An electrolyte for an electrochemical double layer capacitor and an EDLC utilizing such an electrolyte are disclosed. The electrolyte can include a solution of an organic salt or a combination of organic salts, the salts including cations and anions, and a single organic solvent or a mixture of organic solvents, wherein the electrolyte has a boiling point above 100&#xb0; C., electrochemical stability at voltages between 2.7 V, and a viscosity below 2 mPa&#xb7;s at a temperature of 100&#xb0; C. The electrolyte may contain an organic solvent or a mixture of organic solvents having boiling points above 100&#xb0; C. and melting points below 0&#xb0; C.

A method of selecting the nanoporous carbon material for at least one of the polarizable electrodes (positive and/or negative) of EDLC with given organic electrolyte is suggested. The method includes providing of a number of nanoporous carbon materials, which can potentially be used for manufacturing the EDLC electrodes, impregnating the materials with the selected electrolyte followed by measuring the diffusion coefficients of anions and cations of the electrolyte inside the pores of the carbon materials and selecting for positive and negative electrodes the carbon materials, which provide the maximum diffusion coefficients of anions and cations, respectively. A method of manufacturing polarizable electrodes (positive and/or negative) and a method of manufacturing electrochemical double-layer capacitor based on the said method of selecting the nanoporous carbon material are also suggested.
