Abstract
An electrolyte system and an ultracapacitor are disclosed. The electrolyte system comprises a solvent, an ionic liquid comprising a cyclic compound, and a lithium metal salt. The solvent comprises a first sulfur-containing compound in an amount of from less than 85 wt. % based on the weight of the solvent and a second sulfur-containing compound in an amount of 50 wt. % or less based on the weight of the solvent. An ultracapacitor may comprise the electrolyte system.
