This article introduces the causes of swelling in polymer lithium battery packs and provides repair tips.
1. Introduction to the Causes of Swelling in Polymer Lithium Battery Packs
Swelling in polymer lithium battery packs occurs when the battery cells expand due to internal pressure buildup. The global polymer lithium battery pack market is expected to grow significantly in the coming years, driven by increasing demand for efficient energy storage solutions and the growing popularity of electric vehicles and renewable energy systems. However, the issue of swelling in polymer lithium battery packs remains a significant concern for users and manufacturers.
Effects of Swelling
- Safety Hazards: Swelling can pose significant safety hazards, such as the risk of overheating, fire, or explosion.
- Performance Degradation: Swelling can also cause a decrease in the battery pack’s performance, such as reduced energy density or power density.
Data Insight: According to a 2025 Polymer Lithium Battery Pack Market Report, the global polymer lithium battery pack market is expected to grow at a CAGR of 12.5% from 2025 to 2030, driven by increasing demand for efficient energy storage solutions and the growing popularity of electric vehicles and renewable energy systems.
2. Common Causes of Swelling in Polymer Lithium Battery Packs
There are several common causes of swelling in polymer lithium battery packs, including:
Overcharging
- Excessive Voltage: Overcharging the battery pack can cause the battery cells to expand due to excessive voltage.
Overdischarging
- Excessive Current: Overdischarging the battery pack can cause the battery cells to expand due to excessive current.
Exposure to Extreme Temperatures
- Thermal Expansion: Exposure to extreme temperatures, such as high heat or cold, can cause the battery cells to expand due to thermal expansion.
Manufacturing Defects
- Poor Quality Control: Manufacturing defects, such as poor quality control during the production process, can cause the battery cells to expand due to internal pressure buildup.
3. Repair Tips for Swelling in Polymer Lithium Battery Packs
There are several repair tips for swelling in polymer lithium battery packs, including:
Proper Charging and Discharging
- Follow Manufacturer’s Recommendations: Follow the manufacturer’s recommendations for charging and discharging the battery pack to avoid overcharging or overdischarging.
Use of Protective Cases
- Physical Protection: Use protective cases to store and transport the battery pack to prevent physical damage.
Regular Inspection and Maintenance
- Physical Inspection: Regularly inspect the battery pack for signs of swelling or other damage.
- Cleaning: Regularly clean the battery pack to remove any dirt or debris that may accumulate on its surface.
Replacement of Swollen Cells
- Professional Replacement: Replace any swollen cells in the battery pack with new cells to prevent further swelling and ensure optimal performance.
