Why do mobile phone batteries swell?

You might notice the size of your mobile phone's battery, but what is happening to it? Why is it swelling each day? Your mobile phone consists of a lithium-ion battery, and it uses a chemical reaction to give your mobile power so you can operate it. Once the chemical reaction gets affected for any reason, your battery will start swelling because the battery will start creating gas. 

When the battery starts making gas, this process is known as out-gassing, which makes your battery start swelling. If you keep putting your phone on charge and using it, the battery will keep getting swelled to a point when it will finally burst. 

Aging is the reason.

Every electronic device comes with an expiry date and batteries too. If its been years that you have been using the same lithium-ion battery in your cellphone, then this might be why the battery has started swelling. There is no other reason for this situation other than aging. 

Overcharging your Cellphone

We have mentioned out-gassing above, and the battery starts producing that gas if it gets overcharged other than the aging reason. When you leave your cellphone on charge for hours, and once the battery is charged completely, after that point, the electrodes and electrolytes present in the battery will start making heat and gas.

Therefore, checking your cell phone when you put it on charging is important. If you keep leaving your cell phone on charge for several hours, then the gas might cause a crack in your cellphone's battery. The battery can explore when overly recharged. 

Will it be safe to use a swollen phone battery? 

If your cellphone battery is swelling or getting swelled, that means the battery is producing gas and causing out-gassing. This situation doesn't sound ideal, and you shouldn't use that swollen phone battery. If you keep using and charging it, there will be significant consequences.
