The smallest cyclic ammonium salt reported to date,N,N-dimethylpyrrolidinium tetrafluoroborate(P11-BF4),was successively synthesized using a synthesis route without metal ions and halogen ions,then investigated as the electrolyte with Propylene carbonate in ED LCs.The electrochemical cha racte ristics of EDLCs assembled by 1 mol/L P11-BF4/PC paired with activated carbon electrodes were compared to traditional electrolytes.P11-BF4 has proven to have superior voltage resistance by using cyclic voltammetry and constant current charge-discharge testing.Moreover,P11-BF4 exhibits a more brilliant rate performance due to its high conductivity.These results demonstrate that P11-BF4 is an ideal electrolyte to improve the energy density and power density of supercapacitors.
