Lead-acid battery production process

The production process of lead-acid battery can be divided into the following main links:
1. pole plate production: pole plate is the core component of lead-acid battery, and its production process includes:
a. Ingredients: According to a certain formula, lead, antimony, calcium and other raw materials are mixed.
b. Smelting: the mixed raw materials are melted into liquid.
c. Pouring: Pour the melted lead liquid into the mould, cool and solidify it to become the pole plate.
d. Surface Treatment: Clean and coat the surface of the pole plate to improve the performance of the battery.
2. Battery Assembly: Combine the parts such as pole plates, electrolyte and separator into a complete battery. This process mainly includes the following steps:
a. Weighing the plates: according to certain weight requirements, the plates are graded.
b. Assembling: Putting the pole plates, separators, electrolyte and other parts into the battery shell.
c. Welding: connect the plates to form the positive and negative poles of the battery.
d. Formation treatment: Formation treatment of the newly assembled battery to improve the performance of the battery.
e. Testing: Performance testing of the finished battery to ensure that the quality is up to standard.
3. Formation treatment: Formation treatment for newly produced batteries to improve the performance of batteries. The formation process includes:
a. Charging: Charge the newly assembled batteries to make them reach a certain voltage.
b. Discharge: Discharge the charged battery so that the lead sulphate in the electrolyte is converted into active substance.
c. Cycle: Repeat the charging and discharging process until the battery performance meets the requirements.
4. Finished product testing and packaging: the performance of the finished battery is tested to ensure that the quality is up to standard. Qualified batteries for packaging and factory inspection.
In short, the production process of lead-acid battery includes the production of pole plate, battery assembly, chemical processing and finished product testing and so on. In this process, strict process flow and quality control is crucial to ensure the production of excellent performance, safe and reliable batteries.
