According to the data, the worst model year was 2011 with a 7.5% failure rate (aside from recalls). In the next few years, it was 1.6-4.4%, which indicates that several percent of EV users were affected by a battery failure.
The consequences of these mechanical failures on battery performance, lifetime and safety vary depending on the specific type of failure. However, the complex nature of mechanical degradation in batteries often involves interrelated processes, in which different failure mechanisms interact and evolve.
In the next few years, it was 1.6-4.4%, which indicates that several percent of EV users were affected by a battery failure. As we can see in the chart, starting in 2016, there was a step change in the battery replacements due to failures, excluding recalls. It was as high as 0.5% starting in 2016, but in most cases, it was from 0.1% to 0.3%.
In conclusion, addressing mechanical failures in LIBs is crucial for making significant advancements in battery performance, lifetime, and safety, as well as for advancing next-generation battery technologies.
Overall, it is identified that the main failure factor in LIBs during high discharge rate is attributed to loss of active material (LAM), while loss of active Li-ions (LLI) serves as a minor factor closely associated with formation of devitalized lithium compounds within active materials. 2. Experimental section 2.1. Battery samples
Extensive research has demonstrated that mechanical failures play a crucial role in determining battery performance, lifespan, and safety [1, 2]. LIBs are intricate and dynamic systems with continuously evolving composition, structure, and properties .
Questions and Answers Relating to Lithium-Ion Battery Safety Issues
The key is whether we feel comfortable with the probability of failure. Let us make a simple calculation. Assume that the self-induced failure rate at the vehicle level is calculated by p = 1 − (1 − P) m × n, where P is the failure rate for m electric vehicles, each of which has a battery pack containing n cells. 1 Taking the Tesla Model S as an example, n = …
