The electrolyte is regarded as the blood of the lithium ion battery, and the pore space of the separator and electrodes is infilled with the liquid electrolyte. During the charge (discharge) process, the lithium ions deintercalate from the cathode (anode), and transferred to the anode (cathode) through the electrolyte. In other words, the
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
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.
The electrolyte can contribute to side reactions with the electrodes that reduce the available capacity of the battery and lead to wearout failure. While the electrolyte most commonly used in lithium-ion batteries has beneficial properties for ion transport, it is highly flammable and unstable outside of a narrow voltage and temperature window.
The FMMEA's most important contribution is the identification and organization of failure mechanisms and the models that can predict the onset of degradation or failure. As a result of the development of the lithium-ion battery FMMEA in this paper, improvements in battery failure mitigation can be developed and implemented.
