Supercapacitor Consisting of a Form Core Sandwich with Woven Carbon Fiber Skin ()
ABSTRACT
Structural capacitors are composite structures that function as energy storage capacitors. Parallel
plate-type capacitors have the advantage of high voltage resistance, but are limited by low capacitance.
An electric double-layer capacitor with a composite structure using a solid polymer electrolyte
matrix with a glass fiber fabric separator has recently been developed. However, the solid
polymer electrolyte caused the capacitor to possess high internal resistance. In the present study,
a new design of supercapacitor using a form core sandwich with high water retention is proposed
and experimentally investigated. Activated carbon sheets are used as electrodes on the form core
sandwich to make a supercapacitor. Woven carbon fabric is used as lead wires of the supercapacitor.
The resulting supercapacitor displays a low surface resistance of 810 Ωcm2 and high areal
capacitance of 520 mF/cm2.
