Problems solved by technology

[0006] However, during the internal formation process of the storage battery, it is necessary to fill the assembled battery with electrolyte solution and charge it. When the battery is damaged, it is easy to cause internal short circuit and seriously affect the internal formation of the battery, which will eventually lead to the failure of the battery production.

Embodiment 1

[0040] like Figure 7 and Figure 8 As shown, the bipolar lead-acid battery includes a casing 1 with a battery cavity 11 a inside, several single cells 2 arranged in the battery cavity 11 a and a safety valve 3 connected outside the casing 1 . Wherein, the several single cells 2 in the battery chamber 11a are independent, and each single cell 2 has an inner cavity 21 for electrolyte injection, and the inner cavities 21 of the several single cells 2 are also independent of each other, and the housing 1 is located above the battery cavity 11a and has several mutually independent gas distribution chambers 12a, the number of gas distribution chambers 12a is the same as that of the single batteries 2, and the number of gas distribution chambers 12a is the same as the inner cavity 21 of several single batteries 2. A corresponding communication, there is also a common pressure chamber 14a located above the gas distribution chamber 12a in the housing 1, and several gas distribution c...

Embodiment 2

[0049] The technical solution of this embodiment is roughly the same as that of Embodiment 1, the difference is:

[0050] The sealing rubber ring 4 can adopt a split structure, and be connected as a whole by means such as gluing; Figure 10 As shown, the middle part of the anti-climbing wall diaphragm 5 has several transverse ribs 51, which are used to increase the strength of the anti-climbing wall diaphragm 5 itself, making it difficult to deform and ensuring its isolation between the two bipolar substrates 25. effect.

Embodiment 3

[0052] The technical solution of this embodiment is roughly the same as that of Embodiment 1, the difference is that:

[0053] like Figure 11 As shown, the middle part of the anti-climbing wall diaphragm 5 has several ribs 51 staggered horizontally and vertically, which are used to increase the strength of the anti-climbing wall diaphragm 5 itself, so that it is not easily deformed, and ensures that the opposite electrode substrate 26 is compatible with the bipolar The isolation function between the substrates 25 and between two bipolar substrates 25 .

Abstract

The invention provides a bipolar lead-acid storage battery, belongs to the technical field of storage batteries and solves the problems that existing storage batteries have short service life and areproduced unsuccessfully. The bipolar lead-acid storage battery comprises a casing with a battery cavity inside and multiple cells arranged in the battery cavity, each cell comprises an inner cavity allowing injection of an electrolyte, the inner cavities of the cells are independent of one another, multiple air distributing chambers communicated with the inner cavities of the cells in a one-to-onecorrespondence are arranged in the casing and located above the battery cavity, a co-pressure cavity is also formed in the casing, and all the air distributing chambers are communicated with the co-pressure cavity through vent holes. The bipolar lead-acid storage battery has the advantages that the bipolar lead-acid storage battery can be produced successfully and used normally.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and relates to a bipolar lead-acid accumulator, in particular to a bipolar lead-acid accumulator with common pressure in gas distribution chambers. Background technique [0002] The structure of a bipolar lead-acid battery includes a positive terminal plate, several bipolar plates, a negative terminal plate, a separator, an electrolyte, a battery tank, and a battery cover. Among them, the bipolar plate is formed by coating the positive electrode paste and the negative electrode paste on both sides of the bipolar substrate respectively. Through the design of the bipolar plate, the utilization rate of the lead paste is improved and the specific energy is high. [0003] For example, the applicant designed a bipolar lead-acid battery and applied for a Chinese patent (its application number is: 201710179695.8; its publication number is: CN106876804A), the bipolar lead-acid battery includes a shel...
