FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, namely to a supercapacitor for systems of autonomous power supply and portable start of motor vehicles. Current-conducting collectors and separators of the assembly have surfaces repeating relief of electrodes and a porous structure obtained by molding collectors with application to electrode material of a nickel layer with a thickness of 50-70 mcm by a galvanic method and separators by spraying an aqueous cellulose solution on electrodes with subsequent vacuum impregnation of the supercapacitor assembly with an electrolyte, which allows for optimal filling of porous structures with the electrolyte.
EFFECT: increase in stability of operation of a supercapacitor due to reduction in electrical resistance.
