Abstract: This paper presents a simulation of electric potential distribution, electric field intensity and temperature in the spiral wound supercapacitor. The paper simulation using the 3-D finite element method that all coded by MATLAB program and show the graphical representation for electric potential, the electric field intensity and temperature of inner part for a supercapacitor and studies the permittivity of the electrolyte that affect the electric field intensity and temperature of supercapacitor. The simulation results show an electric field intensity and temperature of the inner part with various electrolytes including KOH and sodium iodide in various solvents electrolyte. Solvents of sodium iodide consist of CH3OH, (CH3)2SO, HCONH3 and HCONHCH3 that have different relative permittivity. It can indicate to the working process of supercapacitor.

Keywords: Voltage regulation, voltage control, energy storage, distribution networks, power factor
