What is the biggest risk associated with batteries in aviation?

The primary risk associated with batteries in aviation is thermal runaway. This phenomenon occurs when a battery becomes excessively heated, leading to a rapid increase in temperature and pressure. As the battery’s internal temperature rises, it can trigger a self-reinforcing cycle, causing more heat and potentially a catastrophic failure. In aviation, where safety is paramount, thermal runaway can result in fires or explosions, endangering both the aircraft and its occupants.

Understanding thermal runaway is crucial for pilots and technicians, as prevention strategies include proper battery management, temperature monitoring, and ensuring that batteries are not subjected to conditions that could lead to overheating. This highlights the importance of rigorous maintenance and checks to mitigate such risks.

Other risks, while still significant, do not pose the same level of threat as thermal runaway in the context of aviation safety. Therefore, the focus on thermal runaway reflects its potential impact on aviation operations.
