The Effect of Storage Temperature in Remaining Useful Life of Lithium Ion Battery

Energy icon, disabled. An orange lightning bolt.

Remaining useful life (RUL) of rechargeable batteries can decay permanently when they are exposed to high temperature due to undesired material degradation. In this project, the research team investigates the effects of storage temperature in RUI by exposing one group of 40 mAh capacity rechargeable lithium-ion button-type batteries to room temperature (25℃), and one to 65℃. We conduct galvanostatic charge-discharge cycling test and internal resistance measurement test and the obtained data is analyzed to demonstrate unusual battery behavior that represents failure of the aged batteries stored at high temperature.
