Similarly, when you use a battery, the process of discharging causes the ions to move back to their original positions. This movement also generates heat due to resistance within the battery. Lithium-ion batteries are particularly susceptible to heat generation during charging and discharging.
Why does a battery get hot if overcharged?
The more excessive the overcharging, the more heat is generated. In addition to chemical reactions, the internal resistance of the battery also plays a role in overheating. As the battery is overcharged, the internal resistance increases, which causes energy to be converted into heat. This further contributes to the battery becoming hot.
