The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
Long-term durability is a major obstacle limiting the widespread use of lithium-ion batteries in heavy-duty applications and others demanding extended lifetime. As one of the root causes of the degradation of battery performance, the electrode failure mechanisms are still unknown.
In the mass production of cylindrical lithium-ion batteries, end-of-line testing is generally limited to capacity and open circuit voltage tests, which help in electrical screening but do not address the safety of the battery.
The failure modes with higher risk are prioritized and strategies like engineering controls, design modifications, process improvements and enhanced quality control measures are implemented to minimize the occurrence or impact of the failure mode . Cylindrical lithium-ion batteries are complex systems with multi-step manufacturing processes.
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.
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.
