As a new energy storage element

supercapacitors have characteristics such as high power density

fast charge and discharge rates

green environmental protection

and long cycle life. Temperature is an important parameter of supercapacitors which significantly influences the stability of the supercapacitors. In this study

the finite element method is used to realize a coupling between a one-dimensional electrochemical model and a three-dimensional thermal model. Then

based on this model

the concept of limited cycle numbers is defined

and different unit quantities

unit size

and the effect of temperature under different temperature environments such as low temperature

room temperature

and high temperature on stacked-type supercapacitors is studied. Finally

stacked-type supercapacitors are compared with rolled-type supercapacitors considering the same cell size

density

and volume approximations. The simulation results show that the higher the number of packaging units

the lower is the limit cycle number. This phenomenon is more pronounced under high current than under low current conditions. Increasing the package size of the porous electrode or separator decreases the limiting cycles. Under the same unit volume scenario

improving the separator size proportion can accurately control the temperature rise at small current values. Under the same material

volume

and density approximations

the temperature rises slowly for stacked-type supercapacitors as compared to rolled-type supercapacitors. This phenomenon is more pronounced with an increase in current.
