Title: Ultracapacitor electroyte

Abstract

The invention relates to an ultracapacitor and to a method of making an ultracapacitor. The ultracapacitor of the invention includes 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. The electrolyte includes a cyclic carbonate solvent, a cyclic ester solvent and an electrolyte salt. The invention also relates to a stack of ultracapacitor cells.
