How Does Overcharging Lead to Battery Explosions?

Overcharging leads to battery explosions through a series of interconnected steps. First, batteries contain electrolyte, which is a liquid or gel that helps conduct electricity. When a battery charges, the chemical reactions create energy and generate gas as a byproduct. Next, overcharging occurs when the battery receives more charge than it can safely handle. This excess charge causes the electrolyte to heat up and produce more gas than normal.

As the charging continues, pressure builds up inside the battery. Batteries are designed to contain a specific amount of gas and liquid. When the pressure exceeds safe limits, the battery can swell and potentially rupture. If rupture occurs, the internal components may short-circuit. This short-circuit generates heat, which can ignite the gases inside and lead to an explosion.

In summary, overcharging causes excessive gas production, increases internal pressure, and can result in battery rupture and explosion. Each step in this process highlights the importance of following manufacturer guidelines for charging to prevent dangerous outcomes.
