Experimental analysis of LFP lithium cells aging

Aging of batteries is one the most significant aspects to be considered, when engaged in stationary or mobile applications. With reference to a project currently in progress, based on an accurate analysis of fast charging operations, some experimental tests have been carried out on an LFP lithium cell, to analyze its aging over time, when subjected to different solicitations of power requested. Additionally, several aging indicators have been defined, measured and analyzed, to be compared each other and to verify their correlation with the cell aging levels. Preliminary results show that part of these indicators can correctly be used as good cell aging predictors, giving a unique aging trend.
