What are flexible transparent supercapacitors (ftscs)?

Flexible transparent supercapacitors (FTSCs) are the core resources due to their high optical transmittance, endurable mechanical flexibility, excellent electrochemical performance, and facilely accessible device configuration. This review organizes the rational design of nanostructured electrode materials toward FTSCs.

Which supercapacitor has the highest volumetric capacitance?

In comparison to the state-of-the-art all-solid-state ultrafast flexible supercapacitors, the as-fabricated flexible PEDOT:PSS-based supercapacitor provides the highest volumetric capacitance of 38 F cm −3 in the high-frequency regime (e.g., 120 Hz) while maintaining a sufficient ultrafast response speed for 60-Hz AC line filtering applications.

Why are flexible supercapacitors important?

Flexible supercapacitors are among the most important power supply devices for fulfilling the energy/power demands of future flexible and wearable electronics. While significant achievements have been made in improving the energy density of the flexible supercapacitors, ultrafast flexible supercapacitors remain in their infancy.

Are supercapacitors a good energy storage device?

Among various energy storage devices, the supercapacitors (SCs) have received great attention due to their high power densities, excellent cycle stability, superior safety, and cost effectiveness , , , , . However, the practical and wide-range applications of the SCs are severely restricted by their low energy densities , .

How is a supercapacitor cell assembled?

A supercapacitor cell was assembled using two EP-PEDOT:PSS electrodes coated on each Au/Ti/Ti foil current collector, a poly (tetrafluoroethylene) (PTFE) separator (thickness = 30 µm, pore size = 0.1 µm, Millipore), and an H 2 SO 4 -PVA gel electrolyte.

What is a high-performance intrinsically-flexible transistor?

More specifically, for high-performance intrinsically-flexible transistors, realizing high-performance intrinsically-flexible dielectrics is more critical and challenging, which requires high dielectric constant, low dielectric loss, excellent mechanical properties, patterning capability, and process compatibility.
