How to make a valve-regulated lead-acid battery?
The first step in forming a sealed valve-regulated lead-acid battery is to put the qualified unformed plates into the battery tank for sealing according to the process requirements; the second is to pour a certain concentration of dilute sulfuric acid into the battery according to the specified amount.
How does acid react with a battery?
The acid solution reacts with the plates to identify the quality of the battery. Connect the specified number of batteries in series, charge, and discharge according to the process, activate the battery, and make the positive and negative active materials form a certain amount of lead dioxide and spongy lead.
What is a lead-acid battery made of?
A lead-acid battery has electrodes mainly made of lead and lead oxide, and the electrolyte is a sulfuric acid solution. When a lead-acid battery is discharged, the positive plate is mainly lead dioxide, and the negative plate is lead. The lead sulfate is the main component of the positive and negative plates when charging.
What is a lead sulfate battery?
The lead sulfate is the main component of the positive and negative plates when charging. The nominal voltage of a single-cell lead-acid battery is 2V, which can be discharged to 1.5V and charged up to 2.4V. In applications, 6 single-cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery.
What happens when a lead-acid battery is discharged?
When a lead-acid battery is discharged, the positive plate is mainly lead dioxide, and the negative plate is lead. The lead sulfate is the main component of the positive and negative plates when charging. The nominal voltage of a single-cell lead-acid battery is 2V, which can be discharged to 1.5V and charged up to 2.4V.
How to make battery plate active material?
(1) Lead powder and cast alloy grid: The lead powder is the primary raw material for making battery plate active material. The qualified lead bars are cut into lead pellets filled in the ball mill, and through the rotating drum, the lead balls fall under the action of their gravity, collide with each other, and rub into powder.
