The Efficiency of Lithium-ion Batteries Comes at an Expense

There's no doubt that the lithium-ion battery is a well-tested and technique-proven option for electronic devices of today for industrial use as well as consumer electronics. From the massive battery of 4680 which will be used in Tesla EVs to the light, slim, and durable battery pack that you can put in your smartphone or wireless headphones They're everywhere.

The lithium-ion battery isn't flawless despite its numerous advantages, i.e., high density and long-lasting. As the battery age and the process for creating power can become faulty and result in a ballooning battery. Additionally, improper management and the use of patterns could be contributing factors to the problem.

What Causes The Battery to Swell?

The situation that comes with an over-saturated battery is similar to an overcrowded playground, where security methods are not in place. Furthermore, the unrestful particles within the layers of the battery react with the exterior air moisture, leading to the body of the battery becoming swollen. In the end, these causes frequently explain the problem.

Natural aging. Electrical equipment can last for a long time as well lithium-ion batteries. As time goes by the chemical reaction in the battery will not be as efficient when the battery is created. Additionally, the internal layers don't remain in a proper segregating condition of them. A typical lithium-ion battery should last for two to three years of use.

A cooling vest has been blocked (happens typically to laptops). If the vent of the cover of the port for filling up with battery is blocked, gas will slowly build up when the charging duration exceeds the recommended time or voltage of charging exceeds the recommended voltage. This will cause pressure inside the battery box and eventually result in a swelling of the battery.

Insufficient charging. This is the most frequently cited reason for the swelling of the battery. When the charging current for the battery is too high or the charging duration is too long, an excessive amount of gas is generated. Additionally, excessive current or an excessive amount of time to charge can also trigger a rapid rise in the temperature of the electrolyte. This can quickly bloat the battery.

A discharge that exhausts. Lithium-ion batteries may be bloated due to the discharge depth or defective BMS (battery management system).

Symptoms of a Swollen Battery

What can you do to identify a bulging battery? The best way to detect a swollen battery is to look at your device's exterior. For instance, if your laptop is beginning to show unnatural "curves" on the keyboard area. Your phone's aluminum frames loosen up and it isn't able to be placed in a uniform manner on the desk.

What should I do about My Swollen Battery?

Is a Swollen Battery Dangerous?

(an old man scratched and scratched an over-swollen battery, which ignited in a cell phone repair station)

Yes, absolutely. It is possible to harm the whole device, as the bulges in batteries generate temperatures. Not to mention that the change in shape can break the shell made of the metal container and trigger a short-circuit or even ignite. Additionally, the harmful outcast that is flammable from batteries made of lithium-ion is a threat to your home keeping, pets as well as human life.

Does it help shrink The Swollen Battery by freezing it?

No. Putting the battery in the refrigerator won't decrease the oxygen content of the battery, nor does it address the root issue of the lithium-ion defect. In the end, freezing out-paces the temperature range that is portrayed within the battery. So the battery will probably fail in the end.

How to Safely Remove a Swollen Battery?

It's always a smart decision to seek out the authorized technical repair station because they're equipped with the full toolset as well as highly trained technicians to address your issue. However, if you do decide to take out a battery that is swollen yourself, follow these steps.

The first step is to turn off your device and don't charge it.


  1. Wear protective measures such as gloves that are isolated and masks with goggles when necessary to shield your hands, eyes, and face from the fire and battery-related chemicals.
  2. Use a pair of dull tongs to remove the battery from its shell.
  3. Find a cool, well-ventilated area, and then prepare the fireproof
    container with soft dry sand. The container should be placed on the floor.
  4. When you're taking the battery off be sure that you shouldn't squeeze it or pull it.
  5. After the battery has been removed and the battery is removed, put it
    back in your container till you can find an appropriate location to get rid of it.

Where to Dispose of a Swollen Battery?

Since a bulging battery can be dangerous if it is not treated properly You should visit the nearest authorized recycling facility. If your area doesn't have one, you can contact the manufacturer of the device and their customer support department to resolve the bulge issue in your battery. Do not throw batteries into regular garbage.

How to Prevent a Swollen Battery?

Be aware of these guidelines when you use your devices. It's important and will help them live longer.

Now You Know

A battery that is swollen can be dangerous and shouldn't be used for longer. Keep in mind potential battery bulges and ensure that we use batteries correctly. No matter if the battery has swollen or not, it is important to eliminate it promptly after it has retired.
