, From Sally Zhuang, 10 min reading time
In the world of portable electronic devices, lithium batteries are becoming increasingly popular due to their high energy density and long lifespan. However, one concern that often arises among users is: Do lithium batteries leak? The truth is: Yes, they can.
In this article, we discuss the possibility of lithium battery leakage and provide you with important information on how to prevent such incidents.
Can lithium batteries leak?
With lithium-ion batteries, there's a very small chance of spillage, but as with any battery, there's a small risk. It's important to minimize this risk through precautionary measures.
It is important to ensure that the voltage supplied by the battery is suitable for your device or that your device can handle the voltage provided.
One advantage of lithium batteries is their ability to maintain power over extended periods. Even if your device's batteries remain plugged in for extended periods, they will continue to function without adverse effects. This is not the case with alkaline batteries, which release gas under high pressure and humidity.
As long as you take appropriate measures to prevent leakage, using lithium batteries is safe.
The combination of portability and reliability has led to the rapid adoption of lithium batteries. Under normal conditions, they are leak-proof. It is recommended to store them with a charge level between 50% and 60%. and 70% and store in a dry and cool place.
In what situation do lithium batteries leak?
Lithium-ion batteries have a minimal risk of leakage compared to other battery types. However, in rare cases, lithium batteries can leak if they are physically damaged or exposed to extreme temperatures. If the battery casing is punctured, the chemicals inside the battery can leak out, potentially causing damage. Below are some details.
- Overload
Lithium batteries can leak if overcharged because the electrolyte inside decomposes and gases are released. This can cause the battery to expand and, in extreme cases, burst. To prevent this, modern lithium batteries, such as Power Queen LiFePO4 lithium batteries, but with overcharge protection circuits BMS (Battery Management System). These circuits help regulate the charging process and minimize the risk of overcharging and resulting leakage.
- Damage
Lithium-ion batteries can also leak if they are physically damaged, such as being dropped or punctured. When a battery is damaged, the electrolyte can leak and react with other components, causing leakage. To address this problem, reputable lithium battery manufacturers often conduct rigorous drop tests to evaluate their products' durability and resistance to damage. By ensuring you purchase batteries from reliable sources like Power Queen, you reduce the likelihood of leakage due to damage.
- Defects in production
Although rare, leaking batteries can be caused by manufacturing defects, particularly defects in the battery seals. Poor seal design can cause electrolyte to leak, resulting in leaks.To mitigate this risk, it is important to purchase new batteries from trusted stores and reputable lithium cell battery manufacturers.
- temperature
Lithium batteries can leak if exposed to excessively high temperatures outside their safe range. The elevated temperature can damage the electrolyte and cause it to leak from the battery. To prevent this type of leak, it is important to Store lithium batteries in a cool and dry environment and follow the manufacturer's instructions. By keeping batteries within the recommended temperature range, you can help prevent leakage due to temperature-related damage.

Immediate treatment if a lithium battery leaks
Check the battery case for visible damage such as dents or punctures that could cause leaks. Look for improper battery installation or welding slag in the battery case.
Remove the cover plate and check the safety valve for signs of acid leaks. Make sure the valve is open and observe if electrolyte is flowing into the battery.
If the previous steps appear normal, test the seal by pressurizing it and submerging it in water. Look for air bubbles, as these indicate a faulty seal. If there are no bubbles, the seal is likely intact.
Check for electrolyte during charging. If detected, carefully remove it.
Once the source of the leak is identified, carefully clean the affected area with a knife. Then apply a strong battery-safe adhesive to seal the leak.
Remember that battery quality is directly related to leakage incidents. When purchasing batteries, prioritize authentic and high-quality options from trusted suppliers.
How to prevent a lithium battery from leaking
Here are a few additional tips to prevent lithium battery leakage:
-
Do not expose batteries to extreme temperatures
Extreme temperatures can cause lithium batteries to leak or deteriorate. Avoid storing or using batteries in excessively hot or cold environments, as this can damage the electrolyte within the battery.
-
Avoid using damaged batteries
Using damaged batteries increases the risk of leakage. If you notice swelling, leakage, or unusual behavior from your lithium battery, discontinue use immediately and dispose of it safely.

What is the least likely thing that a lithium battery will leak?
Among leading lithium-ion battery chemistries, lithium iron phosphate (LiFePO4 or LFP) technologies have demonstrated increased intrinsic resistance to leakage issues compared to alternatives such as lithium cobalt oxide or lithium nickel manganese cobalt oxide. A stable phosphate cathode and an inert electrolyte system contribute to reduced chemical reactivity, which could otherwise lead to unwanted releases.
Although much safer overall, no battery technology can be completely flawless or immune to all failure modes. However, LFP batteries are far less susceptible to thermal runaway due to the delayed oxidation properties of their chemistry. This lower risk of uncontrolled overheating mitigates a major cause of chemical fractures and leakage in less stable lithium-ion cells.
Additional benefits such as extended temperature operating ranges and longer cycle life further reduce the likelihood of leakage. By minimizing stress on the containment mechanisms, LFP batteries can better protect enclosed electrolytes from environmental influences over broader usage profiles than many competitors.
Of course, careful handling always remains important. However, the inherent properties of LFP technologies provide an excellent foundation for improved protection against unwanted emissions throughout the battery's lifetime. For applications requiring the highest levels of safety, their phosphate compositions are a compelling option.
Is the leakage of a LiFePO4 lithium battery toxic?
No, LiFePO4 (lithium iron phosphate) lithium batteries do not contain any toxic substances that would leak if the battery were damaged. Unlike other lithium battery chemistries, LiFePO4 batteries are considered significantly safer and more stable. They have a lower risk of leakage or thermal runaway. LiFePO4 batteries are made of non-toxic materials and are therefore environmentally friendly and safe to use.
