ELECTROCHEMICAL SUPERCAPACITOR Russian patent published in 2013 - IPC H01G9/00 H01G11/00 

FIELD: electrical engineering.

SUBSTANCE: electrochemical supercapacitor contains a self-supported housing with power clamps, at least one compacted package of elements including two separators, heteropolar electric electrodes of carbon material particles, positioned on one surface of the separators, impregnated with an electrolyte, two electrically conductive collectors, positioned between the electrodes and projecting outside the electrodes and separators edge, and current terminals. The electrically conductive collectors envelope the electrodes and are insulated along the perimeter with a sealing coating consisting of two layers. The first layer is made of a non-hardenable polymer composition while the second layer is made of a mixture of individual polytetrafluorethylene particles including open-porous coarse particles, with a size equal to 0.5-1.0 of the distance between the collectors, and fine polymer particles sized 20-400 mcm, the contents of coarse particles being within the range of 50-80% of the mixture quantity.

EFFECT: enhanced tightness of the supercapacitor and exclusion of the probability of electrolyte straps formation between storage cell elements and cells of elements.
