Horizontal battery structure and production process thereof

Abstract

The invention discloses a horizontal battery structure and a production process thereof, the horizontal battery structure comprises two storage battery outer wall plates, a forming shell and a storage battery plate group, the storage battery plate group is arranged between the two storage battery outer wall plates, the forming shell fixedly connected with the storage battery outer wall plates is formed between the two storage battery outer wall plates through a forming process, and the storage battery outer wall plates are connected with the forming shell. Compared with the prior art, the integrated storage battery shell for clamping the storage battery plate group is reliable in sealing, simple and convenient to operate, high in efficiency and low in cost.

Description

【Technical field】 [0001] The invention relates to the technical field of storage batteries, in particular to the technical field of a horizontal battery structure and its production process. 【Background technique】 [0002] figure 1 It is a traditional battery. Its structure and process are as follows: battery tank 1, negative plate 2, separator 3, positive plate 4, battery cover 5, battery positive terminal 6, negative bus bar 7, positive terminal 8, liquid injection hole 9, safety valve 10, And positive busbar, cross bridge and so on. The assembly process is to first stack positive plates, negative plates, and separators according to the specified number to form pole groups, then put the pole groups into molds, weld them into pole groups, and then put the pole groups into the bottom of the battery. The tank (called the tank-entry process), and finally the battery cover is installed, and the battery assembly is completed through processes such as liquid injection and chem...

Problems solved by technology

[0006] The main disadvantage is that each single cell of the battery consists of several positive plates, several negative plates and several separators. To achieve sealing, all positive plates, negative plates, and separators must be sealed by welding, especially The connection between the two single cells needs to be absolutely reliable

However, the ultrasonic welding method is used for sealing operation, and the sealing reliability is low. If the ultrasonic equipment fluctuates or the basic dimensional error is too large or there are pollutants on the surface, the sealing will not be strict. After the battery is manufactured, there will be high self-discharge and bipolar plates. Severe corrosion occurs at the connection between the positive and negative electrodes, which leads to short service life of the battery, low capacity retention rate, and faults such as charging and heating, which greatly reduces the implementation effect of the invention patent

At the same time, the liquid injection hole of the battery is placed above the plane of the pole plate. Since the electrolyte is first added to the surface of the upper plate when injecting liquid, it is not easy for the electrolyte to penetrate into the pole group, and the consistency of the liquid injection is poor.

[0007] In addition, in order to solve the isolation problem between horizontal battery cells, technicians use several rubber seals to install between the single cells as isolation, which can basically achieve reliable sealing. However, the material and production cost of such rubber seals are high. , the installation efficiency is low, which increases the finished product and weakens the competitiveness of the product
