Dielectric capacitors are vital components of electronics and power systems. The thin-film materials of which capacitors are composed are usually optimized by changing the material composition. However, Kim et al. found that postprocessing an already effective thin-film dielectric by high-energy ion bombardment further improved the material because of the introduction of specific types of defects that ultimately improved the energy storage performance. The results suggest that postprocessing may be important for developing the next generation of capacitors.

Capacitors are widely used in electronic circuits for storing and managing energy. Typical applications include filtering, decoupling, energy storage, and tuning. Some applications such as decoupling demand low impedance, high ripple current capability, and excellent surge performance. Inductance is one of the key parameters to consider when selecting a capacitor for high-speed digital circuits.

The primary effects of ESR are cell design and materials. Most of the ESR in supercapacitors is determined by how the manufacturer makes connections from the active electrode to the terminals that the customer sees. The next biggest effect is materials – electrolyte and electrode materials and how the electrode is processed.
