Capacitive and non-capacitive faradaic charge storage
2. Non-faradaic capacitive storage. The capacitance of a conventional capacitor typically ranges between 10 −6 –10 −2 F, therefore the energy stored in the capacitor is too small for meaningful practical uses. For example, for a 50 mF capacitor with an applied voltage of 100 V, the energy stored is only 250 J.
