Abstract :
Commercial Li-ion cells were characterized with AC impedance spectroscopy and constant current discharge capacity measurements. Two models were developed from the data. These two models predict the cell´s AC impedance spectra and voltage discharge curve, respectively. The models are useful for determining the effect of parameters such as temperature, maximum charge voltage, and discharge current on the performance of the cell
