Why Lithium Batteries Leak

Lithium batteries power many devices in your home, but they can leak if you do not use or store them properly. Understanding why lithium batteries leak helps you lower the risk of leakage and keep your family safe.

Перезарядка

When you overcharge a lithium-ion battery, the voltage rises above safe limits. This causes the electrolyte inside to break down and release gases. The pressure inside the battery increases, which can make the battery swell or burst. Перезарядка not only shortens battery life but also raises the risk of leakage and fire. Most modern lithium-ion batteries have built-in safety features to prevent overcharging, but you should still watch charging times and use the right charger. Never leave batteries charging overnight or unattended.

Физический ущерб

Physical damage is a major reason why lithium batteries leak. Dropping, puncturing, or crushing a battery can crack the casing or break the seals. This lets the electrolyte escape, creating leaky batteries. Damaged batteries may also short-circuit, which increases the risk of leakage and fire. Always handle lithium-ion batteries with care. If you see swelling, dents, or other signs of damage, stop using the battery right away.

Poor Storage

Storing lithium batteries in hot, humid, or poorly ventilated places increases the risk of leakage. High temperatures speed up chemical reactions inside the battery, which can cause swelling, gas buildup, and leaks. Moisture can corrode metal parts and damage the battery’s internal structure. You should always store lithium-ion batteries in cool, dry places with stable temperatures. Avoid leaving batteries in cars or near heat sources.

• High temperatures increase the risk of thermal runaway, swelling, and venting.
• Excessive moisture causes corrosion and short circuits.
• Poor ventilation leads to gas buildup and leaks.

Design or Quality Issues

Battery quality matters. Poor manufacturing, low-quality materials, or counterfeit products can make lithium batteries leak. Defective batteries may have weak seals, missing safety features, or poor voltage control. These problems raise the risk of leakage, fire, and even explosions. Always buy lithium-ion batteries from trusted brands and check for safety certifications. Certified batteries go through strict testing to lower the risk of leakage.

Примечание: Thermal runaway is a dangerous chain reaction in lithium-ion batteries. When the battery gets too hot, it can heat up even more, causing the electrolyte to break down and release flammable gases. This can make the battery vent, leak, or even explode. Always follow safety tips to lower this risk.
