Battery Aging and Failure Mechanisms

Influence of Aging on the Failing Behavior of Automotive NMC Lithium-Ion Batteries

• Lithium-ion batteries (LIBs) are subject to aging processes that can contribute to safety-critical failures
• Statistics show that many EV accidents do not occur until after about one year of operation, which is why the failure behavior of aged cells is particularly relevant.
• The influence of different aging paths on the failure and degassing behavior of large automotive-grade LIBs is demonstrated
• Aged cells exhibit significantly less explosive failure behavior than fresh cells, with one exception: battery failure due to fresh Li-plating
