Free QuoteThis article provides its reader with information on the design of secondary lithium-ion batteries and some of the reasons why a lithium-ion battery may fail in an unsafe manner.
Free QuoteHowever, failures can cause lithium battery packs to malfunction. The type of problem will be based on the construction of the battery pack, how it is charged, how it is used and handled, and environmental factors.
In these rare instances, the failure was due to metallic microscopic particles that came into contact with parts inside the battery cell. This contact caused a short circuit.
One of the most common failures is the result of the battery pack overheating. Overcharging the battery is one cause to heating issues. The excess charge combines with higher temperatures (such as direct sunlight). The battery pack experiences an increased level of stress. Thermal runaway is another factor that can impact lithium ion batteries.
Using the incorrect charger for the lithium battery pack can also cause a range of problems. Most battery pack chargers for lithium-ion batteries are designed to prevent overcharging. However, using the wrong charger can cause overcharging or over voltage of the lithium battery pack as well as swelling.
Consequently, the electrolyte may cause propagating circuit board failures, leading to external heating of the cell and forcing the cell into thermal runaway. Safety issues can occur when the battery cell or the circuit is mechanically stressed or damaged.
Battery faults represent a broad spectrum of issues that can occur in a battery system, significantly impacting its performance, safety, and longevity. These anomalies, often complex and multifaceted, range from minor deviations in battery operation to severe incidents, leading to catastrophic damage and failure.
