When lithium batteries are exposed to overheating or defects, they can undergo combustion, which involves a rapid and potentially violent reaction that can result in fire. This is due to the chemical composition of lithium batteries; when they are subjected to high temperatures, internal pressure can build up, leading to thermal runaway. In a thermal runaway scenario, the temperature continues to increase uncontrollably, causing the electrolyte within the battery to ignite. This is especially critical in applications like drones, where battery integrity is paramount for both safety and operational performance.

Combustion poses serious hazards, including the risk of fire spreading to other components or the surrounding environment. Proper handling, storage, and monitoring of lithium batteries are essential to mitigate this risk and ensure safe usage, particularly in scenarios where external conditions could lead to overheating or damage.
