Abstract
Embodiments described herein relate generally to electric double layer capacitors having an electrolyte formulation that includes a quantity of a stabilizing additive such that the electrochemical double layer capacitors retain cell capacitance for longer periods of time, generate less gas during operation, and experience less long term ESR. In some embodiments, an electrolyte formulation includes an ionic species, a solvent, and a stabilizer. In some embodiments the stabilizer contains a moiety that promotes adsorption to a surface, such as a carbon surface, and a moiety that promotes polarity of the stabilizer. In some embodiments, the solvent can be a nitrile compound and the stabilizer can be a compound of the formula I:
