Manufacturing Defects

• Impurities: Metal particles may enter the cell during manufacturing, causing short circuits and overheating.
• Thin separators: Poorly designed separators can lead to internal short circuits, increasing the risk of fire.

2. Design Flaws

• Compact designs: High-capacity cells crammed into smaller spaces may compromise the battery’s safety features.
• Cooling systems: Lack of proper cooling or venting systems can lead to overheating and thermal runaway.

3. Improper Use

• External heat: Exposing batteries to heat sources or puncturing them can cause short circuits.
• Improper charging: Overcharging or using unauthorized chargers can damage the battery over time.

4. Charger Issues

• Poorly insulated chargers: These may cause short circuits or generate heat, leading to battery failures.

5. Low-Quality Components

• Substandard electronics: Cheap components, like poorly designed battery management systems (BMS), increase the likelihood of battery failures and fires.
