Data for: Analysis and modeling of calendar aging of a commercial LiFePO4/graphite cell

This data is from a comprehensive calendar aging study on a lithium-ion battery with a test duration of 29 months:

This aging study was realized with a widely used commercial LiFePO4/graphite cell from Sony/Murata, which promises both long calendar and cycle lifetime, which is especially required for stationary battery applications. The development of the cells’ capacity, as well as the resistances, are shown in a static calendar aging study for 17 test points, each with 3 cells, having constant storage conditions of temperature and state of charge. Based on the measurement data, a semi-empirical aging model is presented for the capacity loss and resistance increase, consisting of only 5 parameters which are valid for all storage conditions.
Due to limited space, only a selection of the 17 test points of the calendar aging study are evaluated in the paper. However, this dataset represents the data for evaluation of all 17 test points. The data is grouped into four files representing the different issues of evaluation as given in the section 'Experimental' in the paper.
