What to Do with an Overheating Lithium Battery?
When a lithium-ion battery overheats, it poses significant safety risks, including the potential for fire or explosion. If you encounter an overheating lithium battery, it’s important to take immediate action to cool it down and prevent further issues. Understanding the causes and appropriate responses can help ensure safety.
What causes lithium-ion batteries to overheat?
Lithium-ion batteries can overheat due to several factors:
- Overcharging: Charging beyond the recommended voltage can generate excessive heat.
- Internal Short Circuits: Manufacturing defects or physical damage can lead to short circuits, causing rapid heating.
- High Ambient Temperatures: Exposure to high temperatures, such as leaving batteries in hot vehicles, can increase the risk of overheating.
- Excessive Discharge: Using the battery beyond its rated capacity can also lead to overheating.
Causes of Overheating Chart
| Cause | Description |
|---|---|
| Overcharging | Excessive voltage during charging |
| Internal Short Circuits | Damage or defects causing rapid heating |
| High Ambient Temperatures | Exposure to extreme heat |
| Excessive Discharge | Drawing too much power from the battery |
How can you cool down an overheating lithium battery?
If a lithium battery is overheating, follow these steps:
- Move Away from Flammable Materials: Immediately place the battery at least 15 feet away from any combustible items.
- Do Not Touch: Avoid touching the battery directly; use a long-handled tool if necessary.
- Cool Down with Water: If safe, immerse the battery in a container of water for at least 24 hours. This helps dissipate heat effectively.
- Monitor for Signs of Fire: Keep an eye on the battery for any signs of smoke or flames.
