In recent years, the electrification rate of modern machinery and appliances has shown an increasing trend. This trend caused a shift in focus on battery power, especially as a source of storage power. Lithium-ion batteries are used as an excellent source of sustainable power in many complex engineering systems. From high energy density to their lightweight feature, lithium-ion batteries supersede over other battery types. However, these batteries fail in certain aspects of operation which is a major concern in terms of safety and reliability. In this work, we have studied major failure mechanisms of lithium-ion batteries under different operating conditions. Failure mechanisms were then related to physics-based models to understand the degradation process of batteries in actual operations over a period of time. This understanding enriches the health-monitoring-based prognostic analysis of battery management systems.
