This paper reviews the current development and potential problems of Li-ion batteries, particularly focusing on the failure mechanism and its possible solutions of Li-ion batteries. It has been a general consensus that Li-ion batteries will continue to dominate the battery market in the foreseen future as a convenient electric power source.
On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly. Catastrophic failures often result in venting of the electrolyte, fire, or explosion.
Catastrophic failures often result in venting of the electrolyte, fire, or explosion. This is usually due to an overstress condition where the battery is abused or operated outside of its recommended voltage, current, or temperature limits , , .
This capacity fade phenomenon is the result of various degradation mechanisms within the battery, such as chemical side reactions or loss of conductivity , . On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly.
Overcharge is also a very common electrical abuse form when the battery management system is out of order. The failure mechanism of overcharge attracted considerable attention , , , . As lithium is irreversibly removed from the cathode, the structure of the cathode is changed.
This enables a physics-of-failure (PoF) approach to battery life prediction that takes into account life cycle conditions, multiple failure mechanisms, and their effects on battery health and safety. This paper presents an FMMEA of battery failure and describes how this process enables improved battery failure mitigation control strategies. 1.
