摘要：

This paper discusses the impact of calendar ageing on the anode and the concentration of lithium ions in the anode structure. It discusses the modeling of the calendar ageing, its implementation in the 3D First Principle Based Degradation Model (3DM) of the battery and the results that were observed as a result of calendar ageing over a period of 4-6 years. The paper also relates these physical degradation phenomena with the impact that they have on the parameters of the Equivalent Circuit Model of the battery. The paper uses the capacity degradation and the increase in the internal resistance of the battery to showcase the impact of calendar ageing on the State of Health of the battery.
