The purpose of this research is to demonstrate the difference in the battery capacity in terms of Remaining Useful Life (RUL), focusing on how these conditions influence battery performance. To assess the electrochemical performance of both fresh and aged batteries, repeated charge-discharge cycles will be conducted. Moreover, electrochemical impedance spectroscopy will be utilized to investigate the thermal performance degradation, with a special emphasis on alterations at the electrode/electrolyte interface. This investigation aims to identify the storage conditions that significantly affect battery lifespan. Additionally, it seeks to explore the differential impacts of these conditions on batteries with varying levels of remaining capacities.
