Here's how it works:
* Positive Electrode (Anode): This is made of lead dioxide (PbO2).
* Negative Electrode (Cathode): This is made of pure lead (Pb).
Electrolyte: The electrolyte is a solution of sulfuric acid (H2SO4).
How it Works:
When the battery discharges, lead dioxide reacts with sulfuric acid to form lead sulfate (PbSO4) and water. Simultaneously, the lead on the negative electrode also reacts with sulfuric acid to form lead sulfate. This chemical reaction creates an electrical current.
Charging the Battery:
When you recharge the battery, the process reverses. An external electrical current forces the lead sulfate back into lead dioxide and lead, and the water molecules are broken down to release hydrogen and oxygen.
Important Note: Lead is a toxic heavy metal, so it's crucial to handle lead-acid batteries responsibly and recycle them properly.
