Essentially, a capacitor is like a small battery, producing a potential difference (i.e., a voltage) between the two plates, separated by the insulating divider called the dielectric (which can be many materials, but is often ceramic, glass, wax paper or mica), which prevents current from flowing from one plate to the other, thereby maintaining the …

Double-layer capacitance
Double-layer capacitance is the important characteristic of the electrical double layer which appears at the interface between a surface and a fluid (for example, between a conductive electrode and an adjacent liquid electrolyte). At this boundary two layers of electric charge with opposing polarity form, one at the surface of the electrode, and one in the electrolyte. These two layers, electrons on the electrode and ions in the electrolyte, are typically separated by a single layer of solvent
Voltage Doubler Design and Analysis
The voltage doubler uses a switched capacitor to double the supply voltage, shown in Figure 1. During the first half of the oscillator cycle switch S1 is closed, S2 is down and S3 is open, as shown in Figure 1a. This allows the internal capacitor to charge up to V ...
Electric Double Layer Capacitor
The EDLC is a form of energy storage device that generates electricity by creating an electrical double layer at the electrode-electrolyte interface made up of an adsorbed layer of anions and cations.

How do I increase the voltage limit by connecting same capacitors?
Most sensitive are electric double layer capacitors (supercapacitors), which are also typically rated for fairly low voltages, making the problem more relevant in moderate voltage circuit designs. Thus capacitor active balancing ICs are most often used for supercapacitor banks, such as for car audio buffer capacitors.
