Capacitors function a lot like rechargeable batteries. The main difference is a capacitor''s ability to store energy doesn''t come from chemical reactions, but rather from the way that its physical design allows it to hold negative and positive charges apart. This makes capacitors very fast at charging and discharging, much faster than batteries.
