The answer is yes. The battery is responsible for storing electric energy. However, when overcharged or discharged, the diaphragm in the inferior battery cell may be broken down, causing the cell to short circuit, causing high temperature and high pressure and explosion. Therefore, mobile phone batteries are most likely to explode during charging.
As we know, most mobile phone batteries are lithium batteries. Lithium is the smallest and most active metal on the chemical periodic table. It is small and has high capacity density. The chemical properties of lithium are too active. When lithium metal is exposed to the air, it will react violently with oxygen and explode. In order to improve safety and voltage, scientists have invented materials such as graphite and lithium cobaltate (as well as lithium iron phosphate, lithium manganate and ternary materials) to store lithium.
However, even so, it only improves the security, not absolute security. Mobile phones still have the risk of explosion.
