Can a capacitor act as a battery?

Capacitors discharge rapidly while batteries discharge slowly as required by most electrical applications. However, a new type of capacitor known as supercapacitor is capable of storing electric energy much like batteries. The following are some of the features that allow it to function as a battery:

  • They discharge slowly like batteries
  • They can be recharged rapidly
  • They can be recharged again and again without degradation

However, more research needs to be done on this technology which would be time and cost-intensive. Supercapacitors need to evolve a lot before they actually replace batteries.
