Explainer: How batteries and capacitors differ
When it comes to circuits and electronic devices, energy is typically stored in one of two places. The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential.

Understanding Supercapacitors and Batteries | DigiKey
Batteries provide high energy density. Supercapacitors have lower energy density than batteries, but high power density because they can be discharged almost instantaneously. The electrochemical processes in a battery take more time to deliver energy to a load. Both devices have features that fit specific energy storage needs (Figure 1).

What is the difference between a capacitor and a battery?
While capacitors and batteries differ in several aspects, they also share some similarities: Energy Storage: Both capacitors and batteries store electrical energy using different mechanisms. Application Variety: Capacitors and batteries find applications in various industries, including electronics, automotive, and renewable energy sectors.
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.
How does a capacitor store energy?
Capacitor: A capacitor stores energy in an electric field. It consists of two conductive plates separated by a dielectric material. Capacitors can rapidly charge and discharge energy. They have a lower energy density compared to batteries, but they can deliver high power bursts.
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.
Why do batteries waste more energy than capacitors?
This is because the production and disposal of batteries require more energy and create more waste than capacitors. Furthermore, the lifespan of batteries is limited, and they need to be replaced more frequently, resulting in more waste.
What happens when a capacitor is connected to a battery?
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.
