How Do Lithium Batteries Typically Fail and What Causes Their Death?
Lithium batteries typically fail due to factors such as overheating, overcharging, and internal short circuits, leading to reduced capacity and eventual death.
Overheating occurs when lithium batteries operate at elevated temperatures. This can happen from excessive usage or faulty charging systems. A study by Nagaoka et al. (2018) indicated that temperatures above 60°C (140°F) can significantly shorten battery lifespan. Elevated temperatures can cause thermal runaway, where an increase in temperature leads to further reactions within the battery, potentially leading to fires or explosions.
Overcharging is another common cause of lithium battery failure. This happens when a battery continues to receive a charge beyond its maximum voltage limit. According to the U.S. Department of Energy (2020), overcharging can generate excess heat and lead to the breakdown of the electrolyte, which diminishes the battery’s ability to hold a charge. This phenomenon can result in cellular damage and reduce the battery’s overall capacity.
Internal short circuits can also lead to battery death. Short circuits happen when the separator between positive and negative electrodes fails, allowing them to touch. Research by Thomas et al. (2019) showed that a physical deformity or manufacturing defects can cause internal shorts, resulting in rapid energy release and thermal events.
Degradation from cycling, or repeated charge and discharge cycles, contributes to a decrease in capacity. A study by Zhang et al. (2021) found that lithium-ion batteries lose about 20% of their capacity after 500 cycles, primarily due to structural changes in the electrodes and electrolyte decomposition.
Finally, age plays a role in lithium battery death. Aging leads to increased resistance within the battery, which reduces efficiency and capacity over time. The California Lithium-Ion Battery Recycling Initiative (2021) illustrated that batteries can lose up to 30% of their capacity after just two to three years of use, regardless of charging patterns.
In summary, lithium batteries fail due to overheating, overcharging, internal short circuits, capacity degradation from cycling, and aging, each contributing to reduced performance and eventual death.
