Abstract
Lithium-ion capacitors (LICs) have attracted more and more attention as energy storage device candidates because of their high energy density, high power density and high security. It is important to predict lifetime for various applications in advance. Further research is needed for searching suitable application scenarios of LICs. In the paper, a simulation platform for predicting the lifetime of LICs is established, combining fractional-order electrical model, lumped parameter thermal model and aging model. The results show that the coupling between the models can effectively reduce the prediction relative error by 4 %. The platform can be used to predict cycling and calendar lifetime of LICs under actual operating conditions, reducing the investment of trial and error in scenario selection.
