How to Make a Capacitor
A capacitor is a device for storing a small electric charge. When two conductive plates are separated by a small insulator called a dielectric, they produce an electric field. The strength of this field is called the capacitance of the capacitor.
batteries
The capacitor charging circuit is simple: a series resistor R1 to limit charge current through D1 into the capacitor bank C2. If the power-up events are rare, the energy loss on R1 is not substantial and doesn''t have undue impact on the energy efficiency of the device.
Paper Capacitor : 11 Steps
Basically capacitor is a passive component which store charges in it. The stored energy is in the form of electric energy in the electric field between the plates.

How to make a super capacitor jump starter that doesn''t empty into battery?
$begingroup$ @ManRow: - no - the battery is required to hold the alternator output voltage down to the 13.6 - 14.4 volt range. I, and many others, have determined this experimentally (accidently) by disconnecting the battery and destroying electronics. This is probably more common with boats, where we have a battery disconnect switch, than with cars.
How to Discharge a Capacitor (with Pictures)
If the capacitor reads as having fewer than 10 volts, you don''t need to discharge it. If the capacitor reads anywhere between 10 and 99 volts, discharge it with a screwdriver. If the capacitor reads in the hundreds of volts, the safest way to discharge it is with a discharge tool, rather than a screwdriver.
