2. Common Causes of 18650 Lithium Battery Explosions
There are several common causes of 18650 lithium battery explosions, including:
Thermal Runaway
- Causing Uncontrolled Temperature Increase: Thermal runaway is a phenomenon in which the battery’s internal temperature increases uncontrollably, leading to a chain reaction that can cause the battery to explode.
Overcharging and Overdischarging
- Causing Damage to the Battery Cells: Overcharging and overdischarging the battery can cause damage to the battery cells, leading to overheating, fire, or explosion.
Physical Damage
- Causing Internal Shorts or Other Issues: Physical damage to the battery, such as punctures, cracks, or impacts, can cause internal shorts or other issues that can lead to overheating, fire, or explosion.
Manufacturing Defects
- Causing Internal Shorts or Other Issues: Manufacturing defects, such as poor quality control during the production process, can cause internal shorts or other issues that can lead to overheating, fire, or explosion.
3. Preventive Measures for 18650 Lithium Battery Explosions
There are several preventive measures for 18650 lithium battery explosions, including:
Use of Advanced Battery Management Systems (BMS)
- Monitoring and Controlling Battery Parameters: Advanced BMS can monitor and control the battery’s voltage, current, and temperature in real-time, and take corrective action to prevent overcharging, overdischarging, or overheating.
Proper Charging and Discharging Practices
- Avoiding Extreme Conditions: Proper charging and discharging practices, such as avoiding extreme temperatures or conditions that can cause overheating, can help to prevent thermal runaway and other issues that can lead to explosions.
Regular Inspection and Maintenance
- Identifying Potential Safety Hazards: Regular inspection and maintenance of the battery, such as checking for signs of damage or wear, can help to identify potential safety hazards early and prevent them from becoming significant problems.
