Li-ion batteries have become key energy storage devices in powering
various industrial processes and consumer products. Increased demand for
Li-ion batteries has raised environmental issues because most of the
batteries are landfilled upon reaching end of life. However, studies
have suggested that most of the used Li-ion batteries can be reused in
second-life applications. Battery state parameters such as the
state-of-health (SOH) and state-of-charge (SOC) are typically used for
assessing the performance. The SOH is particularly useful in predicting
the remaining life cycle of the battery and selecting suitable
second-life applications for reuse. However, measuring the SOH can be
difficult using existing technology. Recent studies have shown that a
battery's internal impedance can be used to determine the SOH of the
battery. This paper demonstrates the applicability of the internal
impedance in evaluating the SOH and suitability of used Li-ion batteries
in second-life applications. Experimental measurements from several
commercial Li-ion batteries are shown and analyzed.
