What to do with a swollen lithium-ion battery | Smartphone, Laptop, or Tablet
Have you ever noticed that your smartphone, laptop, or tablet feels a bit heavier or thicker than usual? Or that the screen seems to be popping out of the case? If so, you might have a swollen battery. A swollen battery is a battery that has expanded due to internal gas pressure. It is not only an annoying problem that affects the performance and appearance of your device, but also a serious safety hazard that can cause fire, explosion, or toxic fumes.

There are many factors that can cause a battery to swell, such as aging, overcharging, or overheating. These factors can damage the delicate structure of the battery and trigger a chemical reaction that produces gas inside the battery. The gas builds up and pushes against the battery casing, causing it to deform and bulge. This can also damage the device and the charger, creating a vicious cycle of more heat and more gas.

In this article, we will explain what to do with a swollen battery, how to identify it, how to safely remove it, how to dispose of it, and how to take care of your battery to prevent or reduce swelling. By following these steps, you can protect yourself, your device, and the environment from the dangers of a swollen battery.

What happens when a battery gets swollen?

A lithium-ion battery is composed of two electrodes (anode and cathode) separated by a liquid electrolyte and a thin membrane. The electrolyte allows the flow of lithium ions between the electrodes, which creates an electric current. When the battery is charged, the lithium ions move from the cathode to the anode, and when the battery is discharged, they move back to the cathode.

However, when the battery is damaged, overcharged, or overheated, the electrolyte can react with the electrodes and produce unwanted byproducts, such as lithium metal, carbon dioxide, or hydrogen. These byproducts form gas bubbles inside the battery, which increase the internal pressure and cause the battery to swell. The swelling can also damage the membrane, which can lead to a short circuit or a thermal runaway, a chain reaction of heat and gas that can result in fire, explosion, or toxic fumes.

A swollen battery can also deform the device and the charger, making them more prone to overheating or malfunctioning. This can create a vicious cycle of more heat and more gas, which can worsen the situation and increase the risk of a catastrophic failure. Therefore, it is important to identify and remove a swollen battery as soon as possible, and to dispose of it properly.
