Pole plate of lead-acid battery

Abstract

The invention discloses a pole plate of a lead-acid battery. The pole plate of the lead-acid battery comprises a plurality of vertical ribs which are arranged longitudinally and a plurality of horizontal ribs which are arranged transversely, wherein the vertical ribs and the horizontal ribs are in a cross distribution to form a rectangular mesh which has a longitudinal length greater than a transverse length. Under the condition of ensuring invariable size of the mesh in a pole plate grid structure, the pole plate of the lead-acid battery regulates the structural distribution of the vertical ribs and the transverse ribs, and increases the number of the vertical ribs and decreases the number of the transverse ribs to form a structure with more vertical ribs and less transverse ribs, so that the transmission of current is more rational and smooth, the electric conductivity of the pole plate is improved; the cost is equivalent to the original cost; even phenomena, such as ruptures, severe corrosion and the like, of individual vertical ribs do not influence the capacity of the whole battery; the performance is improved; and the service life is prolonged.

Description

【Technical field】 [0001] The invention relates to a lead-acid battery, in particular to the improvement of the lead-acid battery pole plate structure. 【Background technique】 [0002] Lead-acid batteries are secondary batteries that use lead and acid as active materials. The active material of the positive electrode is lead dioxide PbO 2 , the active material of the negative electrode is spongy lead Pb, the electrolyte dilute sulfuric acid H 2 SO 4 Both participate in the positive and negative electrochemical reactions. The flow reaction principle of the battery is as follows: [0003] [0004] During the charging and discharging process of the battery, the current transmission is mainly transmitted upward through the vertical ribs of the plate, and the horizontal ribs are mainly involved in supporting the active material, and basically do not participate in the current transmission. [0005] The current plate uses such as figure 1 The structure shown has many horizo...

AI Technical Summary

Problems solved by technology

[0005] The current plate uses such as figure 1 The structure shown has many horizontal ribs and few vertical ribs, which makes the current transfer unreasonable and smooth, and the performance is poor

[0006] In addition, in the processing structure of all the plates in a single battery with the traditional plate structure, as long as one vertical bar breaks or is severely corroded, the capacity of the entire battery will be greatly affected due to the small number of vertical bars. Affected, almost scrapped
