Lithium-ion batteries are popular in modern-day applications, but many users have experienced lithium-ion battery failures. The focus of this article is to explain the failures that plague lithium-ion batteries. Millions of people depend on lithium-ion batteries. Lithium-ion is found in mobile phones, laptops, hybrid cars, and electric vehicles.
This work comprehensively investigates the failure mechanism of cell sudden death under different degradation paths and its impact on cell performances. Multi-angle characterization analysis shows that lithium plating is the primary failure mechanism of battery sudden death under different degradation paths.
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.
In an experimental study Kassem et al. showed a complex relationship between degradation and efficiency . Authors experimented with two different types of lithium-ion batteries; NMC and LFP batteries where it has been shown that NMC and LFP cells age differently from one another.
Lithium-ion batteries can experience overvoltage and undervoltage effects. As noted in Figure 1, the operating voltage and temperature of the battery must be maintained at the point marked with the green box. If it is not, the cells can be damaged. Figure 1.

State of Charge In lithium-ion batteries, battery degradation due to SOC is the result of keeping the battery at a certain charge level for lengthy periods of time, either high or low. This causes the general health of battery to gradually deteriorate.
Lithium-Ion battery cell failures can originate from voltage, temperature, non-uniformity effects, and many others. Voltage effects can occur either due to overvoltage or undervoltage effects. Overvoltage effects happen …
