This paper deals with the characterization of Lithium batteries discharged by high power pulses. The experiments were conducted with a commercial ultra high power Li-Ion cell (A123 26650M1-A), which was tested by means of an ad - hoc implemented experimental setup under controlled climatic conditions. Performance reduction of the cell, in terms of capacity and efficiency losses, is analyzed and discussed. Furthermore, this paper investigates the degradation effects and aging of the battery with regard to the frequency behavior of the equivalent impedance using the electrochemical impedance spectroscopy technique.

Abstract
This paper deals with the characterization of Lithium batteries discharged by high power pulses. The experiments were conducted with a commercial ultra high power Li-Ion cell (A123 26650M1-A), which was tested by means of an ad - hoc implemented experimental setup under controlled climatic conditions. Performance reduction of the cell, in terms of capacity and efficiency losses, is analyzed and discussed. Furthermore, this paper investigates the degradation effects and aging of the battery with regard to the frequency behavior of the equivalent impedance using the electrochemical impedance spectroscopy technique.| File | Dimensione | Formato | |
