1. Battery Capacity Issues
   
   

   One of the most common problems faced by automotive quality specialists, such as SQAs (Supplier Quality Assurance) and SQE (Supplier Quality Engineering) is decreased battery capacity. As batteries age, the amount of energy they can store decreases. In practice, this translates into a shorter vehicle range. To address this challenge, it is important to establish rigorous standards for capacity monitoring over time. Advanced testing technology, such as electrochemical impedance spectroscopy, can be a powerful ally in assessing and preventing early degradation.

2. Safety Issues and Fire Hazards
    
   The safety of lithium batteries is a priority that cannot go unnoticed. Short circuits, overloading, and overheating can lead to dangerous fire hazards. Quality professionals should be aware of these potential issues and focus on prevention and mitigation. Incorporating advanced battery management systems and temperature and voltage sensors can help detect and control risky situations.

3. Material Quality Issues
    
   The presence of impurities or defective materials can lead to malfunction and safety risks. An effective approach to this problem is the implementation of strict quality requirements for material selection, along with continuous monitoring throughout the supply chain.

4. Shelf Life Issues
    
   Consumers expect a reasonable lifespan from lithium batteries, and degradation issues can lead to significant concerns. The investment in research and development to extend the life of batteries is substantial. This could involve optimizing battery chemistry, designing more efficient battery management systems, and implementing up-to-date monitoring techniques.

5. Recycling and Sustainability Issues
    
   Proper disposal of end-of-life batteries is a matter of constant concern, which is currently under development to reduce environmental impact. For quality professionals, this means approaching quality from a broader perspective that includes not only the initial performance of the battery, but also its environmental impact throughout its lifecycle.

Simply put, quality issues in lithium batteries are exciting challenges that require innovative solutions and a dynamic approach. The constant pursuit of excellence in lithium battery quality is essential to ensure a future of sustainable and safe mobility.
