In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals.
Supercapacitor is supposed to be in between a Capacitor and battery. These types of capacitors charge much faster than a battery and charge more than an electrolytic capacitor per volume unit. That is why a supercapacitor is considered between a battery and an electrolytic capacitor.
When a capacitor is connected to a battery, the charge is developed on each side of the capacitor. Also, there will be a flow of current in the circuit for some time, and then it decreases to zero. Where is energy stored in the capacitor? The energy is stored in the space that is available in the capacitor plates.
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed. Take, for example, the flashbulb in a camera.
A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly. How much can we charge? When connected to a cell or other power supply, electrons will flow from the negative end of the terminal and build up on one plate of the capacitor.
This happens because the capacitor is first charged by the battery. When you disconnect the battery, the stored charge in the capacitor flows through the resistor and LED and thereby keeping the LED on for a few more seconds, until the capacitor is discharged. So the capacitor works similarly to a battery – it can be charged and discharged.

A battery is an electronic device that converts chemical energy into electrical energy to provide a static electrical charge for power, whereas a capacitor is an electronic component that stores electrostatic energy in an electric field.
Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. …
A capacitor is a little bit like a battery in that both store electrical energy. But how they work is completely different. A capacitor is also much simpler than a battery, as it can only store …

A camera flash might get its power from a capacitor (which, in turn, was probably charged by a battery). Battery or Capacitor? ... A very simple example of an audio crossover circuit. The …
The capacitor is a component which has the ability or "capacity" to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable battery.
At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage …
