Abstract
This work aims to update current lithium ion battery lifetime models in order to provides more accurate predictions on batteries for use in electric/hybrid cars. This requires new physics-based models and an understanding of mechanical degradation factors of NMC particles and the properties of each component over the life span. Thus, this work will measure the mechanical properties of individual particles using nanoindentation to develop a better understanding of the fundamental material physics behind battery degradation and to standardizes material preparation techniques and testing procedures.
