Abstract
A comprehensive study of the factors influencing the cycle life of Li-ion capacitors (LiCs) at different stages of aging is essential for a promising LiC energy management system. This digest explicitly studies the factors influencing the initial stage of aging of LiCs. The commercially available Musashi LiC cells are chosen to perform cyclic aging experiments under different test conditions, including temperature, C-rate, and cycle depth. The results demonstrate the impact of the test conditions on LiC aging. A notable observation is that depth-of-discharge also significantly affects the initial aging stage. Finally, the Arrhenius equation has been applied to the test results and qualitatively analyzed the cell degradation mechanism.
