Can a capacitor act as a battery
A new type of capacitor known as a supercapacitor is capable of storing electric energy much like batteries.

To deal with the slowness of the battery, capacitors are charged from the battery and can be discharged when fast power is needed.

It turns out that

6 Frequently Asked Questions about “Capacitors act like batteries”
Is a battery a capacitor?
Since the energy stored in the capacitor is proportional to the square of the voltage, once the voltage drops off significantly, the current will increase in inverse proportion and so the remaining energy will be extracted quite quickly. Bear in mind that batteries typically have much higher capacity than capacitors. The simple answer is no.
Can a capacitor replace a battery?
It is common knowledge that capacitors store electrical energy. One could infer that this energy could be extracted and used in much the same way as a battery. Why can capacitors then not replace batteries? Conventional capacitors discharge rapidly, whereas batteries discharge slowly as required for most electrical loads.
Can a battery and a capacitor work together?
Yes, capacitors and batteries can complement each other in certain applications. Capacitors can be used to provide quick bursts of energy, while batteries handle sustained power supply. How do solar cells work to generate electricity explained simply?
Can a battery store more energy than a capacitor?
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.
Can You charge a capacitor with a battery?
However, for devices that need consistent, long-term energy supply, a battery is still the best option. You can easily charge a capacitor using a battery. The charging process is quick, and this is commonly done in circuits where capacitors are used to smooth out power supplies or manage energy flow.
Can a capacitor store electrical energy?
Although capacitors can store electrical energy, much like batteries do, they are used in very different applications. The characteristic property of capacitors is their ability to discharge their energy stores very quickly. A very common application of this “burst” capacity is in the electronic flash of cameras.
