Illustration of hydrated Zn ions entering and packing in pores of increasing sizes and impacts of pore size on electrochemical properties. The capacitance C is determined by C = epsilon*A/d, where A is the accessible surface area for charge carriers, d is the average distance from the ionic charge center to the electrode surface, and epsilon is the electrolyte permittivity. Pore size influences electrochemical properties by affecting A or d.
