Are electrochemical supercapacitors effective in Microsystems?
Electrochemical supercapacitors stand out with their superior capacitance density, surpassing traditional electrolytic capacitors by at least two orders of magnitude. However, the intrinsic slow ion dynamics of electrical double layer effects greatly limit supercapacitors characteristic frequency, constraining their applicability in microsystems.
What are electrochemical supercapacitors?
Electrochemical supercapacitors (SCs), which are based on the electric double layer (EDL) effect, have emerged as a promising alternative, offering significantly higher capacitance densities and the capability for on-chip fabrication 7, 8, 9.
Why do microelectronics need supercapacitors?
The prosperity of microelectronics has intensified the requirement for miniaturized power systems using capacitors with high capacity and broad frequency ranges. Electrochemical supercapacitors stand out with their superior capacitance density, surpassing traditional electrolytic capacitors by at least two orders of magnitude.
