| Popis: | This work depicts the calendar aging results of four Li-ion battery technologies. The differences in the chemistry of Li-ion batteries was studied and revealed that cathodes containing manganese are more sensitive to state-of-charge and temperature increase than lithium–iron-phosphate or lithium–nickel–cobalt–aluminum batteries. The first step in presenting the differences in technology of the Li-ion battery is through the study of the battery voltage evolution versus the amount of charge at various states of health. This study revealed a significant increase in resistance on lithium–nickel–manganese–cobalt and lithium–manganese-oxide cells; a result which was confirmed through impedance spectroscopy measurements. Finally, a study of the comparison of the different types of Li-ion batteries was undertaken, based on the analysis of the evolution of energy efficiency with respect to aging. |
