Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance.
The capacitance of any capacitor is proportional to the permittivity of the dielectric i.e., the higher the permittivity of the dielectric higher the capacitance of that capacitor. The dielectric constant and permittivity of various dielectrics materials are given as follows:

Double-layer capacitance is arising from potential-dependence of the surface energy stored electrostatically at the interface of capacitor electrodes. In this type of supercapacitors, there is no electron exchange and no redox reaction and the energy is stored non-faradaically. The key point to obtain an extremely high capacity is the large surface of the
Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However
