Capacitors
A capacitor can discharge all its stored energy in a tiny fraction of a second, where a battery would take minutes to completely drain itself. That''s why the electronic flash on a camera uses a capacitor -- the battery charges up the flash''s capacitor over several seconds, and then the capacitor dumps the full charge into the flash unit.
