Why does phone battery bulge?

According to li-ion battery research lab employee, phone battery bulge causes due to buildup of gas inside. The gases are produced due to electro-chemical oxidation of the electrolyte. Such oxidation occurs usually due to overcharging of the battery due to a faulty battery, or faulty charging electronics in the phone or battery charger. So these are the 2 reasons for why the battery will bulge. So using the branded charger and switching off the battery after completing 100% of its its charge can avoid this battery bulging. We all have a habit of putting up your phone charging during your sleep and the phone keeps charging for the entire night till you wake up which is the very main reason for decreasing your battery life.

The bulge that you find in the middle of the battery is a combination of hydrogen gas and breakdown products of some of the other components in the battery. You should stop using such a battery immediately and dispose it off. li-ion batteries are dangerous and a large buildup of gas will cause them to burst and possibly catch fire, spreading toxic fumes.
