cross section area of transverse ribs on the position of the battery tab is increased by adding extrashort transverse ribs so as to decrease current density of relevant transverse ribs on the position of the battery tab, and thus the corrosion rate on the position of the battery tab is significantlydecreased; on the other hand, the structure of the transverse ribs is improved, lead paste reserving space is greatly enlarged, the technical effect is beneficial to improving charge acceptance of a matching lead-acid battery and prolonging the cycle life.

Description

technical field [0001] The invention belongs to the technical field of electrochemical power supply manufacturing. Specifically, the invention relates to a lead-acid storage battery grid, in particular to a lead-acid storage battery grid with half-ribs arranged in dislocation in front and back. Background technique [0002] Lead-acid battery is a power product with obvious technical characteristics. For a long time, lead-acid battery has occupied an absolute dominant position in the power supply equipment market. We all know that the main failure mode of lead-acid batteries is grid corrosion. If the corrosion resistance of the grid is improved in terms of structure or material, the cycle life of lead-acid batteries can be improved. The grids in the prior art are grid-like, and are composed of vertical ribs and transverse ribs interlaced. In order to reduce the current density of the grid, the number of transverse ribs should be increased as far as possible to increase the s...

AI Technical Summary

Problems solved by technology

However, due to structural limitations in lead-acid batteries, the grid cannot increase the number of transverse ribs arbitrarily. The reason is that sufficient space must be reserved between the ribs of the grid to facilitate the storage of the configured lead paste.

Otherwise, due to the lack of built-in lead paste, the resulting plate cannot achieve the expected effect of the electrochemical reaction, and also cannot achieve the purpose of improving the cycle life of the lead-acid battery.
