Title: Electrolytes for supercapacitors

Abstract

A supercapacitor and a related electrolyte composition suitable for use in a supercapacitor are provided. An electrolyte composition can include a conductive sodium salt component comprising NaTFSI and a non-aqueous solvent component comprising dimethoxy ethane (DME). The conductive sodium salt component and the non-aqueous solvent component can be present at a molar ratio of NaTFSI:DME of 1:1 to 1:3, inclusive.
