In this presentation, we will share Exponent’s approach to failure analysis of lithium-ion batteries. Following our outside-in methodology from the exterior electronics to interior cell chemistry, we will identify critical features observed in certain failures and essential analytical techniques used to pinpoint root cause. We will also address the challenges related to failure analysis of batteries with larger form factors and higher energy densities, and we will show how we have adapted our methodology to the characteristics of these specific batteries.
