What causes lithium batteries to expand?
If there’s a flaw in a lithium-ion battery, the charging process will create a small amount of gas in the battery’s sealed chamber. Over time, that gas will build up and cause the battery to expand.
Why do old lithium batteries swell?
Lithium-ion batteries use a chemical reaction to generate power. As the battery ages, this chemical reaction no longer completes perfectly, which can result in the creation of gas (called outgassing), leading to a swollen battery.
What causes battery to expand?
Swollen batteries are the result of two things: energy density and heat. The swelling is the result of too much current coursing, in a noncontrolled fashion, inside a cell of the battery, which causes a build-up of heat and gas.
What do you do with a bloated lithium battery?
How to Remove and Dispose of a Swollen Battery
- Do Not Charge or Use the Device.
- Remove the Battery.
- Dispose of the Battery at an Authorized Recycling Center.
- Keep Your Batteries Cool.
- Use a Quality Charger.
- Replace Old Batteries.
- Don’t Leave It Plugged In.
Can a swollen battery Be Fixed?
Can you fix it? There is no way a swollen battery can be repaired. The only options are to replace the battery, or to replace the entire device.
Do all lithium batteries swell?
Lithium-ion cells can swell due to many reasons, but somehow the issue of deep discharge swelling and the related hazards with charging such a battery seem to be widely underestimated.
How do you deflate a swollen battery?
– The battery percentage drops sharply. To fix a battery that is swollen or inflamed, it is very simple, you just have to remove it from the phone and then put it in an airtight bag, and then place it on the refrigerator in the freezer or refrigerator for 30 minutes.
Can you put a swollen battery in the freezer?
Do not put the battery in the freezer. Freezing may cause already-damaged metal components to contract and could cause a short, leading to fire. Freezing is outside the engineered temperature range even for an undamaged battery, leave the battery at ambient temperature.
Can swollen battery be repaired?
Thanks for A2A. Unfortunately you cannot fix the swollen battery by cooling it down, it’s nothing to do with the temperature when it’s already bloated. The only suggested way is to remove the battery. The reason why your phone battery got cooked might be overcharging.
How do you shrink a swollen battery?
First aid for battery bulges There is no point waiting for the battery to “shrink”. The ever growing pressure can cause damage to the entire device. Leave the battery in the device only if it is stuck. Never try to “solve” the swelling yourself by pricking a hole in it or with any other creative stunt.
How do you flatten a swollen battery?
The first thing you should do with a swollen battery is to run your phone’s charge down (keeping an eye on the device the whole time), then put it in a cool, dry place while you evaluate your next options.
Can you Unswell a battery?
Unfortunately you cannot fix the swollen battery by cooling it down, it’s nothing to do with the temperature when it’s already bloated. The only suggested way is to remove the battery. The reason why your phone battery got cooked might be overcharging.
What causes a lithium battery to expand and become swollen?
It can be a puzzling sight, so what exactly is going on inside that lithium battery that makes it expand and become swollen? Lithium batteries swell when there’s a buildup of gas inside the battery. This gas buildup can be caused by extreme temperatures, a damaged or low-quality battery, or issues with overcharging or discharging energy.
What causes a battery to swell when charging?
This forms lithium oxide on the anode and cathode (depending whether you are charging or discharging). But what you also end up with is excess oxygen that doesn’t adhere to the anode or cathode. This excess oxygen is part of what causes a battery swell. And oxygen likes to burn.
Is it safe to remove a swollen lithium-ion battery?
a swollen lithium-ion battery may catch fire or explode. PROCEED WITH EXTREME CAUTION AND AT YOUR OWN RISK WHEN REMOVING A SWOLLEN BATTERY FROM AN ELECTRONIC DEVICE. IF YOU HAVE ANY DOUBTS ABOUT YOUR ABILITY TO DO SO SAFELY, POWER DOWN AND ISOLATE THE DEVICE, AND CONSULT A PROFESSIONAL REPAIR TECHNICIAN IMMEDIATELY.
What are the risks of a swollen battery?
The risk of battery swelling, while low, is inherent with Lithium-ion Polymer cell technology, which is widely used across the tech industry (not unique to Dell or PCs). The issue is industry-wide affecting all notebook computer companies. A swollen battery may impact the performance of the notebook and in some cases damage the product enclosure.
