Why does lithium-ion battery explode?

So, talking about the mechanism of a battery, it consists of two electrodes, one is Cathode (positive charge) and Anode (negative charge) and in between, them consist of an electrolyte, so when electrons move in between anode and cathode then we are able to use power from a battery to use mobile.

As our requirements have been increased and almost every individual needs a long-lasting and quick-charge battery so most of our phone’s batteries are lithium-ion batteries which fulfill our requirements which is a high energy density battery and also lithium-ion batteries are less stable that’s why sometimes it can’t handle so much energy and your phone smells like burning.

Local charger or USB cable

On being cheap and easily available many of us buy local chargers or USB cables which could lead to your phone smells like burning or even more dangerous issue.

As they don’t have safety guards like how much power to give to your mobile and sometimes, they emit more than enough power which can lead to your phone smells like burning.


Usage of mobile while charging

As our mobile is charging and if we are playing games or watching movies while charging it would drain as well as charge the battery at the same time which could lead to the rise in temperature of your device, and it can also lead to your phone smells like burning.


Switchboard or Extension board

Sometimes the real issue is not in your mobile phone, charger, or cable, it’s on your switchboard or extension board.

Maybe the switch on your board is defective and by that, its power circulating mechanism can get distorted and that’s the reason why your phone smells like burning.


Back cover

Using a tight back cover can compress the heat and also lead to phone smells like burning

Placing the smartphone in hot places

Sometimes we place our smartphones in hot places like in the kitchen, over the oven or stove, etc, which could lead to an increase in temperature and can lead to phone smells like burning.



As most of us think that overcharging is safe but sometimes it can be very dangerous, as we all know our smartphones are called smart so if you overcharge your battery then at the mobile full charge it auto cuts the charge and thus prevent your mobile by exploding, and all it is done by a chip which is inbuilt in your mobile phone for only this reason, but what if your overcharging deduction chip gets damaged or malfunction, then it could be a serious issue and could lead to your phone smells like burning, also overcharging your smartphone with local charger and USB cable can lead to your phone smells like burning.
