It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively. A circuit containing both an inductor (L) and a capacitor (C) can oscillate without a source of emf by shifting the energy stored in the circuit between the electric and magnetic fields.
The State of stored Energy describes the ratio of the stored energy E stored, which can ideally be discharged starting at time t, to the maximum stored energy E max,stored. Since the charge amount that can be stored in the battery decreases, and the OCV curve shifts with progressive aging, the maximum stored energy decreases

Mechanical Engineering questions and answers. 4.15. In electronic camera flash units a capacitor is charged from an electronic power supply, and its stored energy is discharged through the flash tube to create the flash. The electronic power supply is not an ideal source, that is, it cannot be modeled as a voltage source or a current source.
In particular, in all nanocomposites, the nanocomposite filled with 3 vol% dopa@STnws exhibits highest discharged energy density of 8.8 J/cm 3 and highest discharge efficiency of 45% simultaneously. In fact, the improvement of energy storage performance is attributed to the enhanced difference between D max and P r in the D-E
