Various factors such as high temperatures, overcharging and external impacts can lead to the collapse of the battery's internal structure. Structural failure of the battery may result in internal short circuits, which in turn can cause rapid temperature increases and potentially lead to thermal runaway, even resulting in fires and explosions .
Some common internal battery faults are overcharge, overdischarge, internal and external short circuit, overheating, accelerated degradation, and thermal runaway. These battery faults lead to potentially hazardous consequences, such as an increase in temperature and pressure, which could increase the risk of combustion and explosion .
Structural failure of the battery may result in internal short circuits, which in turn can cause rapid temperature increases and potentially lead to thermal runaway, even resulting in fires and explosions . Previous studies have extensively investigated the triggering conditions and characteristics of thermal runaway in lithium-ion batteries.
This increases the discharge rate of the battery, which can become a real problem for deep cycle batteries. It is usually difficult to detect and failure to do so will lead to the premature replacement of a battery. In most cases, an internal short is irreversible as it is oftentimes caused by a manufacturing problem.
The range of external pressure and internal deformation during different stages of battery life cycle is clarified. The review facilitates a generalized procedure to determine the …
