Takeaways of Lithium-ion Battery Failure. Lithium-Ion battery cell failures can originate from voltage, temperature, non-uniformity effects, and many others.
Lithium-ion batteries are popular energy storage devices for a wide variety of applications. As batteries have transitioned from being used in portable electronics to being used in longer lifetime and more safety-critical applications, such as electric vehicles (EVs) and aircraft, the cost of failure has become more significant both in terms of liability as well as the cost of
