A novel electrolytes applied in electrochemical double-layer capacitors(EDLCs) were prepared based on TEA-BF4 and EMIM-BF4. The electrolyte was prepared by adding Χ wt.% EMImBF4 into standard electrolyte solution, TEABF4/PC/ACN. For comparison, pure EMImBF4 without TEABF4 and TEABF4 dissolved in PC/ACN(TEABF4/PC/ACN) were used as electrolyte. The ionic conductivity, viscosity, and electrochemical performances of PC/TEABF4/EMImBF4/ACN mixtures were determined. The ionic conductivity of the electrolytes was measured by AC impedance, and the electrochemical performances of the electrolytes were elvaluated by using cyclic voltammetry. Cyclic voltammetry (CV) was performed within 0–2.5 V with scan rates of 10 mV s−1, 30 mV s−1 and 50 mV s−1, respectively. |
