Batteries: 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.

2 Lead-Acid Batteries The open circuit voltage of a battery is more complicated than that of a fuel cell. This is because it must depend on the state of charge of the battery, which determines how much of each reactant and product is present, and hence their activities. One example of a battery is the lead-acid battery, used in cars.
