Supercapacitor | Capacitor Types | Capacitor Guide
Supercapacitors are electronic devices which are used to store extremely large amounts of electrical charge. They are also known as double-layer capacitors or ultracapacitors. Instead of using a conventional dielectric, supercapacitors use two mechanisms to store electrical energy: double-layer capacitance and pseudocapacitance.
Capacitance and Charge on a Capacitors Plates
Capacitance and Charge. Capacitors store electrical energy on their plates in the form of an electrical charge. Capacitance is the measured value of the ability of a capacitor to store an electric charge. This capacitance value also depends on the dielectric constant of the dielectric material used to separate the two parallel plates.

So not only is the total energy density of the capacitor much lower than that of the battery, we can''t even use all the energy that''s there. So we can''t effectively use capacitors in our cell phones because the phone would either last a tenth as long (probably less), or it would be ten times as large (probably more).
