Title: Ultracapacitor current collector

Patent ·
OSTI ID:1531457
;

An ultracapacitor comprises two solid, nonporous current collectors, two porous electrodes separating the collectors, a porous separator between the electrodes and an electrolyte occupying the pores in the electrodes and separator. At least one of the current collectors comprises a conductive metal substrate coated with a metal nitride, carbide or boride coating.
