6 FAQs about [Solid-state wound capacitors]

Do bulk-type all-solid-state capacitors have superior electrochemical performance?

Are solid-state supercapacitors the future of energy storage?

What is a thermally stable all-solid-state capacitor with oxide electrolyte?

Thermally stable all-solid-state capacitor with oxide electrolyte is developed. Highly-deformable electrolyte and carbon nanotube are mixed to obtain electrode. The fabricated capacitor is operable at 100–300 °C with high capacity.

Are solid-state electrolytes a supercapacitor?

Solid-state electrolytes possess excellent physical flexibility, desirable electrochemical properties, and high mechanical integrity [ 29, 30, 31, 32 ]. They can not only serve as the electrolyte, but also function as the separators. If the thickness of the solid-state electrolytes can be reduced, ultrathin supercapacitors would be achieved.

What happens if a capacitor is exposed to high temperatures?

When exposing the capacitors to high temperatures, there appears the shrinking and expansion of the dielectric films, which eventually leads to disconnection due to the different thermal mismatch with the end sprayed metal. This delamination or defects will cause higher impedance and dissipation factors, as described in the next section.

What is the operating voltage of nanostructured all-solid-state supercapacitors with a sulfide se?

The operating voltage of nanostructured all-solid-state supercapacitors with a sulfide SE was 0.5 V , lower than those of capacitors with aqueous solutions and organic liquid electrolytes.
