Lead acid battery reduction and oxidation
The lead acid battery has two electrodes, one made of metallic lead, and the other made of lead dioxide $ce{PbO2}$. Remember that, whatever the operation (charge or discharge), the anode is always the electrode where oxidation occurs. Let''s consider first the discharge process.
Contact UsBatteries: Electricity though chemical reactions
Batteries can explode through misuse or malfunction. By attempting to overcharge a rechargeable battery or charging it at an excessive rate, gases can build up in the battery and potentially cause a rupture. A short circuit can also lead to an explosion. A battery placed in a fire can also lead to an explosion as steam builds up inside the battery.
