The problem is capacitors have a much lower energy density than batteries; they just can''t pack as much energy as an equally sized chemical battery (but that gap is narrowing!). The upside of capacitors is they usually lead longer lives than batteries, which makes them a better choice environmentally.

capacitor

That fact that the battery may also store that much energy does not mean that there is a capacitor equivalent to a battery. While an ideal battery maintains the voltage across its terminals until the stored energy is exhausted, the voltage across an ideal capacitor will gradually approach zero as the stored energy is depleted.

6 Frequently Asked Questions about “How capacitors act as batteries”

Is a capacitor a battery?

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.

How does a battery capacitor work?

The plate on the capacitor that attaches to the positive terminal of the battery loses electrons to the battery. Once it's charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor). For a small capacitor, the capacity is small. But large capacitors can hold quite a charge.

Can a capacitor replace a battery?

Not exactly. While you can use a capacitor to store some energy, its ability to replace a battery is limited due to its low energy storage capacity. Capacitors vs batteries aren't interchangeable, but in specific use cases, capacitors can complement or assist batteries.

Are capacitors good for a battery?

Capacitors are good for applications that need a lot of energy in short bursts. The energy storage capacity of a battery or capacitor is measured in watt-hours. This is the number of watt hours a battery or capacitor can store. Usually, batteries have a higher watt-hour rating than capacitors.

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 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?
