Capacitor with a double electric layer

摘要

This invention relates to a large capacitor for accumulating electrical energy. In particular, to a capacitor with a double electric layer comprising an electrolyte; at least one pair of electrolyte impregnated electrodes which are elastically compressible and independently, mechanically stable; and a separator also impregnated with electrolyte for being in between and in contact with both of the at least one pair of electrolytic impregnated electrodes for ionic conductance but electronically separating the electrodes; at least one pair of electrolytes impermeable and electrolyte inert current collectors in contact respectively with the at least one pair of the electrolyte impregnated electrodes; and an insulating gasket for separating the electrolyte impermeable and electrolytic inert collectors. In at least some embodiments of this capacitor, the electrolytic impregnated electrodes are composed of various forms of carbon particles in combination with porous elastic dielectrics and polymer binders.
