Complete process flow of lead-acid batteries

Introduction to the formation process

Plate formation and battery formation are two different methods of battery manufacturing, which can be selected according to specific conditions. Polar plate formation is generally relatively easy to control, the cost is high, and environmental pollution requires special treatment. It is difficult to control the quality of battery formation. Generally, the quality of the produced plate is relatively high, but the cost is relatively low. A brief description of the formation of sealed valve-regulated lead-acid batteries is as follows:

The first step

Put the qualified raw plates into the battery tank and seal according to the process requirements;

The second step

Pour a certain concentration of dilute sulfuric acid into the battery according to the specified amount;

The third step

After placing, turn on the DC power according to the specified size , After general formation, it is necessary to carry out discharge inspection and assembly, and then put it in storage and prepare for delivery.

The main control parameters of battery formation: tank acid content; tank acid density; tank acid temperature; charging capacity and time, etc.

Introduction to the assembly process

Battery assembly has a big difference between car batteries and sealed valve-regulated lead-acid batteries. The requirements for sealed valve-regulated lead-acid batteries are tight. AGM separators are generally used for assembly, while PE, PVC or rubber separators are generally used for car batteries. The assembly process is briefly described as follows:

The first step

Put the qualified electrode plates into the welding tool according to the process requirements;

The second step

p>

Put the cast-welded or hand-welded pole groups into a clean battery slot;

Step 3

The car battery needs to be welded through the wall and heat sealed. Yes, but if the sealed valve-regulated lead-acid battery adopts ABS battery slot, it needs to be bonded with a special adhesive.

The main control parameters of battery assembly: busbar welding quality and materials; sealing performance, positive and negative polarity, etc.

Use and maintenance

Lead-acid batteries are irreplaceable in the secondary chemical power supply due to their simple manufacturing process, rich source of raw materials, and moderate prices. The role, especially the appearance of valve-controlled batteries, has made traditional storage batteries full of vitality. The service life of the battery is closely related to the manufacturing, and it also has a great influence on the method of use. The correct use of the method is of great benefit to prolong the life of the battery.

For traditional open-type batteries, the following aspects must be paid attention to daily:

1·The amount, density and charging degree of electrolyte should be paid attention to, especially the closely related charging The system is particularly concerned. If the charging capacity is large, the battery will lose more water, which will easily cause the active material of the plate to fall off, causing the bottom short circuit to make the internal temperature of the battery higher and shorten the life. If the charging capacity is small, it will easily cause the battery to lose power. In the case of a long-term loss of electricity, the battery can cause irreversible sulfation of the plates. The performance is that the voltage rises quickly during the charging process and is completed in a short time, and the voltage drops rapidly during discharge.

2·The purity of the electrolyte is generally filled with special electrolyte or replenisher for batteries, and it is strictly forbidden to replace it with ordinary sulfuric acid and tap water.

3·Daily use the surface to keep clean, the exhaust port is unblocked.

4·When it is not in use, it should be fully charged and recharged once every three months.

For sealed valve-regulated lead-acid batteries, the following aspects must be paid attention to daily:

1·Pay attention to the range of charging voltage when floating charge, the voltage is generally controlled at 2.15±0.1V/single The voltage is generally controlled at 2.35±0.1V/single grid during recycling. If required by the instructions, please operate according to the instructions.

2·Pay attention to the ambient temperature, generally not more than 30 degrees Celsius. When the temperature changes greatly, the voltage regulation should be strengthened.

3·The products of different manufacturers cannot be mixed, and the old and new products of the same manufacturer cannot be mixed.

4·Seal valve-regulated lead-acid battery is best not to open the lid to replenish the electrolyte and replace the safety valve.
