1. Technology Overview

The present invention relates to, according to one aspect, a method for preparing a polymer electrolyte using ionic liquid, and according to another aspect, a polymer electrolyte made therefrom for electric double layer capacitor (EDLC) application. The ionic conductivity of the polymer electrolyte ranges from 8 to 11 mS cm-1 at a temperature ranging from 22ºC to 26ºC; the glass transition temperature (Tg) of the polymer electrolyte is in the range from 22ºC to 47ºC; the percentage of crystallinity is substantially in the range from 1% to 3%; and the electrochemical potential of the polymer electrolyte ranges from 3.3 V to 3.8 V.  The polymer electrolyte is for forming an electric double layer capacitor (EDLC). The EDLC is formed in a configuration of electrode-polymer electrolyte-electrode and the electrodes are activated carbon-based electrodes. The capacitance of the EDLC ranges from 0.1 F g-1 to 55 F g-1, the energy density of the EDLC ranges from 5 W h kg-1 to 9 W h kg-1, the power density of the EDLC ranges from 40 kW kg-1 to 60 kW kg-1, and the Coulombic efficiency of the EDLC is the range from 70% to 85%.
