Modeling of Capacitance in A Supercapacitor

open access: yesJournal of Engineering Technology and Applied Physics, 2019
A general supercapacitor model is developed by incorporating the effective surface area in the presence of pores. An analytical solution has been derived from the generic equation in Laplace domain based on the porous-electrode theory.
