As difficult as the name suggests, lead acid batteries are actually the most commonly used batteries for any application that needs recharging like starting the engine of a car. They have low energy density and require higher maintenance, but are long-lasting and cheaper in cost compared to other types of batteries.
The battery consists of two electrodes; the negative one is made of porous lead, while the positive electrode is made up of lead oxide. The electrolytic solution is made up of dilute sulphuric acid.
History
The question of why Gaston Plantes suddenly thought of making a "Swiss roll" remains unanswered, but his principle is still followed in the manufacturing of the present-day lead acid battery by battery acid manufacturers. There are a few steps, rather secrets, followed in the manufacturing of lead acid batteries.
Manufacturing lead battery plates
As much as the lead plates cost, it is essential to buy good battery plates for the electrodes of the battery. The manufacturer must be prepared to spend as much money as required for the making of a good battery.
Adding lead paste
The space between the electrodes is filled with lead paste or lead acid battery water or dilute sulphuric acid as a substitute for an electrolytic solution.
Differently charged electrodes
There are two types of electrodes separated by an electrolytic solution: positive and negative. The positive electrodes are made up of lead dioxide, while the negative electrodes are made up of porous lead.
Inserting non-conductive separators
The positive and negative electrodes are made sure to be separated by a material that does not conduct electricity. Failing to do so would completely destroy the principle of the lead-acid battery. The separator is usually made of paper, glass, or plastic which are non-conductors of electricity.
Charging and Discharging
Finally, charging starts taking place which may take several days. The charge that is formed could, either be dry or, it could be wet.
- In case of dry formation, the electrodes are dried and connected to the terminals of the battery.
- While, in the wet form of charge, the electrolytic solution needs to be changed from time to time.
- After the initial charging, they are also discharged for some time.
- This process is repeated a number of times to assume the best working condition, which is checked with the help of measuring instruments.
- If all goes right, the battery is packed into a sealed cotton case and dispatched to different places.
