Microstructural Analysis and Mathematical Modeling of Electric Double-Layer Supercapacitors

摘要: For hybrid-electric vehicle applications, supercapacitors show promise for providing low cost per unit power, high-efficiency energy storage, substantially temperature-invariant operation, and high cycle life (potentiallyequating to one supercapacitor pack lifetime). Here we provide a microstructural mathematical analysis the characterization of relatively specific supercapacitor. The governing equations boundary conditions are generalized so that cell can be modeled using current, potential, or power excitation source. An Appendix clarifies role binary-electrolyte diffusion. overall allows determine optimal target operating voltage hybrid calculate available vs. system, clarify electrode utilization through examination stored charge as function position.
