Have you ever come across a situation when the lithium-ion battery in your phone, laptop, or any other device gets swollen or puffed up? If yes, then this might be a dangerous situation for that that must be handled carefully. Lithium-ion batteries have a plethora of advantages which involve long battery life, high energy density, etc. Along with these advantages, there are quite a few disadvantages as well, amongst which one of the most common and hazardous disadvantages is that lithium is a lot more reactive substance than other substances which are found in other type of batteries. Due to this disadvantage, the cells of the lithium-ion battery can produce gas when overheated, and the pressure caused by that gas can cause the swelling up of lithium-ion batteries.

So, if you are facing the issue and looking for a safe solution for it, then we are here to help you out! In this article, we'll let you know everything about "Why Do lithium batteries Swell- Meaning, Fixing And Solution."

Let's start then!

What does it mean when a lithium battery puffed up?

Most of the electronic devices that you use in your daily life, like laptops, tablets, smartphones, etc., have lithium batteries equipped in them. These lithium batteries sometimes swell up due to overheating. This overheating or overcharging of lithium batteries can make them puffed up, which can later prove to be dangerous for you.

Lithium batteries use a chemical reaction to generate the required power. As the battery ages, this chemical reaction does not complete perfectly that can later result in the creation of gas which ultimately leads to a swollen lithium battery. In addition to this, if the internal layers of the battery do not maintain proper separation due to defect or damage, then, in that case, swelling, outgassing, or even fire explosion can occur.

Identifying a swollen lithium battery in your device is essential because it can be risky for you if it is not identified on time. So, always make sure to identify the swollen battery in your device as quickly as possible. However, identifying a swollen battery can be quite challenging because you never know when the battery starts swelling. Still, some signs show that your device's battery is swelling up. If we talk about a laptop, when the battery swells, they expand and push the other parts of the laptop out of the way. Sometimes, a display, track pad, or button will be pushed out of normal alignment. So, these are the signs that show the lithium battery in your device is puffed up.
