Monomer horizontal battery and manufacturing method thereof

Abstract

The invention discloses a monomer horizontal battery and a manufacturing method thereof. The monomer horizontal battery comprises positive terminal polar plates, diaphragms and negative terminal polar plates which are horizontally arranged; seen from bottom to top, the positive terminal polar plates 1 and the negative terminal polar plates 2 are alternately and horizontally placed; the diaphragms 9 are arranged between the up and down adjacent positive terminal polar plates 1 and negative terminal polar plates 2; one edge with end line of each positive terminal polar plate 1 is located on a first position; one edge with end line of each negative terminal polar plate 2 is located on a second position; the first position and the second position are adjacent or opposite to each other. The monomer horizontal battery and the manufacturing method thereof provided by the invention can save materials, can solve the problem of influence on the service life of the deep discharging of the battery caused by inconsistent positive and negative lead plaster ratio of horizontal bipolar battery polar plates, can guarantee the realization of excellent sealing of polar groups between the units, can reduce the self-discharging of the horizontal battery, can promote the uniformity of the horizontal battery and prolong the service life of the battery and simultaneously can guarantee that the other excellent performances (such as large current charge-discharge) of the horizontal battery are not influenced.

Description

technical field [0001] The present application relates to the field of storage battery technology, in particular to a single-level battery and a manufacturing method thereof. Background technique [0002] One of the shortcomings of traditional closed lead-acid batteries is: the electrolyte stratification phenomenon caused by the vertical placement of the battery plates inside; the electrolyte stratification phenomenon, that is, the polarization phenomenon of poor electrolyte concentration, This is one of the main causes of reduced battery capacity and shortened life. [0003] Through the improvement of the battery manufacturing process and the structure of the battery itself, a horizontal battery has now appeared. The horizontal battery is named after the battery plates inside it are placed horizontally. Horizontal batteries overcome the problem of electrolyte stratification in traditional batteries due to the horizontal placement of the battery plates. The pole plate of t...

AI Technical Summary

Problems solved by technology

After the acid discharge is completed, high-temperature liquid paraffin needs to be injected. After the paraffin is cooled and solidified in the battery, shrinkage cavities are formed in the cell compartments due to thermal expansion and contraction, so that connection channels for acid liquid and acid gas are generated between the cells, resulting in cell failure. The connection between them forms a micro-battery, which leads to self-discharge and affects the consistency of the battery;

[0007] 3. Internal cell series acid problem: For example, a 12V horizontal battery has 6 internal cells, and the acid gas and acid liquid generated inside will connect to the cells in several cells during charging and discharging, causing reactions in the 6 cells Inconsistent efficiency and inconsistent self-discharge affect the consistency of the battery;

[0008] 4. The cells of the existing horizontal battery are sealed with wax filling, and the interior cannot achieve a good sealing effect. During the storage of the battery, the self-discharge of the six unit compartments in the battery is different due to the difference in the sealing effect of wax filling, and the self-discharge of the unit compartments is different. Larger, it will have a greater impact on the consistency of the battery;

[0009] 5. Horizontal bipolar batteries cannot produce larger capacity batteries due to structural design reasons

In the field of large-capacity applications, multiple groups of batteries need to be connected in parallel, but due to the inconsistent self-discharge of horizontal bipolar batteries, it cannot meet the life requirements of large groups of batteries.
